*Aging Rusty Blackbirds in the fall is a fairly easy task. Adults should have white/yellow eyes, and hatching-year birds should have mostly brown eyes. In fall, Male RUBLs (pictured today) tend to be darker with less "rust" on the edges of their feathers, and have a blue-green iridescence or gloss to the majority of their black feathers (especially the wing feathers). Fall Female RUBLs have noticeably more "rust" throughout their body feathers (especially the face) with an obvious pale eyebrow, and lack any gloss to their dark gray-black body feathers, which appear more matte or flat.
Mostly all of the rusty edging on the feathers will wear away during winter, and by spring, returning Rustys will be entirely black.
