Breeds mostly in moist, dense forests near sea level, especially in forests of Douglas-fir, hemlock, and western redcedar. Also nests in cooler, wetter forests of fir and other trees at higher elevations. In w
inter, found in pine-oak forests of mountains in Mexico, also in oaks and conifers along California coast.
Nest: Typical site is on horizontal branch, well out from trunk and 20-40′ above the ground. Nest is a compact, deep, open cup of fibrous weed stalks, pine needles, twigs, lichen, moss, cobwebs, lined
with soft material including bark, feathers, and animal hair. Female alone builds nest.
5, sometimes 3. Creamy white, with fine brown flecks in wreath at larger end. Incubation is probably by both parents, and probably lasts about 12 days. This species apparently is almost never parasitized by cowbirds.
Young: Fed by female and possibly by male as well. Young leave the nest 8-10 days after hatching.
Behavior: Forages mainly in the canopy of tall trees, sometimes up to 200′ above the ground. Males often forage higher than females. Takes insects from twigs while perching and while hovering, and flies out to
catch insects in midair. Will hang from twigs like a chickadee. During migration and in winter, often forages in flocks with other birds.
b Migration: Migrates most commonly north along the Pacific Coast in spring and south through the mountains in fall. Southward migration begins early, with many on the move in August or even late July.
