Yesterday, 15 November 2021, Nicole Desnoyers and I were working outside of our office on a foggy day on San Clemente Island. A group of unfamiliar birds flew over calling, dropping down to a homemade bird bath. The birds, which we were not completely, just mostly(!), shocked to see were SWINHOE'S WHITE-EYES (presumably from the mainland, whereI don't know that physical/genetic evidence has yet to confirm the species involved here in Southern California). This introduced species has certainly expanded its range in recent years in Southern California, having just been recorded in Ventura County in October, and now known as far south as the Tijuana River Valley in San Diego. In December 2018, the Scheels found the first white-eyes for Catalina Island, and now Clemente has joined in the fun. Given this species ability to move from island to island in its native range (much like Scaly-breasted Munia, which has now occurred twice on San Clemente Island), it was just a matter of time before they made it to San Clemente, I suppose. Swinhoe's White-eye is on the CBRC watch list , and is certainly doing its best to lobby for addition to the state list.

Other firsts for San Clemente Island this fall include a RED-FOOTED BOOBY (overdue, given this species status in California of late) on 1 November: https://ebird.org/checklist/S97085514
and a PINE WARBLER on 3 November (a species very much on the move in California this year): https://ebird.org/checklist/S97092986
