Different birds build their nests in different ways because
Answers
A bird nest is a place where a bird lays its eggs. There are all kinds of nests, including cup nests, holes in the ground, and piles of twigs and leaves.
The word can be used as a noun or a verb, as in – a bird nests in a nest. They are in all kinds of sizes: some can be as big and heavy as a car, like an old eagle's nest, while some can be tiny as a thimble, like the nest of a Bee Hummingbird.Usually, the female builds the nest, and the male helps her. In some species, though, the male does nothing, and in others, the male builds the nest and the female does nothing.
Many birds "glue" their nests together with materials like spider webs, silk, mud, and even their own saliva (spit). Most nest builders like to put soft things inside their nest. Some birds even put herbs and spices in their nest. Scientists think these herbs help fight off bacteria in a way they can't completely understand yet.The majority of birds build some type of nest in order to lay their eggs and rear their young chicks.
Depending on the bird, the nest may be large or small. It may be located in a tree, on a building, in a bush, on a platform over the water, or on the ground, and it may be made of mud, dried leaves, reeds, or dead trees.
1. Scrape Nests:
The scrape nest represents the simplest type of nest that a bird can build. It's typically just a scrape in the ground that makes a shallow depression for the birds to lay their eggs.
The rim of a scraped nest is just deep enough to keep the eggs from rolling away. Some birds may add stones, feathers, shells, or leaves to the scrape.
Scrape nests are made by ostriches, tinamous, shorebirds, gulls, terns, falcons, pheasants, quail, partridges, bustards, nighthawks, vultures, and a few other species.
2. Burrow nests:
Burrow nests are shelters within trees or the ground that act as safe havens for birds and their developing young. Birds use their beaks and feet to carve out their burrows. Most birds create their own burrows, but some—such as burrowing owls—prefer to use those created by others.
This type of nest is commonly used by seabirds, especially those that live in colder climates as a burrow nest can offer protection from both predators and the weather. Puffins, shearwaters, motmots, kingfishers, miners, the crab plover, and leaf-tossers are all burrow nesters.
3. Cavity nests:
Cavity nests are chambers found most often in trees - living or dead - that certain birds will use to raise their chicks.
Only a few bird species—such as woodpeckers, nuthatches, and barbets—are capable of excavating their own cavity nests.
These birds are considered primary cavity nesters. But the majority of cavity nesters—birds like some ducks and owls, parrots, hornbills, and bluebirds—use natural cavities or those that were created and abandoned by another animal.
Hence, these are the different types of bird nests.
