BROWN HEADED COWBIRDS, 2: Whether you call 'em 
cowbird or bison bird, the destruction they cause is the 
same...details on Passport to Texas

This is Passport to Texas Supported by the WSFR Program

Calling a brown-headed cowbird a cowbird, is a misnomer 
as far as biologist Marsha May is concerned. 

I think they should be called bison birds, and not cowbirds, 
because they evolved with the bison. :05

Semantics aside, the bird's habit of laying its eggs in other 
birds' nests can cause the decline of species with small 
populations, such as the endangered Black-capped Vireo. 
Additional species are also affected. 

Woodland species are now being impacted by brown-headed 
cowbirds, because we've fragmented the woods. Previously those 
woodland species were protected by the woods. Now that it's 
fragmented, the cowbirds are getting into that habitat, and they're 
parasitizing birds that have never historically been parasitized 
before. :19

The cowbird is in the blackbird family. The male has a 
black body and brown head, while the female is mottled 
brown and gray. Want to intervene on songbirds' behalf.

You can actually become certified in Texas to trap for cowbirds, 
and that's mainly during the breeding season, between March first 
and May thirty-first. And, mainly you're trying to trap the females.
