A male house wren can claim a nesting cavity by filling it with more than 400 small twigs. If the female likes what she sees, then she will take over, adding the cut to the nest and lining it with grass, inner bark, hair and feathers.

The American robin will use mud in its nest to give it strength. You can put in a small pot of mud and nesting material (short ropes, threads, and dry grasses) and watch the robins come and collect materials to make their nests. Unlike most birds, robins do not lay their eggs at sunrise. They lay their eggs several hours later in the middle of the morning. Since earthworms are easier to find early in the morning, they feed early in the morning and then return to their nests to lay their eggs.

Mourning dove nests are sticks woven together by the female with materials collected by the male. Mourning doves can have up to six clutches per year, with a typical clutch size of two eggs. This is the highest number of nesting cycles of any North American bird.

Hummingbirds use cobwebs as a glue to attach the nest to a tree branch, as well as a binder for building materials. The nest is about the size of a golf ball, about 11/2 inches in diameter.

Goldfinches are one of the newer songbirds, waiting to nest until mid to late summer when thistle seeds and down are readily available.

The red-breasted nuthatch will line the entrance to its nesting cavity with drops of sticky coniferous resin. It is believed that this may be a tactic to deter predators or nest competitors from entering.
