The stream of interesting migrants continues! I've been out on the bike a fair amount lately, and I'll use this entry to highlight a few birds I've intersected since my last post. Let's get rolling....
Canada Warbler (CAWA) is an eastern species which occurs in California as a rare migrant, usually in fall (range map below). Beyond a would-be addition to my Bay Area Bike List, CAWA would be a state bird for me because I'd not intersected it anywhere in California -- by bike or by car -- since moving from Boston in April of 2015. That as a backdrop, I sprung into action when Aaron Maizlish reported one at the Colma Creek mouth on the San Mateo bayshore on September 14. The report came in 2.5 hours after the original sighting, and I wasn't optimistic about relocating the bird given the huge wind which had materialized in the interim. I saddled-up regardless and -- to my surprise -- relocated the bird after a ten minute search. Other birders arrived a bit later, and the subject showed well through the afternoon and the next day. It was the first CAWA reported in the county since 2014, so it was well-received by all.
What the hell is that? Could it be a Ruff ? No way - they're hella rare around here.
I jumped off the bike, fished out my the scope, and threw it onto the tripod, my subsequent view to the bird confirming my Ruff suspicion! I snapped a few digiscope pics, but the bird vanished while I was posting it to the Telegram group and list server. Fortunately, I relocated it from another vantage half an hour later, and at least one other person arrived in time to see it. Ruff is a great find for San Mateo -- there are only a handful of county records -- but it wasn't a Bay Area Bike Bird since I observed one in Santa Clara at Don Edwards on November 3, 2018.
