Baltimore Oriole USA

Baltimore Oriole

The Baltimore Oriole (Icterus galbula) is a small icterid blackbird that commonly occurs in eastern North America as a migratory breeding bird. This bird received its name from the fact that the male's colors resemble those on the coat-of-arms of Lord Baltimore. Like all icterids called "orioles", it is named after an unrelated, physically similar family found in the Old World: the Oriolidae.
This medium-sized passerine measures 17–22 cm (6.7–8.7 in) in length and spans 23–32 cm (9.1–13 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 1.5 oz). The male oriole is slightly larger than the female, although the size dimorphism is minimal by icteridstandards. Adults always have white bars on the wings. The adult male is orange on the underparts shoulder patch and rump, with some birds appearing a very deep flaming orange and others appearing yellowish-orange. All of the rest of the male's plumage is black. The adult female is yellow-brown on the upper parts with darker wings, and dull orange-yellow on the breast and belly.The male sings a loud flutey whistle, with a buzzy, bold quality, and a belovedly familiar sound in much of the eastern United States. The male typically sings from the tree canopy and his song often gives away the bird's location before any sighting can be made. Advertisement
