Surfbird - The Surfbird is a small stocky wader in the family Scolopacidae. It is usually classified in a genus of its own, as Aphriza virgata, but more recent data suggests it is very close genetically to the Red and Great Knots and should be included in Calidris . Indeed, the Great Knot looks very much like a larger, more long-billed, and somewhat darker surfbird.
