Join Golden Gate Audubon Society’s new Christmas-in-May Bird Counts (CiMBC) on Saturday, May 8th. Find as many bird species as possible in your chosen area… while contributing to community science and generating funds to protect Bay Area birds. This count is on Ebird's Global Big Day, and will use the same area boundaries as the Christmas Bird Count in San Francisco.  See details at https://goldengateaudubon.org/birdathon-main-page/christmas-in-may-count/

Sequoia Audubon April 8 Monthly Meeting

Sequoia Audubon Society
 

This Thursday, April 8, our monthly meeting topic is Gender Equity and Public Access on the California Coast. Sabrina Brennan will speak about her efforts to improve gender equity, and in the process improve access to Mavericks and Pillar Point Harbor.
As a former countywide elected San Mateo County Harbor Commissioner, she successfully advocated to develop a living shoreline at the West Trail located near Pillar Point Marsh; the project will be complete in early 2022. She's advocated for the construction of a new visitor facility near Surfer's Beach that would include numerous improvements. As well as, for women to be included in the Mavericks big wave surf competition and persuaded the California Coastal Commission to require that women athletes be included! Register here: http://www.sequoia-audubon.org/meetings.html

"Socializing" at 6:30, meeting starts at 7:00pm. Hope you'll join us!


Great Blue's Excellent Breakfast Adventure

Brian Fitch
 

We were treated to the sight of this Great Blue Heron raiding our neighbor's outdoor fish pond yesterday morning around 8 AM.  We had no idea that they were keeping fish up on this third floor deck off of 14th Street, but the gorgeous yet unfortunate fish caught the heron's eye as it flew from bayside toward the west.

False alarm: checking the photos, it looks like a gray-headed OCWA.

Kingbird

Donna Hayes
 

At around 12:30 Friday afternoon, I saw a Western kingbird on Bernal Hill. It was perched on a bare tree north of the trail on the way to the summit.

I will check again tomorrow.

Otherwise a very quiet day.

Re: Local Interest Fort Mason - Baltimore Oriole, Western Kingbird, Elegant Tern

Missed almost all of these but got the Townsend’s to pose.

Three Oriole species were visible at Fort Mason this morning, including the overwintering BALTIMORE ORIOLE, a BULLOCK'S ORIOLE and a HOODED ORIOLE.  There were six warbler species in the garden.  I missed the Black-Throated Gray Warbler seen by others, but I saw YELLOW-RUMPED WARBLERS (numbers of this species are going down), TOWNSEND'S WARBLER, ORANGE-CROWNED WARBLER, WILSON'S WARBLER and NASHVILLE WARBLER. 2 PIGEON GUILLEMOTS floated offshore. 1 ELEGANT TERN and 2 CASPIAN TERNS flew over. Got good looks at 2 WESTERN KINGBIRDS, and a quick look at another flock of 8 that I believe were also WESTERN KINGBIRDS. A GREAT TAILED GRACKLE flew over. A quick visit to Crissy Lagoon yielded a WILSON'S SNIPE, a CLIFF SWALLOW, a WILLET turning into alternate plumage, and six LEAST SANDPIPERS almost entirely in alternate plumage.

B Godfrey Again

Numbers and variety were lower today, as the first big spring pulse seemed to be waning.  Species we didn't see yesterday but did today included Cliff Swallows and Black-throated Gray Warblers.  Kingbirds were much more numerous with over 70 at BG and Peter had over 200 on the east side of the toll plaza. 

Things went dead after 10, and the crew dispersed after 11, but not before we saw flocks of 5 and then 6 Elegant Terns come in off the ocean and into the Gate.  It seems that they arrive earlier every year.

6 active gbh nests at Stow Lake correction and heatwave migration

Josiah Clark
 

I was thankful to hear from Stow Lake rookery extraordinaire Nancy DeStefanis, who wanted to assure everyone there are in fact 6 active nests this year. Great news! Apparently they shuffled around after their nesting tree split in half. 
 On the subject of rocky shorebird declines, I will note the same pattern continues around the expansive rocky areas of lands end i access by kayak and others observers in Pacifica are confirming similar findings. 
   In arrival news I also heard about several more Wilson’s warblers and hooded orioles arriving in the city over the last couple of days. 
    Sounds like it will be a day of record-smashing heat and offshore flow today with temps 20 degrees above the seasonal average.  There will likely be some northbound hawk and songbird movement.
 Keep an eye to the sky especially around hilltops, but wear your sunglasses and sunscreen.

Re: Field trip summary from Sunday and ecology report

Joel,

I don't think dogs have much to do with it. When I began birding here in the 70s mussel and barnacle covered rocks were exposed all the way down to the seawall at Ocean Beach at low tide. All the rocks along the shore are covered with sand now. I think that this is well worth remembering when people talk of sea level rise at the southern end of the beach. I don't doubt that sea level rise is happening but beaches are dynamic and sand moves over time.

I suspect that the lack of rocky shorebirds at the Cliff House area may have something to do with the widening beach there.  It seems like there is much more of the day when people and dogs can access the beach below the rocky cliffs.
