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 ...
Sociable weavers construct permanent nests on trees and other tall objects. These nests are amongst the largest built by any bird, and are large enough to house over 100 pairs of birds, [10] containing several generations at a time. The nests are highly structured and provide birds with a more advantageous temperature relative to the outside.
A chick of the common cuckoo in the nest of a tree pipit. The naked, altricial chick hatches after 11–13 days. [2] It methodically evicts all host progeny from host nests. It is a much larger bird than its hosts, and needs to monopolize the food supplied by the parents.
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 greater honeyguide is known to guide people to the nests of wild bees. [3] [4] A guiding bird attracts a person's attention with wavering, chattering " 'tya' notes compounded with peeps or pipes", [5] sounds it also gives in aggression. The guiding bird flies toward an occupied nest (greater honeyguides know the sites of many bees' nests in ...
This behaviour is unusual for terns, which generally nest on the ground, and even the related tree-nesting black noddy constructs a nest. It is thought that the reason for the absence of nests is the reduction in nest parasites, which in some colonial seabirds can cause the abandonment of an entire colony. [16]
Most species weave nests that have narrow entrances, facing downward. Many weaver species are gregarious and breed colonially. [2] The birds build their nests together for protection, often several to a branch. Usually the male birds weave the nests and use them as a form of display to lure prospective females.
Their cup nest is built in the fork of a tree, [8] often a smooth-boled tree with an isolated canopy, The nesting pair may even remove bits of bark on the trunk to make it smooth. [29] The usual clutch is three to four eggs. The eggs are creamy white with blotches of reddish brown which are more dense at the broad end. [15] In flight, at ...
