The Dark-eyed Junco is a medium sized, common sparrow of North America. Its sub-species (whose numbers are disputed) are distinguished by variations in plumage, although they all have similar habits.
This page will detail the Oregon subspecies, which can be identified by its distinct black head, rufous flanks, chestnut back, and white to beige belly and breast. It also has white outer tail feathers that flash when in flight, a tan beak, and pink legs and feet. The Dark-eyed Junco is weakly sexually dimorphic. Males are slightly darker than females (Dunn 2002).
