Deep cup nest of the great reed-warbler. A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too ...
Other birds often built their own nests on top of Weaver nest sites. [4] Some birds build nests in trees, some (such as eagles, vultures, and many seabirds) will build them on rocky ledges, and others nest on the ground or in burrows. [3] Each species has a characteristic nest style, but few are particular about where they build their nests.
Amongst birds, 5% of all birds use mud and stones in their nest for toughness and compressive strength. [17] Males in some species of crab will construct structures out of mud to attract mates and avoid predators. [23] Uca musica, also known as fiddler crabs, will build short, wide “hoods” out of sand.

The complexity of bird nests varies markedly, perhaps indicating a range in the sophistication of tool use. For example, compare the highly complex structures of weaver birds [115] to the simple mats of herbaceous matter with a central cup constructed by gulls, and it is noteworthy that some birds do not build nests, e.g. emperor penguins. The ...

How do birds get their colors? Understanding bird coloration combines biology and physics. There are two primary ways that birds get their color: pigmentation and the physical structure of the ...
The bird's nesting hole requires not only the bird's making a hole but also the cactus's lining the hole - it is not ready for use as a nest until a year after its creation. [4] Many saguaros are home to multiple nests; if birds excavate adjoining hollows, a saguaro boot may be formed with more than one opening.
