Audubon Turpiyalı Icterus graduacauda

Entirely yellow body with greenish back and black hood. Young birds slightly paler than adults; they develop black hood within a couple months of hatching. Tends to be more secretive than other orioles. A Mexican species with limited U.S. range. Most similar to Scott's Oriole but note greenish, not black, back; range does not overlap. Found in wooded habitats with dense brushy undergrowth. Sometimes visits feeders for fruit and seed. Song a slow series of low-pitched whistles.
