Fort Mason and Crissy Field Local Interest

David Assmann
 

Spent the first half of the morning at Fort Mason, where the ORCHARD ORIOLE continued in the garden. An ORANGE-CROWNED WARBLER near the west side of the garden was very aggressive, chasing after AMERICAN ROBINS - a behavior I have not observed before. On my way to Crissy Field I stopped at the Yacht Harbor, where four SURFBIRDS foraged on the rocks. At the northwest corner of Crissy Lagoon, two SAVANNAH SPARROWS were in the willows, and on the field I observed several WESTERN MEADOWLARKS and spotted an AMERICAN PIPIT.

Ferry Park (Sue Bierman) - Wilson's Warbler 3-1-19

Jack Hayden
 

The wintering Wilson's Warbler continues at Ferry Park (as of March 1). Among birds currently reported on eBird, this is the most northerly Wilson's along the west coast of the US. Interesting to note there is another Wilson's wintering in British Columbia.

Also present is the continuing White-throated Sparrow and three other warbler species.

Spotted Towhee in Lafayette Park

A spotted towhee was actively foraging with a group of robins and starlings on the slope north of the concrete walkway opposite the tennis courts.

Long-tailed duck still around

Bob Hall
 

Took a long walk yesterday to see the white duck of the crashing surf. Didn't expect to get lucky, but there was the long-tailed duck about 50 feet off the beach. Easy views, no scope necessary. Another birder pointed out some female black scooters. Nice, close looks at Pacific loons, too.

On the way over I heard a Wilson's warbler singing in the Lobos Dunes willows. I also heard two or three Bewicks wrens. They seem to be a fixture there now. Today, in my backyard, I saw my FOS orange crown warbler.

Regarding the Baker Beach sighting

Bob Hall
 

I was told that I likely saw a red-throated loon and not a Pacific loon. My birding skills have surely eroded due to neglect but I still arrogantly walk around without a bird guide, for some reason!

cont. Blackburnian Warbler

 

Yesterday I had business at the SF Zoo so I stopped at Lake Merced Park to look for the Blackburnian Warbler found on the CBC (12/27/18) by Peter Pyle, and last observed in early February.

After spending some time sorting through Yellow-rumped Warblers in the willows and myoporums on the south side of the entrance road from Skyline Blvd. the BLACKBURNIAN Warbler was relocated alive and still wintering. As in previous visits the soft call note preceded laying eyes on the bird as it feeds very quietly and almost in the creeping manner of Black&White Warbler than the frequently sallying Yellow-rumps. A wad of feathers and tree gum has formed over the bird's bill as is typical of exotic nectar tree clients by this late into the winter but this time it was feeding in the budding Arroyo Willows.

If anyone has anyone significant sightings from December - Feb that didn't make it on to the list let me know offline as I am beginning to compile the winter report.

Thank you,

Eastern Phoebe continues, 3/7

The Eastern Phoebe continued this morning, just above the trail from the north end of Crestline and below the Twin Peaks restrooms.  Also present was a House Wren in full song.

Long-tailed Duck continues at Baker Beach

 

Late afternoon today I walked along Baker Beach and sighted the Long-tailed Duck mixed in with a small group of Surf (18) and Black (3) Scoters. From there I walked along the Battery to Bluffs trail and sighted a large raft (200+) of Surf Scoters east of Baker Beach.

Thanks Josiah.

Fort Mason Local Interest

David Assmann
 

Spent about 45 minutes this morning at Fort Mason, before the rain really started to come down. The ORCHARD ORIOLE and LINCOLN'S SPARROW continue in the garden. Checked out the Battery, where the tree removal has finished. Virtually all the trees from the lower hillside above Black Point are now gone.  There are two very small trees remaining, leaving an expansive view of the Bay. It will be interesting to see if the tree removal affects migration sightings. The mounds of wood chips left behind are attracting many sparrows (I saw a group of eight FOX SPARROWS in one very small area), as well as YELLOW-RUMPED WARBLERS. AMERICAN ROBINS were everywhere this morning - singing in the rain.  And speaking of singing, the WESTERN MEADOWLARKS at Heron's Head Park are now singing - one of my favorite aural experiences.  SAVANNAH SPARROWS are also singing at Heron's Head.

