Field Marks and
Identifying Characteristics:
Brownish gray overall. Wings and back darker then the underparts. Stocky looking seed eater with large dark conical bill and somewhat flat looking crown. Prominent red iris really stood out on bird. The tail did look relatively short on the bird compared to the Brown-headed Cowbirds that were also present.

Similar species and how
were they eliminated:
The easily seen red iris. Plus the shape, color and size of the bill made it difficult to mistake it for any other cowbird or bird.

this & similar species:
I have seen them a couple other times in Utah and many times in California and Arizona.
