The Snow bunting is a large finch that breeds throughout the high arctic tundra. In winter, many move south, sometimes forming large flocks in open grasslands, steppes, and dunes.
When feeding in agricultural fields, these flocks may be hidden among the stubble, but when alarmed they often arise as a group and whirl about in a white cloud before returning to their spot or a nearby one.
Oregon is at the southern edge of their winter range, and their wanderings about the state are erratic. In basic plumage, they are buffy and cream-colored with black and white wings.
