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 ...
A nest is a structure built for certain animals to hold eggs or young.

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.

These nests are constructed out of mud and are formed into a deep cup that is built on rock surfaces, typically in caves or on cliffs. Two eggs are laid twice a year. Though the birds breed in colonies, infanticide exists in this species, with rockfowl attempting to kill the young of other pairs. Nestlings mature in about a month.
