The Orchard Oriole (Icterus spurius) is the smallest North American species of icterid blackbird. The subspecies of the Caribbean coast of Mexico, I. s. fuertesi, is sometimes considered a separate species, the Ochre Oriole.
This species is 6.3 in (16 cm) long and weighs 20 g (0.71 oz). The bill is pointed and black with some blue-gray at the base of the lower mandible (Howell and Webb 1995). The adult male of the nominate subspecies has chestnut on the underparts, shoulder, and rump, with the rest of the plumage black. In the subspecies I. s. fuertesi, the chestnut is replaced with ochre (Howell and Webb 1995). The adult female and the juvenile of both subspecies have olive-green on the upper parts and yellowish on the breast and belly. All adults have pointed bills and white wing bars. (Orchard Orioles are considered to be adults after their second year.) One-year-old males are yellow-greenish with a black bib.
