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.
The Ailuroedus catbirds are monogamous, with males raising chicks with their partners, but all other bowerbirds are polygynous, with the female building the nest and raising the young alone. These latter species are commonly dimorphic, with the female being drabber in color. Female bowerbirds build a nest by laying soft materials, such as ...

[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.
These nests have a unique chambered construction. [3] While many Furnariids have different nests, the hornero nest is the reason for the common name applied to the entire family; ovenbirds (they are unrelated to the parulid warbler called the ovenbird in the United States). The size and exact shape of the hornero nest varies depending on the ...
