Most birds nest their eggs. The material from which nests can be constructed depends on the species of bird and the materials available in the area. Robins and eagles are both well known species that nest their eggs.
No. Some birds nest on the ground (curlews), some (woodpeckers) make holes in trees and some lay their eggs in other birds nests (cuckoos).
Probably none. Birds generally build their own nests. It makes them feel safe.
No, Song Wrens are monogamous birds, and only the female of the mating pair will lay eggs in the nest. However, both parents will typically help incubate the eggs and care for the chicks once they hatch.
I believe some species of birds steal others birds eggs and raise them as their own but I suggest you look up purple finches on the internet or a book and read about them laying eggs to be sure. I've never heard of birds stealing other eggs and brooding them but what I do know for sure is that the Brown Headed Cowbird does not make it's own nest and lays its eggs in other birds nests. The Cowbird is actually considered a parasite in that it's eggs will hatch first and dominate the nest. In some circumstances some of the intended hatchlings could starve to death or be killed by the young Cowbirds. Simply remove the brown spotted eggs.
I am not sure about the amount of eggs.... most likely 4-5 eggs, but some birds lay eggs in nests of other birds when they have hatched their eggs and are done raising their chicks.
The entire process from the time the mother bird lays the eggs until the baby birds leave the nest varies depending on the species of bird. Some birds like hawks and herons keep the babies around longer than other birds like hummingbirds.
Eggs are laid by female birds, reptiles, amphibians, and fish. They are usually laid in nests or in a safe location where the parent can protect and incubate them until they hatch. Some species of animals, like birds, have specially constructed nests in which they lay and incubate their eggs, while others may lay their eggs in soil or water.
I just found some in my garage and I'm pretty sure its the heat from the weather and they lay on a nest kinda looks like a birds nest and there were a lot of eggs some hatched some not they were in a desk drawer close to a open window.
Some birds do not build nest's .why?
It is often said that if you touch a bird's eggs or nest or the nestlings, the mother bird will abandon the nest. But, this is really not the case. That myth has been told for a very long time but, if you are careful, and do not overly disturb the nest, you will not cause the nest to be abandoned if you replace a fallen nestling in the nest or help the birds in some other way. There are, however, other reasons not to touch wild bird eggs, nests, or the birds themselves and those are to protect you from bacterial or viral diseases that may be carried on the feathers of the birds or on the nest and egg shells. You should never touch a dead bird with bare hands and always wash your hands well with soap and water immediately after any contact with areas that may be contaminated by birds or their feces.
Nests are simply used as nurseries. Birds do not stay in a nest once the babies are old enough to live on their own. Birds live in trees and bushes. Females only stay in a nest if there are eggs or little ones.
Birds in Antarctica often nest on the bare ground, rocky ledges, or in shallow burrows dug in snow or soil. Some species will build nests with pebbles or stones to protect their eggs and chicks from the harsh environment.
