Yesterday I logged some field time on Ocean Beach, seawatching from Fort Funston, and then on a dropping/low tide checked for shorebirds etc. at Yosemite Slough and Heron's Head.

Sightings of note to me:

White-winged Scoter - 4m 3f off Funston

Snowy Plover - 0(!) at traditional winter roost sites on Ocean Beach between Judah and Noriega following the warm weekend and corresponding increase in people activity on the beach,where do they go ?

Semipalmated Plover - 1 at Yosemite Slough was a very low count, sometimes 40-50 are noted at this site

Dunlin - 460, a good count for SF, on Yosemite Slough Delta at uncovering

Western Sandpiper- 20+ mixed in with Dunlin, good count for SF outside of spring/fall migration window

Selasphorus Hummingbird - obvious northbound migrant off Fort Funston flew through my field of vision while I was scoping the scoter rafts

Tree Swallows/Swallow sp. - 10-12 northbound off Funston

Savannah Sparrow - countersinging birds at Heron's Head where they first re-established as a nesting bird in SF c.2010-11 after decades of absence, as well as at least two birds countersinging at Yosemite Slough where they were suspected of breeding attempt last summer

SONG SPARROW - brief but definitive looks at a song sparrow at Heron's Head Park that appeared to be of the darker NW Pacific group (Morphna/Merrilli). This is the first time I've seen Song Sparrow at Heron's Head in many years of visiting this site. Their status here and other Bayside spots in the county (Pier 94/Candlestick/YosemiteSlough) is confused by a vast number of records in eBird many of which I suspect may be data entry errors or mistaken IDs. If you think you have a Song Sparrow at these sites take care to study it. Just as Ridgway's Rail and Savannah Sparrow came back to nest at Heron's Head I think there is the chance that Alameda Song Sparrow, a salt marsh specialist long ago extirpated from San Francisco could potentially attempt to colonize here as well.

Also, just thought I'd put this out there having now read several reports of heard only Tanagers in West Golden Gate Park the past couple weeks. Last Monday (1/29) while birding around North Lake with Peter Metropulos, I heard several calls that I initially took to be the "pit-trrrick" of Western Tanager. The bird resumed calling again after a few minutes and then the short burst calls morphed into the full length rattle of NUTTALL's Woodpecker which has become established as a resident species in this part of the park only in the past 4-5 years and confirmed nesting only in 2014-15(?)
