Undaunted by GLGU struggles, I ventured south to Santa Clara County for a continuing Barrow's Goldeneye (BAGO) on November 28th. Fortunately that bird cooperated, and I had prolonged looks at the bird as it foraged on the far side of Shoreline Lake (too far for digiscope photos). That bird added Santa Clara bike bird #214, I birded my way through Byxbee Park and the Palo Alto Baylands on my return. Scanning from San Francisquito Creek, the border between Santa Clara and San Mateo counties, I watched 3 Bonaparte's Gulls (BOGU) fly from the former to the later. I'd seen BOGU on San Mateo pelagics, but it was good to redeem that 'dirty bird' for a long overdue San Mateo bike bird (#284). The Bonaparte's were even farther away than the Barrow's, so no photo of that bird either.

Post #187 - Recent Bay Area Biking - Punctural Sandpiper and Pacific Golden-Puncture
Despite the fact we didn't have a single Pectoral Sandpiper (PESA) in San Mateo County this fall (according to eBird anyway), the species made strong showings in neighboring San Francisco and Santa Clara Counties. Don Edwards NWR in Alviso was historically productive; 60-plus birds were recorded through the first week in October, and at least 30 remained on October 13 when they were joined by at least one Pacific Golden-Plover (PGPL). PESA numbers eroded through the next week, but a handful remained through the 21st, as did the PGPL. I'd watched daily reports of both species roll in, and I was finally able to ride for them on the morning of October 22nd.
The first hour of my pursuit ride unfolded without incident, but I skidded off Middleton Road in Atherton when a metal rod punctured my rear tire. No big deal; I swapped in a new tube an continued after a 13 minute delay (yeah, I timed it).

Post #186 - Rusty Blackbird Spotlight
When an out-of-range Rusty Blackbird (RUBL) was found at the southern end of my home San Mateo County (California) on October 27th, I faced mutually-exclusive choices for the morning of the 28th.
Option #1 was to pursue the bird by bike. The wandering individual was the first RUBL to stray into biking range since I moved to San Mateo in May of 2017, and the species would be a fantastic addition to my cherished Bay Area Bike List (324 species to date). With over 3,500 feet of climbing spread across 74 round-trip miles, the ride would be an exhausting undertaking and consume an entire day.
Option #2 was to pursue the bird by car so I could photograph it. RUBL would be a new species for my photo collection, and the folks who observed the bird on the 27th noted that it was very approachable. My 600mm lens is too valuable and heavy to carry on the bike; even if I was willing and able to ride with it, then I'd to need to leave at 3am to reach the the bird by sunrise. So yeah, I'd drive if I opted for photography.
Decision, decisions.....bike or photograph?

Post #185 - San Francisco Bike Birding
Fall migration is slowing down, but there this year's iteration brought loads of interesting birds to the Bay Area. Several of those appeared in San Francisco between October 8 and 12, and I'll use this post to highlight three trips I made to the city in that window. Fall is usually great weather around here, so its a fun time to be on the bike!
San Francisco, October 8
This afternoon sprint targeted three species: Long-billed Dowitcher (LBDO) and Pectoral Sandpiper (PESA) at Yosemite Slough on the bayshore and Philadelphia Vireo (PHVI) at Lake Merced. The two shorebirds aren't rare in the Bay Area, the dowitcher in particular, but there's next to no habitat for them in the city; hence they're good San Francisco County birds. Contrarily, the vireo is an excellent find anywhere in California, examples often found in urban parks which receive lots of coverage.
The vireo was the most exciting bird of the three, but I prioritized the two shorebirds since they'd occupied the same small pond for 4-5 consecutive days and would be easy to find, assuming they were present. The continuing group of 7 LBDOs was exactly as advertised when I reached Yosemite Slough (SF Bike Bird #225), but additional scanning over the next 30 minutes failed to reveal the PESA. Conceding that bird, I crossed the city for the PHVI but was unable to find it with remaining daylight. Originally found in the morning, it was last seen when I departed San Mateo at 2:30pm. Had I pursued it first, I would have spent remaining the remainder of the afternoon searching for it, failed to reach Yosemite Slough, and missed the LBDO as well. So, one outta three.....
San Francisco, October 8
Rode hella fast, so loop took 2.5 hours
San Francisco, October 12
With Tropical Kingbird (TRKI) and Red Phalarope (REPH) reported from Lake Merced on the previous afternoon, I shuffled my schedule and made a morning run for that pair. I struck out on both, but ended up with three consolation prizes. The first was an overhead flock of Cackling Geese (CACG) for SF Bike Bird #228. The next was a completely unexpected Green-tailed Towhee (GTTO) which I found while looking for the TRKI. I was able to snap a quick digi-binoc of the GTTO (SF Bike Bird #229) before it vanished. While a number of us worked to relocated the towhee, Aaron Maizlish pointed out a Blackpoll Warbler (BLWA) for SF Bike Bird #230. I took off before the towhee was refound, but it did surface for many others that afternoon and through the following day. Frustratingly, the REPH was also seen later in the day, so I should have looked harder for that bird while I was there. Given that the towhee was a better bird than either TRKI or REPH, I chalked the morning up as a big win. I'd seen REPH in SF waters on pelagic trips, and I'm sure I'll get one by bike in SF eventually.

Post #184 - Solano County Photography
With international travel shut down and domestic travel dissuaded in the COVID age, I've explored more of the Bay Area in 2020 than in previous years. Much of my wandering has been on my bike, but I have ventured farther afield in the car. I'd not, for example, birded in Solano County prior to March, and I've had fun exploring that southern end of that area in the intervening months. Lagoon Valley outside Vacaville has proven particularly productive (eBird hotspot), and I'm going to use this post to share a few photos I recently captured at the park. It's worth noting Lagoon Valley barely escaped the gigantic LNU Fire which roared through nearby Vacaville in August; the fire approached the park on two sides but ultimately spared it.

Post #183 - Fall Bay Area Bike-birding Update
I wrote in June that I'd established a torrid bike-birding pace through the first half of this year, and I've continued that momentum through to fall. To date, I've amassed 2,251 miles, the equivalent to driving from San Francisco to Indianapolis. I biked 2,086 miles in 2019 and 2,001 in 2018, so this year represents a significant increase. Stoked cuz though miles allow me more pizza, donuts, and ice cream.
Incidentally, I had Sooty Shearwater on my regular (i.e. petroleum powered) SF list from Alvaro's Adventures pelagic trips, so I was trying redeem that "dirty" bird. I failed on JUne 30th but succeeded a few weeks later, on August 13. I finally got the pelican on September 24, after 3 misses.
