The Jewels of the Canopy: Treetop Treasure

Look: Golden-yellow face, dark cheek patch, olive-green back, and yellow breast with black streaks.
Bay Area Schedule: Winter resident arriving from northern forests; most migrate back north in early spring to breed in summer.
Fascinating Facts
High-Canopy Hunters: Townsend's Warblers spend their days high in trees searching for caterpillars, beetles, and other insects.
A Sweet Winter Treat: Although mainly insect-eaters, occasionally they may drink nectar from hummingbird feeders, especially when natural insect food is scarce.
Winter Team Players: They often join mixed-species flocks with chickadees and kinglets, helping each other find food and watch for predators.
