Streak-backed Oriole

Overview

The Streak-backed Oriole is a bright orange oriole found from western Mexico to Costa Rica, named for the distinctive black streaking across its back, which sets it apart from similarly colored orioles with plain or solid-black backs. It occasionally strays north as a rare vagrant to the southwestern United States.

Feather Identification

• Body feathers: Bright orange overall, including the head and underparts
• Back feathers: Orange background streaked with black, a distinguishing feature among orioles
• Throat feathers: Black bib, variable in extent between individuals
• Wing feathers: Black with white wing bars
• Similar species: The streaked back separates this species from Hooded Oriole (plain black back) and Altamira Oriole (solid black back with orange shoulder patch)

Plumage Details

Adults show bright orange plumage on the head and underparts, with the back showing a distinctive mix of orange and black streaking rather than a solid color. A black throat bib is present, variable in size among individuals and populations. Females are similar to males but often slightly duller. Juveniles are paler and show less defined streaking and bib until subsequent molts.

Habitat & Range

Streak-backed Orioles are found in dry forests, thorn scrub, and woodland edges from western Mexico south through Central America to Costa Rica. The species is generally resident, though individuals occasionally wander north as rare vagrants to the southwestern United States.

Behavior & Field Notes

Streak-backed Orioles forage for insects, fruit, and nectar in trees and shrubs. Their song consists of varied whistled and chattering phrases. They build woven hanging nests suspended from tree branches, similar in general form to other New World orioles.
