A few hatch-year (ie, juvenile) male Brewer's Blackbirds acquire
extensive brownish tipping to the feathers of the head, back and
breast after molting into first-basic (ie, first-winter) plumage. At
that time, they can look fairly similar to a fall Rusty Blackbird.
They are separated from Rusty's by their thicker-based bills and
lack of rusty edgings to the tertials and greater coverts.
