WESTERN FLYCATCHER.
464. Empidonax difficilis. 6 inches.
Very much like the last, but having more of the yellow cast on the under parts; it may be found breeding from Alaska to southern California. Its favorite nesting place is along some stream, bordered with willows or alders, and the nest is placed on the lower branches near the ground; it is nicely made of fibers and plant down; three or four white eggs, spotted with brown (.80 × .55).
