Date   
Fort Mason Last Two Days - Blackburnian, Chat, etc.

David Assmann
 

The highlight of this morning's GGAS field trip at Fort Mason was a BLACKBURNIAN WARBLER found a little after 9, and seen again around 10:30. Other warblers included an ORANGE-CROWNED WARBLER, at least 7 TOWNSEND'S WARBLERS, and 16+ YELLOW WARBLERS. There were at least 9 WESTERN TANAGERS, 5 WARBLING VIREOS, a BULLOCK'S ORIOLE, a SWAINSON'S THRUSH, 2 GOLDEN-CROWNED SPARROWS, a FOX SPARROW, a BEWICK'S WREN, 2 HOUSE WRENS, 2 or more RED-BREASTED NUTHATCHES, a SHARP-SHINNED HAWK, and at least 2 PACIFIC-SLOPE FLYCATCHERS.

Yesterday the highlight was a YELLOW-BREASTED CHAT in a Cabbage Palm on the hillside above Aquatic Park.  Also seen were a BLACK-HEADED GROSBEAK, 7 WESTERN TANAGERS, a WILSON'S WARBLER, 2 TOWNSEND'S WARBLERS, 26+ YELLOW WARBLERS, a COMMON YELLOWTHROAT, 2 GOLDEN-CROWNED SPARROWS, a WILLOW FLYCATCHER, 2 PACIFIC-SLOPE FLYCATCHERS, 3 WARBLING VIREOS, and 3 CEDAR WAXWINGS.

Poor quality photos of the Chat and Blackburnian attached.

Black-and-White Warbler et al, Western SF, 9/15/19

Paul Saraceni
 

This morning Hugh Cotter and I checked a number of locations on the W side of the City.


Sea-watching from the S end of the Great Highway was highlighted by thousands of Sooty Shearwaters streaming N nearly the entire time, 20+ Parasitic Jaegers on the move and harassing Elegant Terns, small numbers of each of the 3 regular loon species, 1 juv. Common Murre and 2 juv. Pigeon Guillemots, and 9 Red-necked Phalaropes flying over the ocean.  Hugh also spotted a N. Pintail and a Green-winged Teal flying together S over the ocean.  The only large shorebirds we observed this morning were 2 Whimbrel (the regular Hudsonicus ssp.) on the beach.


We next walked a loop including the East Wash, the "plateau" west of the Legion of Honor, the West Battery beyond the VA Hospital, and then back to the East Wash.  Small numbers of some typical migrants were around. Red-breasted Nuthatches were seemingly everywhere -- at least 20+ observed during our walk. There were also 2 Willow and 2 "Western" Flycatchers, a House Wren, 4 W. Bluebirds, and a Great Horned Owl that we heard daytime-calling from somewhere E of the East Wash. 


Around 10:30, near the trail intersection closest to the West Battery, I briefly observed an imm. BLACK-AND-WHITE WARBLER which flew out of a cypress tree and dropped down into lower trees before it disappeared to the north. It was not with a flock, though there was a Willow Flycatcher nearby. We were unable to relocate the warbler.


Our final stop was Kobbe Upton / Ft. Scott, where sightings included a Say's Phoebe, 13 W. Bluebirds, and a Yellow-rumped Warbler in the field, as well as a Red-breasted Sapsucker in the trees above the tennis courts.

Thank you, Dominik!
And while there please do not forget to watch the sunset.
They are amazing in San Francisco.

Seeing beyond

Mila Zinkova
 

Hello everybody,

Yesterday I went to the Ocean Beach at Noriega. The Sooty Shearwater were everywhere. Plus there was another thing to see - a superior mirage of a ship https://www.youtube.com/watch?v=zQz2qpcoE24.
So the next time you'd go bird watching at the ocean don't forget to look at the horizon. 
Best,
Mila.

Agreed not pure Northern Pintail.
Could even be Pintail x Wigeon.

I’ve been seeing a lot of reports of the supposed eclipse male Northern Pintail at Lloyd Lake that is molting to adult plumage. In the photos I’ve been seeing, it doesn’t look to me like a pure pintail. Some things that seem wrong for pure pintail are the Rufous/brown feathers coming in on the breast. The breast of a pure pintail should be bright white, but this seems to indicate a Mallard X Pintail hybrid. Plus the head feathers molting in look blackish/iridescent which is completely wrong or Pintail. Again, points to Mallard X Pintail hybrid. Graeme Colmer’s photos show this very well, checklist linked here.

Pelagic report - Thursday

Alvaro Jaramillo
 

Hello all,

   We went out on a pelagic trip offshore from Half Moon Bay yesterday and encountered warm water offshore, and bird/whale rich waters about 10 miles out. As has been the pattern, a bloom of food is parked about 10 miles offshore with nice groups of Humpback whales and mixed shearwater flocks. Up to a dozen whales were seen in one spot feeding with hundreds of California Sea Lions, pretty incredible! Dozen more whales were in the distance. Bird abundance was much richer inshore and to the north of a warm water plume offshore. We found Ashy Storm-Petrel, a couple of small flocks of Buller’s Shearwaters, and all three jaegers including some nice adult Long-tails, and full spoon Pomarines. The constant high numbers of Arctic Terns continue, with the chance to get some nice photos of a close group foraging with Sabine’s Gulls. At one time about 10 Arctic Terns were being chased by a full breeding plumaged Parasitic Jaeger, dramatic and neat to watch. Most Arctics are adults out there, but we did see some juveniles as well. Two Tufted Puffins were a treat to see, now that they are dispersing from breeding grounds. Only a few Cassin’s Auklets were offshore as has been the case recently. Mammals were great – with densities of Pacific White-sided Dolphins coming close to the boat, beautiful bow riding Northern Right Whale Dolphins, and a nice little pod of Dall’s Porpoises offshore. The regulars were out there too, Black-footed Albatross, Sooty an Pink-footed shearwaters (many out there now), Common Murre, and Rhinoceros Auklet. A good group of a few thousand Sooty Shearwaters near shore allowed me to actually get a recoding of their voices, you don’t hear Sooty Shearwaters all that often. Here is the recording: https://ebird.org/view/checklist/S59708767

