Scientific Name: Icterus cucullatus
Population Estimate: 600K
Range / Habitat: From southwestern US into Mexico and Belize in lowland subtropical and tropical dry forest.
Field Notes: The nelsoni subspecies (top photo) is more yellowish, with a scalloped bar across the back, more white in the wings and less extensive black (stops before base) in the tail. The Yucatan subspecies (igneus, shown below) is more orange than others throughout Mexico. Though you can't fully see the black mask and bib in the second photo, it shows the characteristics that distinguish it from other sympatric orioles: black bar across the back (which Orange Oriole lacks) and first wing bar white (not orange as on the Altamira Oriole).
