One of the experts provided a link to a very good article with photos, "Rusty Blackbird Visual Identification Tips For Spring Migration".
The Rusty Blackbird I saw looked like the one pictured on the lower left of the article's first page.

RustyBlackbird.org is the nicely done website of the International Rusty Blackbird Working Group. The group focuses primarily on gathering and collecting information critical to developing on-the-ground conservation strategies and management programs to overturn the rapid decline of this species. There's plenty of information there, including a photo gallery.
