Brown-headed cowbirds

Description:

The Brown-headed Cowbird is typical for an icterid in general shape but is distinguished by a finch-like head and beak and is smaller than most icterids. The adult male is iridescent black in color with a brown head. The adult female is slightly smaller and is dull grey with a pale throat and very fine streaking on the underparts. The total length is 16–22 cm (6.3–8.7 in) and the average wingspan is 36 cm (14 in). Body mass can range from 30–60 g (1.1–2.1 oz), with females averaging 38.8 g (1.37 oz) against the males' average of 49 g (1.7 oz). (information from Wikipedia)

Habitat:

Open lot in a strip mall in Frisco, TX.

Notes:

This was a large congregation of birds, and while I'm positive there had to be other species mixed in, the vast majority that I could identify were brown-headed cowbirds.
