Williamson's Sapsucker

Sphyrapicus thyroideus

Williamson's Sapsucker
copyright Brian Small
Length: 9 in. (23 cm)
Large sap wells are excavated in shallow but neat rows on the bark of a tree, and they are usually the first evidence of this sapsucker's presence. The oozing sap as well as the insects attracted to it serve as a major source of food at some times of the year. The Williamson's Sapsucker is found in mountainous conifer forests and also feeds on ants and fruit in different seasons. The nest cavity is excavated in a conifer trunk from low down to almost the canopy. In the winter the females go to more open areas and are seldom found together with males. The four-digit banding code is WISA.
