Bird Bird colours Bird camouflage
 Many birds are brown, green or grey. Brown is the most common colour. Brown birds include sparrows, emus, thrushes, larks, eagles, falcons and the female birds of many species such as wrens, ducks, blackbirds and peacocks. When a brown bird is in long grass or among tree trunks or rocks, it is 'camouflaged'. Birds that live in long grass often have brown feathers streaked with black which looks like shadows. A Bittern is almost invisible in long reeds.
