It has a yellow bill with a red subterminal spot (this is the small spot near the end of the bill that chicks peck in order to stimulate feeding).

The House Sparrow (Passer domesticus, female shown here) is a member of the Old World sparrow family Passeridae. It occurs naturally in most of Europe and much of Asia, but has been introduced to most other parts of the world. Despite being so common, it is often confused with the smaller and slimmer Tree Sparrow.

The Blue Jay (Cyanocitta cristata) is a North American jay which can be found over a very large area of the eastern side of the continent. It is mainly a bird of mixed woodland, but also of parks and gardens in some towns and cities. Its food is sought both on the ground and in trees and includes virtually all known types of plant and animal sources.

The Barred Owl (Strix varia), commonly known as the hoot owl, is a large typical owl. Its breeding habitat is dense woods across Canada, the eastern United States and south to Central America. They hunt at dawn, dusk, or night, by waiting on a high perch or flying through the woods and swooping down on prey. They mainly eat small mammals, such as mice and rabbits, and also small birds.

The Black-chinned Hummingbird (Archilochus alexandri, female shown here) is a small hummingbird found in open semi-arid areas near water in the western United States, northern Mexico and southern British Columbia. They are migratory and most winter in Mexico.

A female American Wigeon (Anas americana), a common and widespread duck which breeds in northern North America. It is the New World counterpart of the Eurasian Wigeon. This dabbling duck is strongly migratory and winters further south than its breeding range.

A House Sparrow, a "true sparrow" of the family Passeridae, as opposed to American sparrows. There are other birds, such as the Dunnock, also known as a Hedge Sparrow — a relic of the old practice of calling any small bird a "sparrow". There are 35 species of Old World sparrows, in four genera.

A female Spruce Grouse (Falcipennis canadensis), a medium-sized grouse native to the boreal forests or taiga across Alaska, Canada and the northern United States. Grouses nest on the ground in dense growth. They are not migratory, but some move short distances by foot to a different location for winter.

The Black-headed Gull (Larus ridibundus) is a small gull which breeds in much of Europe and Asia, and also in coastal eastern Canada. Despite the name, the gull's head is only black during the summer. In winter the head becomes white as seen here, leaving just dark vertical streaks.

The Australian Pelican (Pelecanus conspicillatus), also known as the Goolayyalibee, is a species of pelican widespread on the inland and coastal waters of Australia and New Guinea. Compared to other pelican species, they are medium-sized: 1.6 to 1.8 m (5.25 to 6 ft) long with a wingspan of 2.3 to 2.5 m (7.6 to 8.25 ft) and weighing between 4 and almost 7 kg (9 to 15 lbs). They are predominantly white, with black and white wings and a pale, pinkish bill which, like that of all pelicans, is enormous—particularly in the male.

A juvenile Red-tailed Hawk eating a California Vole. This act, called predation, is a biological interaction where a predator species kills and eats others, known as prey. Predators are either carnivores or omnivores. Herbivores are usually treated separately, but from an ecological perspective, the activities of the herbivorous species that kill the organism they feed on is functionally the same as predation.

A male Rock Pigeon (Columba livia) in flight. This species of pigeon, native to western and southern Europe and North Africa, is known throughout the world, although pure Rock Pigeons are increasingly rare, having been displaced by the domesticated version. Some pigeon breeds such as homing pigeons have been extremely useful to humans.

A Black-bellied Whistling Duck (Dendrocygna autumnalis) in mid-flight. This species of whistling duck breeds in the southernmost United States and tropical Central and South America. As the name implies, these are noisy birds with a clear whistling waa-chooo call.

The tail is white with a dark band at the end. The distinctive black and white pattern of the wings is a common sight along many North American coastal beaches.

An Eastern Striated Pardalote (Pardalotus striatus ornatus) with nesting material in its mouth. This subspecies of the Striated Pardalote, the least colourful and most common of the four pardalote species, is found in subtropical areas of Eastern Australia. They are more often heard than seen, foraging noisily for lerps and other small creatures in the treetops.

The Red-necked Grebe (Podiceps grisegena) is a member of the grebe family of water birds. In summertime, adults are unmistakable, due to their red neck and white throat. In winter, the Red-necked Grebe is duskier than most grebes, with no white above the eye, and a thick, yellowish bill. It is a somewhat large grebe, about the same size as an average duck.

The Magnificent Hummingbird (Eugenes fulgens, female shown here) is a large hummingbird that breeds in mountains from the southwestern United States to western Panama. The bird appears very dark unless the sun catches the iridescence of the plumage and the brilliant colours flash in the sunlight. It is generally about 13 cm long, with males weighing 10 g and females 8.5 g. The black bill is long and slightly curved.

The Tawny Owl (Strix aluco) is a species of owl resident in much of Europe and southern Russia. It is a medium-sized earless owl, 37-43 cm in length with an 81-96 cm wingspan. The Tawny Owl is stocky with a large rounded head and rounded wings. This species probably injures more people than any other European bird. It is fearless in defence of its nest and young, and strikes for the intruder's face with its sharp talons. Since its flight is silent, at night in particular it may not be detected until too late.

