If we need to outline birds strictly, we’d say they’re warm-blooded, bipedal vertebrate animals, with forelimbs developed into wings, lined in feathers and with a beak instead of a mouth.

After a parasitic bird lays her eggs in one other fowl’s nest, they’re often accepted and raised by the host on the expense of the host’s personal brood. One hundred bird species, together with honeyguides, icterids, and geese, are obligate parasites, though essentially the most well-known are the cuckoos. These species pair for no less than the length of the breeding season or—in some instances—for a number of years or till the death of 1 mate.
