Brown-headed Cowbird

The Brown-headed Cowbird is a small blackbird famous for its obligate brood parasitic behavior, meaning it lays its eggs in the nests of other bird species rather than building its own. Males have glossy black bodies with contrasting dark brown heads, while females are a plain, uniform grayish-brown.

Uniform dark brown to grayish-black coloration without distinct barring or streaking, typical of a female or juvenile Brown-headed Cowbird.

Pennaceous upper vane with tightly interlocked barbs, transitioning to a somewhat plumulaceous or fluffy structure near the base with a small afterfeather.

Slender, flexible central rachis matching the dark brown tone of the vane, with uniform barb density along its length.

Smooth, silky, and relatively soft with a matte finish, typical of small passerine contour feathers.

Body feather, likely from the breast, flank, or back, determined by its size and contour shape.

Uniform grayish-brown coloration, small size characteristic of icterids, and smooth pennaceous vane structure.

Open and semi-open country, agricultural fields, brushy edges, and shortgrass prairies.

Widespread across North America, breeding from southern Canada through the United States to Mexico, with northern populations migrating south for the winter.

Acts as a brood parasite impacting host bird populations, though it is a native species playing a natural role in North American ecosystems.

Other blackbird females or small dark passerines, distinguished by exact shade of brown and geographic context.

Brown-headed Cowbirds parasitize the nests of over 200 different species of birds, tricking host parents into raising their larger and often more aggressive chicks.

Has no significant historical or traditional use in commercial trade; feathers are strictly studied for ornithological purposes.

Look near fields, forest edges, and livestock areas where cowbirds frequently forage on the ground.

Good condition, mostly intact barbs with minor wear at the base, grade is Good.