The Glossy Ibis (Plegadis falcinellus) is a migratory wading bird in the ibis family Threskiornithidae. It is the most widespread ibis species and can be found in warm regions of Europe, Asia, Africa, Australia, and the Atlantic and Caribbean region of the Americas. The Glossy Ibis falls under the conservation protection of the Agreement on the Conservation of African-Eurasian Migratory Waterbirds.

Wilson's Snipe (Gallinago delicata) is a small, stocky shorebird common to Canada and the northern United States. In appearance the bird is similar to the Common Snipe, which can be found in northern Europe and Russia. Normally shy, the bird prefers to remain hidden in marshy grasses and watered fields, probing for worms and other invertebrates with its sensitive beak. In spring and early summer the Snipe is heard and seen more frequently as male birds search for mates and pairs establish nesting locations.

A young fluffed up female Blackbird (Turdus merula). Unlike males, who are all black except for a yellow eye-ring and bill, females have brown plumage and a brown beak. Blackbirds are common in woods and gardens over all of Europe and much of Asia south of the Arctic Circle. Females are aggressive in the spring when competing with others for good nesting territory.

The Yellow Warbler (Dendroica petechia) is a New World warbler. It is the most widespread Dendroica warbler, breeding in almost the whole of North America and down to northern South America.

It is a unique member of the order Anseriformes, and arranged in a separate family and genus.

The California Condor (Gymnogyps californianus) is a critically endangered species of North American bird in the New World vulture family Cathartidae. It has the largest wingspan of any bird found in North America and is one of the heaviest. The condor is a scavenger and eats large amounts of carrion. The California Condor is one of the world's rarest bird species. In 1987, all 22 remaining wild individuals were captured. Thanks to captive breeding, numbers rose, and beginning in 1991, they were reintroduced to the wild. As of March 2008, there are 297 condors known to be living including 146 in the wild.

The Great Blue Heron is a wading bird in the heron family, common over most of North and Central America as well as the West Indies and the Galápagos Islands. Great blue herons can be found in a range of habitats, in fresh and saltwater, but always near bodies of water. They feed by using their long legs to wade into the water and then catch fish or frogs with their long bill.

A Red-headed Woodpecker (Melanerpes erythrocephalus) hanging on a bird feeder. This woodpecker species' breeding habitat is open country across southern Canada and the eastern-central United States.

It is about 20 cm (8 in) long, with a glossy dark blue crown, a grey back and white underparts. It is similar to the Willie Wagtail, though the lack of a black throat & white eyebrow are distinguishing features. Its main food is insects.

The American Robin (Turdus migratorius) is a migratory songbird of the thrush family. The similarity between the orange-red coloring of its breast to that of the smaller and unrelated European Robin (Erithacus rubecula) led to its common name. It is widely distributed throughout North America, wintering south of Canada from Florida to central Mexico and along the Pacific Coast.

Two Welcome Swallow (Hirundo neoxena) chicks, one day after fledging. The Welcome Swallow is a small passerine bird in the swallow family native to Australia and nearby islands, but not until recently to New Zealand. It is very similar to the Pacific Swallow.

The Bufflehead (Bucephala albeola) is a small American sea duck of the genus Bucephala. The name Bufflehead is a combination of buffalo and head, referring to the oddly bulbous head shape of the species. This is most noticeable when the male puffs out the feathers on the head, thus greatly increasing its apparent size.

A Brolga (Grus rubicunda), sometimes known as the 'Native Companion' or 'Australian Crane', in Victoria, Australia. This individual is approximately 1 metre (3.3 ft) in height. A common gregarious wetland bird species in tropical and eastern Australia, the Brolga is well known for its intricate mating dance.

The Eastern Imperial Eagle (Aquila heliaca) is a bird of prey from the Accipitridae family. It is a close relative to the Spanish Imperial Eagle and very similar to the Golden Eagle, but a little smaller and less powerful. The species can be found in Southeast Europe, West and Central Asia, but has nearly vanished from much of its former distribution area of Hungary and Austria.

The Greater Yellowlegs (Tringa melanoleuca, juvenile shown here) is a mid-sized shorebird similar in appearance to the smaller Lesser Yellowlegs. The Greater Yellowlegs can be distinguished from the Lesser Yellowlegs by its larger size and relatively longer bill. The bill of the Greater Yellowlegs is longer than the head, while the bill of the Lesser is about the same length.

A hand-colored engraving of the Ivory-billed Woodpecker (Campephilus principalis), a very large member of the woodpecker family Picidae native to the Southern United States. This species is officially listed as an endangered species, but by the end of the 20th century had widely been considered extinct. Sightings in Arkansas in 2004 and 2005 were followed by evidence for existence in Florida in 2006, but conclusive evidence of a population of Ivory-billed Woodpeckers, in the form of unambiguous photographs/videos, specimens, or DNA from feathers, has not been forthcoming.

