Was at the North Tract of the Patuxent Refuge this AM and saw two blackbirds at the north end of Lake Allen. Got pretty good look- long bills, yellow eye, glossy black. They looked like Rusty BBs, but had no rust. Could they be pre-molt birds or birds that have already lost their rust? The light wasn't good enough to see if they had purlpe or greenish sheen. What else would differential Rusty & Brewer's. How close are the two bill sizes. These birds seemed to have farily long bills.
