Dusky Flycatcher
Empidonax oberholseri
June 20 East Mojave Desert, San Bernardino Co. Calif.: pair in
white fir patch - Nest with 4 eggs in a white fir
sapling about 4' off the ground. First breeding record for
the NY mountains. Two other birds were heard singing
in pinyon-live oak away from white firs @700-7000'.
June 21 Kingston Range, San Bernardino Co. Calif.: 4 singing birds
in canyons A and B @600-@800 ft. in pure pinyon.
These birds were > 1 mile from the white firs - this
species certainly does not need white firs
