The young birds are able to fly and are totally independent. They must find food and defend themselves from predators such as monitor lizards , reticulated pythons , wild pigs , and cats. The maleo is monogamous and members of a pair stay close to each other all the time.
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 ...
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.
A so-called "cathedral" mound produced by a termite colony. Structures built by non-human animals, often called animal architecture, [1] are common in many species. Examples of animal structures include termite mounds, ant hills, wasp and beehives, burrow complexes, beaver dams, elaborate nests of birds, and webs of spiders.
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 ...
Like its relatives, jackdaws are intelligent birds, and have been observed using tools. An omnivorous and opportunistic feeder, it eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. Western jackdaws are monogamous and build simple nests of sticks in cavities in trees, cliffs, or buildings. About ...

The typical nest is a grass or feather-lined deep closed mud bowl with a small opening at the top, [12] but many Asian house martins leave the top of the nest open. [ 20 ] [ 21 ] [ 22 ] David Winkler and Frederick Sheldon believe that evolutionary development in the mud-building swallows, and individual species follow this order of construction.
