Baltimore Oriole
Icterus galbula
This medium-sized passerine measures 17–22 cm (6.7–8.7 in) in length and spans 23–32 cm (9.1–12.6 in) across the wings. Their build is typical of icterids, as they have a sturdy body, a longish tail, fairly long legs and a thick, pointed bill. The body weight averages 33.8 g (1.19 oz), with a range of weights from 22.3 to 42 g (0.79 to 1.48 oz). The male oriole is slightly larger than the female, although the size dimorphism is minimal by icterid standards. Adults always have white bars on the wings. Voice: The Baltimore orioles' song is a short set of recognizable, sweet whistles that sound like "tyew, pyeer, peededoo, and "teer." Calls include "veeer," which is an unusual nasal sound, a low chatter call, and two high calls which sound like "tyew-li and kleek.
