A female
Common Blackbird (
Turdus merula) in her
nest. Cup nests like the one shown here, usually made of pliable materials like
grasses, are commonly built by
passerines. Other types of nests include the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, or a mud dome with an entrance tunnel.
