The Baltimore oriole has one of the largest ranges of all of the Icterus. There breading range stretches across most of the eastern United States and stretches up into central Canada. Theeir range overlaps the bullocks oriole in the central portions of North America. The two species where once considered one species called the northern oriole, mostly because of extensive hybridization where the ranges cross, but DNA testing in the 1990's led to the separation of the two species. One of the cool things of most of the orioles is their nest. The female builds a sock like nest that hangs down from the branches. The female above was in the process of building her nes when I photographed her.The top photo is a male, which have a deeper orange color and black head during the breeding season.