The Willie Wagtail (Rhipidura leucophrys) is a passerine bird native to Australia, New Guinea, the Solomon Islands, the Bismarck Archipelago, and eastern Indonesia. It is a common and familiar bird throughout much of its range, living in most habitats apart from thick forest.

The Long-billed Corella (Cacatua tenuirostris) is a cockatoo native to Australia. The species can be found in the wild around western Victoria and southern New South Wales. Feral populations have sprung up in Sydney, Perth and Hobart from the release of unwanted birds.

A Silvereye (Zosterops lateralis) perched on a blooming Cestrum species. The Silvereye is a very small passerine bird (~12 cm (4.7 in) in length) native to the Australasia region. Silvereyes are omnivorous but have a particular fondness for fruit. Some orchardists, grape growers, and home gardeners regard them as a pest particularly as, being so small, Silvereyes simply ignore bird nets, popping in and out through the netting at will.

A Greater Crested Tern (Thalasseus bergii) displaying in breeding plumage. This member of the tern family nests in dense colonies on coastlines and islands in the area from South Africa around the Indian Ocean to the central Pacific and Australia. It is closely related to the Royal and Lesser Crested Terns, but can be distinguished by its size and bill colour.

The crown pattern is variable, with the white occasionally spreading down the neck; the variability makes identification of individuals possible. The beak is black and often pale grey at the base.

The Laughing Kookaburra (Dacelo novaeguineae) is a carnivorous kookaburra in the Kingfisher family well known for its laughing call. It is about 45 cm (18 in) in length and is found throughout eastern Australia and neighboring islands, and has been introduced to southwestern Australia as well as Kawau Island near New Zealand. Its trademark "laugh" is to establish territory amongst family groups. When one bird starts, often others will join in, including nearby birds from rival tribes, which can fill the bush with their calls.

The Red Wattlebird (Anthochaera carunculata) is a large species of honeyeater found across southern Australia. Growing up to 35 cm (14 in) in length, it has distinctive red wattles, white streaks on the chest and belly, and a bright yellow patch towards the tail.

Its habitat is still freshwater lakes, paddy fields or reservoirs with plentiful vegetation, where it feeds mainly at night on seeds and other parts of plants.

The Pied Oystercatcher (Haematopus longirostris) is a wader native to Australia, where they can be found on sandy coastlines feeding on various bivalve molluscs, but not actually oysters, which are found mostly on rocky shorelines. This oystercatcher species is easily recognized by the characteristic 5–8 cm (2–3 in) long orange-red beak, slender pink legs and black and white plumage.

The Nankeen Kestrel (Falco cenchroides), native to Australia, New Guinea, and nearby islands, is one of the smallest species of falcon (about 31 to 35 cm (12 to 14 in) in length). Unlike other raptors, it does not rely on speed to catch its prey. Instead, it simply perches in an exposed position, but it also has a distinctive technique of hovering over crop and grasslands.

The House Sparrow (Passer domesticus, male shown here) is the most widely distributed wild bird. It originated in the Middle East and has spread throughout much of the world, mostly due to deliberate introductions but also through natural dispersal and shipborne travel. It is quite successful, due to its adaptability and ability to easily co-exist with humans.

The Royal Spoonbill is a species of spoonbill found through much of the Australasia region. It lives in wetlands and feeds on crustaceans, fish, amphibians and small insects by sweeping its spoon-shaped bill from side to side through water.

The Superb Lyrebird (Menura novaehollandiae) is a pheasant-sized songbird endemic to Australia. At approximately 100 cm (39 in) long, it is the longest of all songbirds. The male (shown here) has a showy tail, with the two outermost feathers forming the shape of a lyre.

The Tasmanian Native-hen (Gallinula mortierii) is a flightless rail, one of twelve species of birds endemic to the Australian island of Tasmania, except the southwestern portion. Although flightless, it is capable of running quickly and has been recorded running at speeds up to 30 miles per hour (48 km/h). Fossil records indicate that the Tasmanian Native-hen was found on the Australian mainland until around 4700 years ago. Suggested reasons for its extinction there have included the introduction of the dingo, or an extremely dry period.

The Chestnut Teal (Anas castanea, male shown here) is an omnivorous dabbling duck found in southern Australia. The male has a distinctive green coloured head and mottled brown body. The female has a brown head and mottled brown body, which is almost identical to a female Grey Teal.

The Musk Lorikeet (Glossopsitta concinna) is a species of lorikeet found in south-central/eastern Australia. It grows to about 22 cm (9 in) long, and can be identified by its red forehead, blue crown and a distinctive yellow band on its wing.

This bird is also known as the crested seriema for the soft feathers that emerge from the base of the bill to form a fan-shaped crest.

