Habitat
The habitat of Western Flycatchers includes both deciduous and mixed deciduous-coniferous forests. These birds are generally found in the sub-canopy of heavy, wet forest. Streamsides and shady areas with shrubby understory are often used. Along the outer coast, they are the only Empidonax flycatchers commonly found in the dense, wet rain forest of this region.
Behavior
The Western Flycatcher generally watches from a perch in the lower or middle canopy, and flies out to catch prey in the air. It also hovers in front of foliage or twigs and gleans prey from their surfaces. This species can be very hard to see, but can be found readily once its call is known--a distinct, upslurred suweet, or a high, thin tseep.
Diet
Western Flycatchers eat mostly flying insects as well as some crawling insects.
Nesting
Western Flycatchers usually select natural sites such as trees for nesting. Very occasionally they nest under man-made bridges or eaves. Nests usually have some sort of shelter from above. Natural nesting sites include tree stumps and upturned tree roots, which are typically closer to the ground than nests on man-made objects. The female builds the nest of moss, grass, rootlets, bark, and lichen, and lines it with hair and feathers. She usually incubates three to four eggs for 14 to 15 days. Both parents feed the young, which leave the nest at about 15 days. The young stay near the nest for a few days after fledging.
Migration Status
These medium-distance migrants arrive in Washington in late April or early May. Most birds leave in late July and early August; however, some stay into mid-September. They head to the lowlands of western and southern Mexico for the winter.
Conservation Status
The Western Flycatcher is listed on the Audubon Washington watch list. The Breeding Bird Survey has recorded a significant decline in Washington from 1980-2000. While man-made structures may add potential nesting sites, logging and clearing underbrush degrades the habitat.
