Cogswell 1949 Empidonax hammondii Vireo solitarius -2- Aug. 22 7:30 mi. W. Schoolhouse Peak, 2300 ft., Humboldt 10:30 a.m. Ca. Calif. I found two Empidonax flycatchers foraging from the larger branches or bare twigs under the canopy of the barry oaks here on a steep SW. facing slope quite close to the edge of a large grassy "prairie". One was collected as it flew to a perch in a low oak at the margin of the woodland. It seems to be this species (= #50). Neither bird was heard to utter a note; they are presumably mis- giants, or at least not in their nesting area. - Nov. 7- This specimen turns out to be a Vireo!! - Vireo solitarius. The other individual seen behaved so much like a flycatcher that I still believe it was but this bird was shot so soon after I saw it alight in the twigs that I did not have time to check on its behavior — but merely assumed, unwisely, that they were the same.
