McGILL BIRD OBSERVATORY |
||||||
HY female Baltimore Orioles are paler than all other age/sex classes, often with a grayish tinge to the head and/or back. There can be considerable overlap in the appearance of HY males and females; checking wing chord (females <91 mm, males >91 mm) is advisable.
The wing of HY females is generally a dull dusky colour with white edging on some feathers, and is rarely distinguishable from that of HY males.
The tail of HY females is usually comprised of narrow and tapered feathers, dull brown with some orange tinges.