A male (top) and female rusty-naped pitta (Hydrornis oatesi) in Mae Wong National Park, Thailand. This species of bird in the family Pittidae was described by amateur ornithologist Allan Octavian Hume in 1790. It is found in East and Southeast Asian subtropical or tropical moist lowland forests, montane forests, and bamboo forests.

A portrait of a ring-billed gull (Larus delawarensis) in Windsor, Ontario. The popular name of this medium-sized gull comes from the black ring around its bill. This species is found near lakes, rivers, or the coast in Canada and the northern United States. It nests in colonies on the ground, often on islands.

A malachite kingfisher (Corythornis cristatus) at Lake Baringo, Kenya. Although many male birds have brighter colours than females, this is not the case with the malachite kingfisher; both sexes are equally colourful. When fishing, these birds often perch less than a metre above the water, diving in once they spot fish, aquatic insects, or crustaceans to prey upon.

A pair of black lories (Chalcopsitta atra) at Gembira Loka Zoo in Yogyakarta, Indonesia. Described in 1786 by Giovanni Antonio Scopoli, this aptly named lory is found in eastern Indonesia. This species averages 32 cm (13 in) in length.

A male saffron finch (Sicalis flaveola), a species of tanager endemic to South America. Although frequently called a canary, the species is not related to the Atlantic canary. When nesting, the saffron finch typically makes use of cavities such as abandoned rufous hornero (Furnarius rufus) nests, bamboo branches, and the underside of house roofs. Males are polygamous, mating with two females during the nesting season.

A dusky lory (Pseudeos fuscata) at Gembira Loka Zoo in Yogyakarta, Indonesia. This species is endemic to New Guinea, where it lives in subtropical or tropical forests below heights of 2,500 metres (8,200 ft).

A female giant kingfisher (Megaceryle maxima) feeding on a tilapia on Lake Naivasha, Kenya. From left to right, this composite of four images illustrates: 1. the kingfisher returning to its perch with its prey; 2. smashing it against the post to break its spine; 3. holding it; 4. beginning to consume it.

A vervain hummingbird (Mellisuga minima) photographed at Strawberry Hill in Jamaica. This species, which can also be found in the Dominican Republic and Haiti, is the second-smallest bird in the world after the bee hummingbird. It has an average length of 6 cm (2.4 in), including the bill, and weight of 2–2.4 g (0.071–0.085 oz).

A female Eurasian bullfinch (Pyrrhula pyrrhula) photographed in Lancashire. This small passerine bird in the finch family was listed in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. It is breeds across Europe and temperate Asia, where it is mainly resident, though some birds may migrate. Birds of this species feed mainly on seeds and the buds of fruit trees.

A savanna hawk (Buteogallus meridionalis) from the Brazilian Pantanal. This species of large raptors is found in open savanna and swamp in Central and South America. It feeds on small mammals, lizards, snakes, crabs, and large insects.

The snowy owl (Bubo scandiacus) is a large, white owl of the typical owl family. Snowy owls are native to Arctic regions in North America and Eurasia. Males are almost all white (as seen here), while females have more flecks of black plumage. Juvenile snowy owls have black feathers until they turn white. The snowy owl is a ground nester that primarily hunts rodents and waterfowl and opportunistically eats carrion.

The griffon vulture (Gyps fulvus) is a Old World vulture in the bird of prey family Accipitridae. Specimens average 93–122 cm (37–48 in) long, with a 2.3–2.8 m (7.5–9.2 ft) wingspan. Like other vultures, the griffon vulture is a scavenger, feeding mostly from carcasses of dead animals which it finds by soaring over open areas.

The rock ptarmigan (Lagopus muta) is a medium-sized gamebird in the grouse family. Averaging 34–36 cm (13–14 in) long, with a wingspan of 54–60 cm (21–24 in), this species feeds primarily on birch and willow buds and catkins. The rock ptarmigan breeds across arctic and subarctic Eurasia and North America and commonly has up to six chicks.

Two yellow-billed oxpeckers (Buphagus africanus africanus) perched atop a zebra in Senegal. This bird is native to the savannah of Sub-Saharan Africa, where it feeds on insects and ticks, including the arthropod parasites found on large mammals, as well as blood. The species nests in tree holes lined with hair plucked from livestock, where it lays 2–3 eggs.

The European robin (Erithacus rubecula) is a small insectivorous passerine bird. Formerly classified as a member of the thrush family, it is now considered to be an Old World flycatcher. About 12.5–14.0 cm (5.0–5.5 inch) in length, males and females are similar in colouration, with an orange breast and face lined with grey, brown upperparts and a whitish belly; the orange breast emerges gradually after birth, as with the juvenile specimen shown here. The species is found across Europe, east to Western Siberia and south to North Africa; it is sedentary in most of its range except the far north. The unrelated American robin was named after it.

