These birds forage at night, catching insects in flight, and normally sleep during the day. Eastern whip-poor-wills nest on the ground, in shaded locations among dead leaves, and usually lay two eggs at a time. The bird will commonly remain on the nest unless almost stepped upon. [citation needed] The whip-poor-will has been split into two species.
The pied mutation first appeared in California in 1949. This mutation is a blotch of colour on an otherwise solid-coloured bird. For example, this may appear as a grey blotch on a yellow cockatiel. Lutino colouration was first seen in 1958. These birds lack the grey of their wild counterparts and are white to soft yellow.
The behavior spreads among the birds by imitation. [11] In captivity some will spontaneously dance to music with a variety of unique moves. [12] These birds are very long-lived, and can live upwards of 70 years in captivity, [13] [14] although they only live to about 20–40 years in the wild.

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 ...
The nest is hammock-like and suspended from the underside of a leaf using 150 or so "pop-rivets" of cobwebs and vegetable fibre, a unique method of using spider silk for animal architecture. [ 18 ] It is suspected that Hodgson's hawk-cuckoo and violet cuckoo are brood parasites on this species in India.
The larger American robin (Turdus migratorius) is a much larger bird named from its similar colouration to the European robin, but the two birds are not closely related, with the American robin instead belonging to the same genus as the common blackbird (T. merula), a species which occupies much of the same range as the European robin. The ...
For a lone potoo, or a brooding adult with a potential predator close to the nest, the bird attempts to avoid detection by remaining motionless and relying on camouflage. If ineffective, the potoo breaks cover and attempts to intimidate the predator by opening its beak and eyes wide open while vocalizing or simply flies out of reach.
