California Gull californicus 0945-575xx 2nd cycle (2CY), September 08 2009, Southeast Farallon Island, San Francisco Co., CA. Picture: Jim Tietz.Please visit Farallonia's site for more images! "During the early part of the fall, large numbers of California Gulls migrate away from their inland breeding locations to overwinter along the Pacific Coastline or out on the open ocean. Hundreds of these gulls roost on the island each night. We have suspected that a large number of these birds originate from the relatively close Mono Lake or the burgeoning colony in South San Francisco Bay. On 8 Sept, we photographed a 2nd-year California Gull roosting on the Marine Terrace that was wearing a band. Three of the digits on the band (575) were legible. HY2008. Bird at end of the complete moult, from 1st > 2nd cycle.