The black-tailed godwit (Limosa limosa) is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. There are three subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times. Its range stretches from Iceland through Europe and central Asia during the breeding season, wintering in areas as diverse as the Indian subcontinent, Australia, western Europe, and west Africa. The species is more likely to be found inland and on freshwater than the similar bar-tailed godwit. The world population is estimated to be 634,000 to 805,000, and the species is classified as Near-Threatened.

A portrait of a female bare-faced curassow (Crax fasciolata), taken at the Pantanal in Brazil. This species of bird in the family Cracidae is found in eastern-central and southern Brazil, Paraguay, eastern Bolivia, and extreme northeast Argentina. Its natural habitats are tropical and subtropical dry and moist broadleaf forests.

The nacunda nighthawk (Chordeiles nacunda) is a species in the nightjar family. It is endemic to South America, living in dry savanna, subtropical or tropical seasonally wet or flooded lowland grassland, and heavily degraded former forest. It is among the largest nightjars in the world, with a length of 27.5 to 32 cm (10.8 to 12.6 in).

The rufous-tailed flycatcher (Myiarchus validus) is a species of tyrant flycatcher endemic to Jamaica.

The yellow-billed shrike (Corvinella corvina) is a common resident breeding bird in tropical Africa, from Senegal east to Uganda, and locally in westernmost Kenya. It frequents forest and other habitats with trees. Although it generally feeds on insects, this shrike may hunt larger prey such as small frogs and mice.

The black-headed lapwing (Vanellus tectus tectus). It is a resident breeder across sub-Saharan Africa from Senegal to Ethiopia.

The Adélie penguin (Pygoscelis adeliae) is a species of penguin common along the entire Antarctic coast, which is their only residence. They are named after the French Antarctic territory of Adélie Land, which is in turn named for Adèle Dumont d'Urville. She was the wife of French explorer Jules Dumont d'Urville, who discovered these penguins in 1840. Adélie penguins are the most widely spread of the penguin species, and obtain their food by both predation and foraging. Their diet is mainly krill and fish.

Swallows, together with martins, form a family of passerine birds known as the Hirundinidae. They are found around the world on all continents, including occasionally in Antarctica. There are around 90 species of Hirundinidae, with the greatest diversity found in Africa, which is thought to be where they evolved as hole-nesters. For the most part swallows are insectivorous, taking flying insects on the wing and using foveae in their eyes to help track prey. This picture shows the pied-winged swallow, which is found in several countries in western Africa.

The blue petrel (Halobaena caerulea) is a small seabird in the family Procellariidae, the only member of its genus. It is distributed across the Southern Ocean but breeds at only six known sites, all close to the Antarctic Convergence zone. Its plumage is predominantly blue-grey, with an "M" banding across its top, which is similar to that of the closely-related prion. It also has a white-tipped tail. The blue petrel is 28 cm (11 in) in length with a wing span of 66 cm (26 in), and feeds predominantly on krill as well as other crustaceans, fish, and squid.

The roadside hawk (Rupornis magnirostris) is a relatively small bird of prey found in the Americas. A vocal species, it is often the most common raptor in its range. It has many subspecies, and although previously placed in the genus Buteo, it is now usually placed in the monotypic genus Rupornis. The roadside hawk is 31–41 cm (12–16 in) long and weighs 250–300 g (8.8–10.6 oz). Males are about 20% smaller than females, but otherwise the sexes are similar. This picture shows an immature roadside hawk in the Pantanal, Brazil.

The curlew sandpiper (Calidris ferruginea) is a small wader that breeds on the tundra of Arctic Siberia. It is a strongly migratory bird, wintering mainly in Africa, but also in Australia, New Zealand, and south and southeast Asia. The curlew sandpiper is similar to the dunlin, and has a length of 18–23 cm (7.1–9.1 in) and wingspan of 38–41 cm (15–16 in). In breeding season it has a bright red underside. This picture shows a curlew sandpiper in Thailand, with its winter plumage.

The common black hawk (Buteogallus anthracinus) is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. The mangrove black hawk, traditionally thought to be a distinct species, is now generally considered a subspecies, B. a. subtilis, of the common black hawk. This picture shows a bird of the Buteogallus anthracinus gundlachii subspecies, in Cuba.

The collared whitestart (Myioborus torquatus), also known as the collared redstart, is a tropical New World warbler endemic to the mountains of Costa Rica and western-central Panama. It is common at heights between 1,500 metres (5,000 ft) and the timberline in mossy mountain forests, ravines, second growth, and adjacent pastures. The collared whitestart is around 13 centimetres (5 in) in length with a weight of 10.5 grams (0.4 oz). It has a chestnut crown bordered with black, and a black forehead. The rest of the upperparts are slaty black, and the tail is black with white edges. The face and underparts are bright yellow, with a black band across the breast.

