Williamson's Sapsucker, Sphyrapicus thyroideus


Williamson's Sapsucker
Williamson's Sapsucker has the most striking difference in appearance between males
and females of any North American woodpecker, as shown above and below. Both
photos were taken at an active nest near to eye level; previously, I'd always found
birds of this species nesting high above the ground.

A male on his way to the nest to feed young birds. How do woodpeckers carry so
many insects to carry to the nest? I'd think that as they foraged, they would have to
open up to capture new ones, and the others would fall out.