Eastern Phoebe March 10

Dave Weber
 

Just spent an hour at frigid Twin Peaks watching the tour buses arrive and the workers cleaning up after the city's finest. At 9 am, and about to leave, suddenly the Eastern Phoebe was right  in front of me. Just downhill of the restroom is an orange and white post, no doubt hurled there, in the coyote bush. Phoebe was closer than that! Then it was gone.

11:43am fly catching between the apartments below the restroom building and bottom of the draw, below Twin Peaks restroom. Landed on one of the roofs after catching a bug, then flew northeast in the narrow gap between buildings and hillside, out of view.

Good birding!

Western Kingbird at Fort Mason

David Assmann
 

Early - my earliest previous sighting was on March 16th. 

Re: Western Kingbird at Fort Mason

Richard Bradus
 

Also seems early to me - on a walkabout around 1pm I noted three Violet-green Swallows (FOS) around the NE corner of Alta Plaza Park. Looked like a possible pair and a rival, and they were repeatedly exploring the roof cornices of the houses and apartment buildings along Steiner St., apparently searching for possible nest sites rather than gleaning for insects.

Is it the switch to Daylight Savings Time?, or maybe the return of the sun has prompted the early migration.

Presidio Arrivals and Marin Audubon field trip report

Josiah Clark
 

Yesterday there were 4 returning rough- winged and 1 barn swallow over mountain lake. Being mid March, it’s definitely the expected time for early migrants.
On Sunday I lead up a Marin Audubon field trip starting at baker beach. We had the Red-necked Grebe, Black Scoters and Long-tailed Duck among 176 Surf Scoters. I learned from our resident academic Sam Saffron about scoter trends, that they have experienced a 10 fold decrease in the last 20 years on the pacific coast.
Other noteworthy birds were high counts of 5 Wrentits on the coastal bluffs (4 in view at once) and 8 Bewick’s Wrens, present at nearly every site we visited. We watched a pair building a nest among the many downed pines the historic “forest”. Populations of both these species have nearly blinked out in the passed. A spotted towhee continues at lobos creek.
We also focused some attention on rare and specialized plants including the rare and endemic San Francisco Wall Flower, which are in bloom right now.

BUSHTITS have been going in and out of a nest in one of the few remaining trees on the lower Battery.  An ANNA'S HUMMINGBIRD recent fledgling was being fed by a parent above Aquatic Park. And AMERICAN CROWS are actively nest building. The WANDERING TATTLER was in Aquatic Park.  Briefly heard, but did not see, the Orchard Oriole. Got good looks at a LINCOLN'S SPARROW preening in the garden, and an ORANGE-CROWNED WARBLER was working the west fence. Six BROWN-HEADED COWBIRDS were clearly new arrivals.

Crissy Grebe grand slam and “Bike big hour”

Josiah Clark
 

With the longer days and clear weather I took an hour off the computer to do some spring reconnaissance around the presidio.
Six pieces of grebes were present around Crissy Field, where red-necked, Horned Western and Clark’s were together by the torpedo wharf.
One snowy plover was in the water bird protection area, with a beached/ship-wrecked pied-billed Grebe onshore that needed the protection.
56 species for the hour. No swallows today and very few land birds, but it was late in the day. As others may have noticed I have observed an absence of turnstones and Surf birds in recent weeks at Baker Beach and the cliffhouse, probably due to the big waves and high seas.
I am making a point to take in the rapid transition in bird communities over then next month and a half.
Happy spring, Josiah Clark

Pigeon guillemot and scoter movement baker beach

Josiah Clark
 

I counted 358 Surf Scoters Baker Beach. Almost twice as many as I had on the weekend. There were also for red-necked grebes and four female black scoters, more than I’ve ever seen of either species in the presidio at once.
This is unprecedented in my memory for Baker Beach to have so many Scoters for so long. I have not seen much active feeding but I imagine they are going after sand crabs, one of the few food sources out there in the surf. Perhaps there has been some kind of underwater sand movement that has yielded a new food source.
I looked hard but could not find a long-tailed duck. The pigeon guillemot was looking handsome right off the middle of the beach not too far out. First of season for me.
