In the United States, the Streak-backed Oriole (Icterus pustulatus) has been reported primarily as a casual fall and winter visitor to southern Arizona and southern California. Its main range extends from the western lowlands of Mexico south to Costa Rica in Central America (American Ornithologists’ Union 1983). In the Mexican state of Sonora, it nests in tropical thorn scrub and deciduous forests (especially riparian), north to about latitude 30° N. The northernmost known nest was found about 175 km south of the international boundary at Félix Gómez (S. Russell and Monson, unpubl. manuscript).
