Northern Virginia, USA, Rusty vs. Brewer's Blackbirds (1 Viewer)

[gsimonel]

Is it possible to distinguish between a Brewer's and a rusty blackbird in this photo that I took earlier today? The beak looks more like a Brewer's, but there's no iridescence, and the location, a wooded, marshy area near the Potomac River, suggests that a rusty blackbird is more likely.

This is a Rusty blackbird, you can see whats left of the rusty colouration.
