Coues' Flycatcher
Contopus pertinax
Dec.26 Parker Dam, San Bernardino Co., Calif.: 1 in GOVT residences at Parker Dam where found a few days ago. Size and shape of Olive-sided Flycatcher but underparts a nearly uniform brownish - throat paler and center of belly paler (buffy-brown - says Phoebe-like) but rest of underpart uniform brown without the vested appearance of Olive-sided.
Lower mandible bright orange-yellow; two obscure whitish wingbars; forehead extremely steep and head very pointed.
Call notes - "chip" or "chip-chip" - sharp, somewhat like Red Crossbill. Sang 3-4 times - "Jose Maria" whistle, or slightly abbreviated version. Watched for 10 minutes from as close as 30 ft. as it sallied from short trees and the handle bars of a tricycle 3-10 ft. above the ground - outstanding views.
