Aves, Birds


[R] Terrestrial and homeothermic (body temperature maintained at a constant level) vertebrates with fore limbs modified into wings and body covered with feathers.
Birds lay eggs which they generally incubate. On hatching from the egg, young either leave the nest (i.e. are nidifugous) or are provided with food by their parents until they become independent (i.e; are nidicolous).
Many kinds of birds feed on insects and other pests of crops and are, therefore, beneficial.
However, granivorous, herbivorous and frugivorous birds feeding on crops are also a nuisance.
Among the birds notorious for the depredations they do rank the wood pigeon (Columba palumbus), the carrion crow (Corvus corone), the rook (Corvus frugigelus), the magpie (Pica pica), the goldfinch (Carduelis cannabina), the greenfinch (Carduelis chloris), the blue tit (Parus coeruleus), the house sparrow (Passer domesticus) and the starling (Sturnus vulgaris).
