Sapsuckers, as thier name implies, are birds that feed on oozing sap and the insects found in trees. They are enabled to feed in such a manner by their tongues, which are coated with minute hairs to extract sap.
Williamson's Sapsucker was discovered around 1852 in the western United States. It was named after one of the explorers who initially spotted it. The Williamson's Sapsucker is normally 8 to 9 inches in length. Males are predominantly black with a red chin, yellow belly and white markings on the face and wings. Females have a brown head with a white rump and a yellow belly. They dwell almost exclusively in the pine forests of the American West.
