Beobachtungsdetails
Found on Oct 9 by Hugh Cotter. This is an immature female representing the first county record for San Francisco. Identified as female by lack of black mottling on chest, crown feathers buffy with dark shaft streaks, and median coverts light buff lacking rusty tips. Note the long primary projection with four primaries visible past the folded tertials. This helps distinguish McCown's from the similar Chestnut-collared Longspur (Calcarius ornatus).