The bee-eaters are a group of near passerine birds in the family Meropidae, containing three genera and twenty-seven species. Most species are found in Africa and Asia, with a few in southern Europe, Australia and New Guinea. They are characterised by richly coloured plumage, slender bodies and usually elongated central tail feathers. All have long down-turned bills and medium to long wings, which may be pointed or round. Male and female plumages are usually similar. As their name suggests, bee-eaters predominantly eat flying insects, especially bees and wasps, which are caught in the air by flights from an open perch. The stinger is removed by repeatedly hitting and rubbing the insect on a hard surface. During this process, pressure is applied to the insect, thereby extracting most of the venom. This composite, taken in 2016, shows six bee-eaters of the genus Merops found in Africa. Clockwise from top left, the species depicted are the blue-cheeked bee-eater (M. persicus chrysocercus), the cinnamon-chested bee-eater (M. oreobates), the little bee-eater (M. pusillus pusillus), the white-throated bee-eater (M. albicollis), the swallow-tailed bee-eater (M. hirundineus chrysolaimus) and the European bee-eater (M. apiaster).

The Cuban green woodpecker (Xiphidiopicus percussus) is a species of bird in the family Picidae. It is the only species within the genus Xiphidiopicus and is endemic to Cuba. A distinctive, relatively small woodpecker of the general size and shape of a sapsucker, the Cuban green woodpecker occasionally appears crested, with bright olive-green overparts and yellow underparts. The nape and upper breast are bright red, with some black bases to feathers usually visible, with a black chin and throat; the crown is red in males and black with white stripes in females. Females are significantly smaller than the male and generally shorter-billed. Juveniles are generally duller in plumage, showing more barring and streaking below. It typically measures 21 to 25 cm (8.3 to 9.8 in) in length and weighs 48 to 97 g (1.7 to 3.4 oz). This picture shows a female X. p. percussus individual.

The black-bellied whistling duck (Dendrocygna autumnalis) is a species of whistling duck that breeds from the southernmost United States and tropical Central America to south-central South America. In the U.S., it can be found year-round in peninsular Florida and parts of southeast Texas, as well as seasonally in southeast Arizona and Louisiana's Gulf Coast. Since it is one of only two whistling duck species native to North America, it is occasionally just known as the "whistling duck" or "Mexican squealer" in the southern United States.

The pied kingfisher (Ceryle rudis) is a species of water kingfisher that is widely distributed across Africa and Asia. Originally described by Linnaeus in 1758, it has five recognised subspecies. Its black and white plumage and crest, as well as its habit of hovering over clear lakes and rivers before diving for fish, make it distinctive. Males have a double band across the breast, while females have a single gorget that is often broken in the middle. They are usually found in pairs or small family groups. When perched, they often bob their head and flick up their tail. This picture shows a female C. r. leucomelanurus individual.

The gentoo penguin (Pygoscelis papua) is a penguin species in the genus Pygoscelis, most closely related to the Adélie penguin and the chinstrap penguin. The earliest scientific description was made in 1781 by Johann Reinhold Forster with a reference point of the Falkland Islands. They call in a variety of ways, but the most frequently heard is a loud trumpeting which the bird emits with its head thrown back. The gentoo penguin is easily recognized by the wide white stripe extending like a bonnet across the top of its head and its bright orange-red bill. It has pale whitish-pink webbed feet and a fairly long tail – the most prominent tail of all penguin species. Chicks have grey backs with white fronts. As the gentoo penguin waddles along on land, its tail sticks out behind, sweeping from side to side, hence the scientific name Pygoscelis, which means 'rump-tailed'.

The red-banded fruiteater (Pipreola whitelyi) is a species of bird in the family Cotingidae. Its known range is restricted to the humid highland forests of the tepuis in the southeast of Venezuela and western Guyana. While likely present, it remains unconfirmed in adjacent parts of northern Brazil. The International Union for Conservation of Nature has rated its conservation status as being of "least concern". Uniquely among the fruiteaters, the underparts of the male are primarily grey. As suggested by its common name, the male also has a conspicuous red pectoral collar. The species grows to a length of about 16.6 cm (6.5 in). This picture is a lithograph of a female (top) and a male (bottom) red-banded fruiteater, produced by Dutch bird illustrator John Gerrard Keulemans in 1886 for an edition of the journal Ibis. The adult male has greyish-green upper parts with a distinctive long golden stripe that runs above the eye and round the ear coverts. The chin and belly are grey and there is a broad, orange-red chest collar, and yellowish-ochre under-tail coverts. The female has similar head markings, a yellowish patch at the side of the neck, and moss-green upper parts. There is no chest collar and the underparts are greyish-white, boldly streaked with black. The beak and legs are pinkish-grey; the male has an orange iris and the female's is ochre.

The crested myna (Acridotheres cristatellus), also known as the Chinese starling, is a species of starling in the genus Acridotheres native to southeastern China and Indochina. It is named after the tuft of feathers on its forehead that resembles a crest. The crested myna is typically found in open spaces near urban and agricultural areas. It is a popular cage-bird and, as a result, has been accidentally released in a few places outside of its usual range. For example, this species was introduced around 1890 into the Vancouver region of British Columbia, Canada. Like many starlings, the crested myna is omnivorous. It will eat a variety of food including worms, grub, grains, fruit, and even garbage. It is a highly beneficial bird to farmers as it predates on insects and does not attack crops. This picture shows a crested myna photographed in Osaka, Japan.

