The birds are best known for building massive nest mounds of decaying vegetation, which the male attends, adding or removing litter to regulate the internal heat while the eggs develop. However, some bury their eggs in other ways; there are burrow-nesters which use geothermal heat, and others which simply rely on the heat of the sun warming the ...
The cockatiel is the easiest cockatoo species to maintain and is by far the most frequently kept in captivity. White cockatoos are more commonly found in captivity than black cockatoos. Illegal trade in wild-caught birds contributes to the decline of some cockatoo species in the wild.
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 nests are located in rock crevices, in caves, under cliff overhangs or on buildings. [44] The eastern rock nuthatch builds a similar but less complex structure across the entrance to a cavity. Its nest can be quite small but may weigh up to 32 kg (70 lb). This species will also nest in river banks or tree holes and will enlarge its nest ...
It was found that nests close to cuckoo perches were most vulnerable: multiple parasitised nests were closest to the vantage points, and unparasitised nests were farthest away. Nearly all the nests "in close vicinity" to the vantage points were parasitised. More visible nests were more likely to be selected by the common cuckoos.

This colony is made up of 300 to 600 wild birds that make use of the trees within the artificial islands inside the zoo. [29] Another colony of 26-96 nests is known from the Sultanpur National Park in Haryana, India where years with increased rainfall see more storks nesting. [43]
