Baltimore Oriole (Icterus galbula) [XC407924]
by Christopher McPherson from Watts Flats WMA, New York (near Ashville), Chautauqua County, New York, United States (song)
DNA data indicate that this is sister-species of Black-backed / Abeille's Oriole (Icterus abeillei). Formerly treated as conspecific with Black-backed / Abeille's Oriole (Icterus abeillei) and with Bullock's Oriole (Icterus bullockiorum). Hybridizes extensively with Bullock's Oriole (Icterus bullockiorum) in a belt from southern Canada (Alberta and Saskatchewan) southern in Great Plains to southern USA (Oklahoma and Texas), but assortative mating (or selection against hybrids) evident at several locations.
