McGILL BIRD OBSERVATORY |
||||||
SY female Baltimore Orioles can be separated from other ages and sexes by having a largely yellow head with minimal black spotting, and a dull golden-brown back. Often, as in the photo below, conspicuous molt limits on the wing can also be seen while the bird is perched.
SY Baltimore Orioles typically show conspicuous molt limits on the wings, most commonly within the greater coverts. This is illustrated by the photo below, where the majority of greater coverts have been replaced (dark brown to black with distinct white tips) while the outermost one or two greater coverts remain old (brown and worn, with minimal edging). Also, the primary coverts are brown and unreplaced, whereas in ASY females they would be dark brown.
Female Baltimore Orioles have yellow to brown tail feathers. In SY females, the outermost rectrices in particular tend to be tapered and abraded; sometimes the tips are frayed, as in the photo below.