The Indian roller (Coracias benghalensis) is a member of the bird family Coraciidae, the rollers. It occurs widely from the Arabian Peninsula to the Indian subcontinent and is designated as Least Concern on the IUCN Red List. The bird is best known for the aerobatic displays of males during the breeding season. It is commonly found in open grassland and scrub forest habitats, and is often seen perched on roadside bare trees and wires, which give it a good view of the ground below where it finds its prey. Its diet consists mainly of insects such as beetles and grasshoppers, but also includes spiders, scorpions, amphibians and small reptiles. The largest population occurs in India, and several states in India have chosen it as their state bird. This picture shows an Indian roller of the benghalensis subspecies, photographed in Kanha Tiger Reserve in the Indian state of Madhya Pradesh.

The black-chested snake eagle (Circaetus pectoralis) is a large African bird of prey in the family Accipitridae. It resembles other snake eagles and was formerly considered conspecific with the short-toed and Beaudouin's snake eagles, to which it is closely related. As well as feeding on snakes, which may be swallowed while still alive, it feeds on lizards, small mammals, frogs and insects. It typically perches in an elevated position ready to swoop silently to capture its prey, before returning to its perch to eat. This picture shows a black-chested snake eagle swallowing a snake, photographed in Awash National Park, Ethiopia.

The snowy egret (Egretta thula) is a small member of the heron family, Ardeidae, native to the Americas, where it has a widespread distribution. The bird forages for fish, frogs, crustaceans, insects and worms in marshes and shallow water habitats, applying various techniques to persuade the prey to reveal itself. A sociable species, it often forages in mixed species groups, and nests in the company of other herons and egrets. The bill is specially adapted for probing and stabbing. This picture shows a snowy egret photographed at Las Gallinas Wildlife Ponds, near San Rafael, California.

The chinstrap penguin (Pygoscelis antarcticus) is a species of penguin that inhabits land masses in the Southern Pacific and Antarctic Oceans. The bird's black back and white underparts provide camouflage in the form of countershading when viewed from above or below, helping it to avoid detection by its predators, which include the leopard seal, the southern giant petrel, the brown skua and the south polar skua. The chinstrap penguin grows to a length of 68–76 cm (27–30 in) and a weight of 3.2–5.3 kg (7.1–11.7 lb), with the weight varying with the time of year. Males are greater in weight and height than females. This picture shows a chinstrap penguin photographed on Deception Island, in the Antarctic archipelago of the South Shetland Islands.

The Malayan banded pitta (Hydrornis irena) is a small woodland bird in the family Pittidae from tropical southeastern Asia, seen here in Si Phang Nga National Park, Thailand. Although common in parts of its range, its forest habitat is threatened by logging and conversion to agricultural land, and populations are also declining because of illegal collection for the cage-bird trade. Pittas are a popular group of birds among birdwatchers, due to their bright-coloured plumage and the relative difficulty of seeing these retiring birds in dark forest habitats.

The white-faced plover (Charadrius alexandrinus dealbatus) is a small shorebird, usually considered to be a subspecies of the Kentish plover. With a length of about 17 cm (6.7 in), it differs from the latter in having a thicker, blunter beak, white lores, paler crown and overparts, less black on the lateral breast patches and a larger white wingbar. The bird is found in south-eastern China, Vietnam, Thailand, peninsular Malaysia and Sumatra, and is partially migratory. Seen here on the mudflats of Laem Phak Bia in Thailand, the white-faced plover feeds on the foreshore, searching visually for prey then dashing forward to catch the animal or probe in the substrate with its beak. Its diet consists of small invertebrates such as insects and their larvae, spiders, molluscs, crustaceans and marine worms. Its breeding habits are not known.

The tropical kingbird (Tyrannus melancholicus) is a large tyrant flycatcher, growing to a length of about 22 cm (8.7 in). It feeds on insects, either catching them in flight, or gleaning them from the surface of foliage, and also eats some fruit. The birds remain in pairs all year round, and drive intruders from their territories, including birds much larger than them. It nests high in trees, usually in the fork of a branch, building a bulky, untidy structure. The female incubates the typical clutch of two to four eggs and the young fledge in about 18 days. Its breeding range extends from the southern United States to central Argentina, with birds near the northern and southern limits of the range being migratory. This picture shows a T. m. melancholicus individual in the Pantanal, Brazil.

The Indian vulture (Gyps indicus) is an Old World vulture native to India, Pakistan and Nepal. It has been listed as critically endangered on the IUCN Red List since 2002. The cause of the catastrophic reduction in their numbers has been identified to be the use by farmers of the veterinary drug diclofenac, a nonsteroidal anti-inflammatory drug which extends an animal's working life, but makes its carcase toxic to vultures if the drug was recently administered. The Indian government has banned the use of the drug, and it is hoped that the vultures will stage a comeback. This photograph shows a group of Indian vultures nesting on a tower of Chaturbhuj Temple in Orchha, Madhya Pradesh.

