the nests of birds are not all......
Answers
Answer:
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 restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere 2 cm (0.8 in) across and 2–3 cm (0.8–1.2 in) high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than 11 m (36 ft) in diameter and stand nearly 5 m (16 ft) tall. The study of birds' nests is known as caliology.
Explanation:
The nests of birds are not all alike.
Bird's nests
Birds rest in nests to stay safely and lay eggs and breed. Different types of birds use different materials like twigs, sticks, thread, leaves, and other things. Similarly, different birds build nests at different locations and heights.
Like weaver birds build on thorn trees while tailor birds build by sewing down leaves together. The main reason for various adaptations of birds' nests is to protect their eggs and young ones from other animals and humans attacking them.
