Question:

The U.S. strategy of mystery specific poultry is based on a now obsolete way of life. Can you tell me what this improvement strategy and how this species adapts well to his life story? What animal is the lifestyle necessary? Can you identify the taxonomic family of birds and species?

answer:

is an adult female Brown-headed Cowbird,

Molothrus ater . Thrush can be easily distinguished from other blackbirds by its shorter tail, heavier bill, like the lark. As you can see from this photo, Brown-headed cowbirds women are birds with black eyes and light brown with paler underparts with streaks -. Bacon women much less than red-winged blackbirds, which can be confused with

brown-headed cowbirds

belongs to the family Icteridae of taxonomy. In addition to the thrushes (genus,

Molothrus

), this taxon includes the Bobolink, larks, blackbirds, orioles, caciques and blackbirds, and New World Orioles - none of which are near the blackbirds of the Ancient World

• Turdus merula
• (thrush) or Old World Orioles, Oriolidae.

cowbirds

are social, often travel in large groups with open or semi. They feed mainly on seeds and insects caused by the grazing of large ungulates. However, before the Europeans and their pets have invaded North America, cowbirds followed herds of bison on the prairies. As a result, were less common today, as the clearing of forests for agriculture and livestock expanded open areas that are so favored by these birds are very common today, are all American North in the fields, pastures, lawns, golf courses, suburban lawns, parks and forest edges, and many make their living by visiting the bird feeders in the yard.

In keeping with their nomadic lifestyle, brown-headed cowbirds could not build nests and raise young people and forcing them to settle in one place - the buffalo did not. As a result, has developed a smart strategy to play: they have become parasites of bird's nest nesting species and raise their chicks. Interestingly, this behavior has evolved in the common Old World Cuckoo related

Cuculus canorus

, but apparently for different reasons - the brood parasites anyone know why cuckoos are?
released from the physical demands of nest building, incubation and breeding features chicken, brown-headed cowbirds women produce up to three dozen eggs per season. Unfortunately, because cowbirds have expanded their range very quickly, other species of birds now in contact with have not developed a defense against thrush chicks increased in preference to their own, a situation that contributes to the pursuit decline of these species.