The black-necked stilt (Himantopus mexicanus) is a species of shorebird in the family Recurvirostridae, inhabiting wetlands and coastlines in North, Central and South America. Adults average about 36 cm (14 in) in length, with black-and-white plumage and a thin, straight, black bill. The legs are long and pink, and there is a white spot above the eye that distinguishes the species from the white-backed stilt. Seen here near Corte Madera, California, the black-necked stilt forages by probing and gleaning on mudflats, grassy marshes and lakesides, as well as in shallow waters near the shore; the diet consists mainly of insects and their larvae, crustaceans, other arthropods, mollusks, tadpoles and small fish. The species nests in colonies that may have several dozen pairs spread out loosely, with the birds defending an extensive perimeter around groups of nests, patrolling in cooperation with their neighbors.

The cliff flycatcher (Hirundinea ferruginea) is a species of bird in the family Tyrannidae, the tyrant flycatchers. Native to South America, it is found among mountain crags, cliffs and gorges. It is also found, particularly in the south of its range, around buildings in cities, where window sills and facades provide a form of artificial cliff. About 18.5 cm (7.3 in) in length, its rufous colouring and behaviour are distinctive. It has a wide beak and long pointed wings, resembling those of a swallow. The overparts are dusky brown, with a distinctive rufous rump and tail base. The tips of the wing feathers are dark, but the remaining parts are cinnamon-rufous, and are exposed in flight. The underparts are pale cinnamon-rufous, with some grey speckling on the throat. This picture shows a cliff flycatcher photographed in the municipality of Pindamonhangaba, in the Brazilian state of São Paulo.

The blue pitta (Hydrornis cyaneus) is a species of passerine bird native to tropical south-eastern Asia. It has long legs and a short tail, and is about 23 cm (9 in) long, the female being more sombrely clad than the male. Secretive and shy, it is found in moist lowland and montane forests, particularly in ravines and near watercourses. It forages on the forest floor for insects and other small invertebrates, flicking away leaves and probing the ground with its beak. The nest is a large, bulky dome-shaped structure with a side entrance, hidden amongst tangled plant growth. This picture shows a male blue pitta photographed in Khao Yai National Park, Thailand.

The marsh wren (Cistothorus palustris) is a small North American songbird of the wren family. The adult has a dark cap, brown upper-parts, a white throat and breast, and light brown underparts. It breeds in southern Canada and the United States; some birds are resident while others migrate to overwinter in the southern United States and Mexico. Its habitat is marshland where it nests in tall vegetation, the male building several oval structures with side entrances, only one of which is eventually used by the female. The male is fiercely territorial, attacking the eggs and young of other birds nesting in the vicinity. This photograph was taken in the Cap Tourmente National Wildlife Area in the province of Quebec, Canada.

The rufous-headed ground roller (Atelornis crossleyi) is a forest bird endemic to Madagascar. It is a distinctively coloured bird, about 25 cm (10 in) in length. Seen here in Ranomafana National Park, it is a secretive bird that stays deep in the forest, feeding on the ground on ants, cockroaches and beetles. It nests in a burrow in an earth bank. The species is listed by the International Union for Conservation of Nature as near threatened because it is hunted for food although it is present in a number of protected areas, and the forests in which it lives are threatened by slash-and-burn cultivation.

The Daurian redstart (Phoenicurus auroreus) is a small passerine bird from temperate Asia. The adult male has a grey crown and nape, a black face and chin, brownish mantle and wings and a large white wing patch; the chest, lower back and rump are orange, and the tail is black with orange sides. The female is brown above and paler brown below, with an orange rump and tail sides, and a large white wing patch similar to the male's. The species grows to a length of about 15 cm (6 in), and breeds in Manchuria, southeastern Russia, northeastern Mongolia, central China and Korea. A common migratory species, it is not considered to be a threatened species by the International Union for Conservation of Nature. This picture shows a male Daurian redstart photographed at Daisen Park in Osaka, Japan, in midwinter.

The Japanese pygmy woodpecker (Yungipicus kizuki) is a species of woodpecker native to coniferous and deciduous forests in Russia, China, North Korea, South Korea and Japan. With a length of about 140 mm (5.5 in), its plumage is a dark greyish-brown, barred and blotched with white, with pale brown, streaked underparts. The male has a small red mark on the side of its nape, which the female lacks. It usually occurs in pairs or mixed-species foraging flocks, searching on trees for invertebrates, such as spiders, caterpillars, ants and aphids, and berries. Breeding takes place in the spring, with the nest being in a hole excavated in a dead branch. This picture shows a Japanese pygmy woodpecker photographed in Sakai, in Osaka Prefecture, Japan.
