Scientific name: Icterus spurius
The Orchard Oriole is often found in riparian areas and along shorelines. It is sometimes described as a semi colonial nester because nests within different territories can be quite close together. There is little evidence for winter territoriality in Orchard Orioles, and many individuals often roost together at night during winter months.
Orchard Oriole nests are often parasitized by Brown-headed Cowbirds, and only half as many Orchard Oriole young are fledged from parasitized nests as from unparasitized nests. This is thought to be one reason for substantial population declines in some parts of the U.S.
