Picid in Focus: Williamson's Sapsucker Sphyrapicus thyroideus

Most Williamson's Sapsuckers are migratory, breeding in the north of the USA and Canada and wintering further south as far as Mexico. It is also one of the most sexually dimorphic woodpeckers in terms of plumage, with the sexes visually very different. Males are well marked and coloured and females much duller. Photo of this male taken by Steve Shunk, Oregon, USA.
