Sep. 28 373 Gravatt Dr, Oakland, Alameda Co, Calif : 1 imm at feeder
Oct. 10 373 Gravatt : 1 imm. at feeder , noted intermittently and several times in company with a brown winter adult up to Dec-14.
Nov: 17 373 Gravatt ; although I thought I had been seeing more than one individual at my feeder, today it was proved - both birds present at the same time.
