These are vertebrate animals that live in every corner of our planet. Some aquatic species, such as the penguin, spend much of their time submerged in water.
Most birds can fly. However, there are non-flying species, such as ostriches, kiwis, and emu. Generally, the term birds are used to designate the smaller birds, for example, a goldfinch or a greenfinch.
We have a distinctive feature: they have feathers; this is independent of whether they fly, are land birds or water birds. Their diet is very varied.
Two wings, in arm position, which are appropriately adapted for flying. The birds have the characteristic of having a hollow and specially hardened bone, adapted to lighten their body and, therefore, fly.
The birds’ reproduction is through eggs, which must be previously fertilized; the birds form nests, where they lay their eggs, and then sit on them so that their high temperature allows them to hatch. For this function, in some species, both the male and the female sit to hatch them.
A strange phenomenon occurs in the birds’ bodies. Their feathers become fluffy, and their temperature rises above what it usually is so that their temperature helps the hatching of the chicks.
Birds reproduce by internal fertilization. It is striking that during the breeding season, they perform a series of rites, such as the male’s courtship to mate with the female or the nests’ construction.
The birds lay eggs provided with a hard calcareous cover (the shell) that incubate until its manifestation. Once the eggs hatch, the chicks will depend for a time on the care of their parents.
Birds live in all land areas and all oceans of the world. They are even found in the Antarctic region.
Generally, birds migrate to take advantage of the seasonal differences in temperature around the world. Migrations vary significantly according to the genus.