    Weather looks good for our trips tomorrow and Sunday. Low to moderate winds predicted, a tad lower on Sunday. Both trips are out of Half Moon Bay and we are hoping that this weekend we find our first Flesh-footed Shearwater of the season. This weekend’s trips expect to visit SF and San Mateo county waters. The change to the fall with arrival of crowned and fox sparrows makes me think that this could be when the Flesh-foot comes in! E-mail me or register online here for this weekend, or the Sept 21 trip out of Half Moon Bay, and 22nd trip out of Monterey:

About 50 AMERICAN CROWS mobbed a GREAT HORNED OWL this morning for at least an hour.  The owl didn't move, and the crows eventually stopped harassing it. Had my FOS FOX SPARROW (Battery) and SAY'S PHOEBE (Great Meadow).  1 BLACK-HEADED GROSBEAK, 18+ WESTERN TANAGERS, 1 WILSON'S WARBLER, 4 TOWNSEND'S WARBLERS, 14 YELLOW WARBLERS, 1 ORANGE-CROWNED WARBLER, 1 BULLOCK'S ORIOLE, 1 HOODED ORIOLE, 2 SAVANNAH SPARROWS, 1 HOUSE WREN, 1 RED-BREASTED NUTHATCH, 2 WILLOW FLYCATCHERS, 1 WANDERING TATTLER, and at least 5 PACIFIC-SLOPE (WESTERN) FLYCATCHERS.


Prairie Falcon at BG

Brian Fitch
 

It had been 22 years since I last saw a Prairie Falcon in SF, but the drought ended at 12:30 today when one coursed over Battery Godfrey, adding that one species that made an otherwise slow hawkwatch worthwhile.  Long, pointed falcon wings, tan body, dark axillaries; I don't know why it's been such a long gap between sightings for me, since they see multiples on Hawk Hill every fall, but it's obviously a tough bird in the city.

Other raptors included 1 northbound Turkey Vulture and 2 southbound, 3 Sharpies north, 2 Cooper's north, 1 Red-shouldered south, 6 Red-tailed north with 5 south, as well as the local Peregrine.

Other birds included a very high flying Great Egret, 2 Curlews, Glaucous-winged Gull, 5 Parasitic Jaegers over the bridge, with others pirating the terns and shearwaters, a few Band-tailed Pigeons, 2-3 Vaux's Swifts, Say's Phoebe, Warbling Vireo, Barn and Rough-winged Swallows, 3 Red-breasted Nuthatches, Blue-gray Gnatcatcher, 7 American Pipits coming in on the early side, Yellow, Townsend's, Black-throated Gray, MacGillivray's, and Wilson's Warblers, and at least 15 Western Tanagers, every one of them heading north.

The other highlight was already reported, although the number of Sooty Shearwaters went up to over 50,000 as I watched and scanned further out into the Gate.  The majority of them spent about 2 hours sitting on the water, with one group of roughly 10,000 drifting quite close to the battery and almost under the bridge, probably on the tide.  They then slowly dispersed until I didn't see any in the Gate when I left at 2:15.  There were still big dark swatches of them well out to sea though.

Fort Mason Local Interest - FOS Golden Crowned Sparrow

David Assmann
 

A short visit to Fort Mason this morning was fairly productive.  The number of WHITE-CROWNED SPARROWS has increased over the past two days, possibly due to returning birds. A FOS GOLDEN-CROWNED SPARROW was in the garden as well. Warblers today included at least 19 YELLOW WARBLERS, 3 ORANGE-CROWNED WARBLERS, 3 TOWNSEND'S WARBLERS, 1 WILSON'S WARBLER and a BLACK-THROATED GRAY WARBLER.  There were at least 7 WESTERN TANAGERS, 3+ RED-BREASTED NUTHATCHES, 3 WARBLING VIREOS (Garden and Battery), 4 PACIFIC-SLOPE FLYCATCHERS, 2 WESTERN WOOD PEWEES, 1 HOUSE WREN (Garden) and 1 BLUE-GRAY GNATCATCHER (Garden).

Waterthrush still present

Fort Mason this morning - Bobolink, etc.

David Assmann
 

The BOBOLINK at Fort Mason this morning was visible in one of the smaller trees behind the Battery, and then flew up into the Cypress trees behind the hostel and disappeared.  It was last seen around 9:25 am and Brian found his at 10:15 am at Fort Scott, so conceivably it could be the same bird. Otherwise Fort Mason had similar migrants as yesterday, with an increase in numbers of WESTERN TANAGERS (20+) and YELLOW WARBLERS (15+). There were at least four TOWNSEND'S WARBLERS, a HERMIT WARBLER, an ORANGE-CROWNED WARBLER (in Garden), a WESTERN WOOD PEWEE, a RED-BREASTED NUTHATCH, a LAZULI BUNTING and a WILSON'S WARBLER. A HOUSE WREN and a WARBLING VIREO were in the garden.
