Subject: [obol] Black-eared Bushtit addenda
The other report on Obol today refers to a sighting some years ago in rural Harney County. Neither a current record nor at refuge HQs, which is perhaps 70km north of Page Springs. But the bird mentioned by Harry today was at the same location as the report and photo by someone else yesterday, so quite likely the same individual. The Sibley App, 2nd edition, states that black-eared individuals have been recorded in Colorado and California, typically males and always juveniles.Pyle( 1997) page 349 "Gray-crowned(P.m.plumbeus)Group. Some juv males with black in the auricular." Bear in mind that females acquire the pale eye many months after hatching, so it is reliable for sexing birds only after first prebasic molt. Color of throat and flank feathers is useful for sexing Bushtits, presumably in all ages, and especially the brown-crowned(western Oregon) and black-eared subspecies.Sent from my Verizon, Samsung Galaxy smartphone
