Date   
Cliff House Sea-watch, 5/27: Parasitic Jaeger et al.

Paul Saraceni
 

This morning (5/27, 7:00-8:15), Hugh Cotter and I did another sea-watch from the Cliff House terrace.


Winds were again out of the W-NW, though significantly lighter than yesterday.  Birds were in smaller numbers than yesterday, and there were no near-shore feeding frenzies.  But there were still some interesting sightings.


At 7:10 I observed 2 RHINOCEROS AUKLETS flying N, then turning NW further out to sea with a group of 8 Common Murres.


At 7:35 we observed well an adult PARASITIC JAEGER flying N out from the rocks, then turning NE and heading into the Golden Gate Channel.  While this nearshore jaeger is rather early (we typically do not observe them from shore in SF until mid-late July), perhaps its occurrence is less surprising in light of the recent incursion of Elegant Terns.  


Speaking of the latter, we observed 40+ ELEGANT TERNS this morning, all concentrated within the GG Channel and visible from various coastal points (including Battery Godfrey).


There were 5 HEERMANN'S GULLS observed this morning, including an alternate-plumaged individual, and 1 imm. Glaucous-winged Gull.


There was a small movement of loons flying N, including 1 Common and 8 Pacifics.  There were also 4 Surf Scoters flying off the Cliff House and 6 observed on the water below Battery Godfrey.


A quick visit to the East Wash and Ft. Miley produced a Swainson's Thrush singing from an open perch near the top of the Wash and a pair of Cooper's Hawks engaged in a courtship display-flight.

BLUE GROSBEAK Corona Hill 5/30/2019

 

There's a male BLUE GROSBEAK coming to feed periodically in a cotoneaster on the south east face of Corona Hill.

Caveat. The bird is in an area not readily visible from public trails and it will take lots of patience to get a look. It's loud call note CAN BE HEARD from the garden in front of the museum, the area behind the museum where the Indigo Bunting was two weeks ago, or from the trail next to the fence on top of the hill looking to the southeast.

Good luck,

Grosbeak visible

It just perched on a rock and then on top of a spruce? tree - out in open for almost a minute.

Before Dominik's timely post of the Blue Grosbeak sighting, I started the day at Fort Mason, where the only migrant was a WESTERN WOOD-PEWEE in the Battery,  At the Palace of Fine Arts, the two resident MUTE SWANS were zealously guarding six chicks as the roamed the lawns. And at El Polin Springs, the OLIVE-SIDED FLYCATCHER was still calling.  Also saw a newly fledged HUTTON'S VIREO.  However, the BLUE GROSBEAK at Corona Heights stole the day (pictures attached).

Thanks to Jim Lomax for the early bird report from the field.

Close up phalaropes

Aaron Maizlish
 

If you want close viewing of Red-necked Phalaropes, at least five are swimming around the boat docks at the Pacific Rowing Club, S. Side of entrance road to Harding Golf Club at Lake Merced. One is about three feet from me. Nice, but no unusual gulls here at the moment.

Started the day at Fort Mason, meeting up with Juan Garcia.  No new migrants today.  Unfortunately someone vandalized the tree in front of the tennis courts, tearing off the limb that contained the active Nuttall's Woodpecker nest, presumably dooming the young. Moving on to El Polin Spring, the news was better.  The continuing OLIVE-SIDED FLYCATCHER has found a mate! The male was no longer singing, and was making courtship calls as the two flew around the trees above the parking lot. A few migrants were found as well, including a WARBLING VIREO, a WESTERN TANAGER, and a LAZULI BUNTING.  Final stop was Crissy Lagoon to look for a Red-Necked Phalarope, which wasn't there, but the surprise bird was a male BLUE-WINGED TEAL south-east of the bridge.

Still on NE hillside slope @ 8:40. In the open. Also, Ash throated flycatcher & warbling vireo.

Ash Throat Botanical Gardens

Joachim Gonzalez
 

On a relatively slow day in the Botanical Gardens, Nicolas F, Max B, Sabrina C, and I found an Ash Throated Flycatcher near the succulent garden. It was quickly mobbed by a Black Phoebe and flew towards Cali Native section. Nothing much else of interest. Cooperative Allen’s was also good.

I know this is really a San Francisco County sighting but I’m not on that listserve. Feel free to forward.

To our astonishment, a pair of adult Ancient Murrelets with a roughly half-grown chick spent much of today just off the East Landing at Southeast Farallon Island.  Ancient Murrelets are not known to breed south of southern British Columbia or perhaps the Washington coast.  This species takes their 1-2 chicks to sea when they are only 2-3 day old downy fluffballs.

The murrelets were seen from both boat and shore.  In the late afternoon, we watched from the island as the two adults made repeated dives, coming up with food that was fed to the chick.  Very fascinating!

Murrelets take their chicks far distances. Given the size of the chick, I doubt it originated from Southeast Farallon.  But the origin will be fun to speculate and discuss.

U.S Fish and Wildlife Service volunteer Michael Pierson got lots of great photos. A couple are included in his ebird checklist from the day, which have birds from the Golden Gate to the island. Attached is a link to Michael’s checklist, shared with me.

Brown Boobies continue out here. One was on Sugarloaf today.

Hit some very foggy spots along the west side today with Paul Saraceni for much of it.
Not much doing but interesting sightings included:

Eared Grebe - Continuing at the South End of Lake Merced

Four Sanderling on Ocean Beach - late migrants or returning birds ?
Two GW Gulls continuing.

East Wash/ Fort Miley had three singing Swainsons Thrush.

Two BH Grosbeak at El Polin

Some belated sightings from earlier this week included two and possibly three BG Gnatcatcher's, a lingering Townsend's Warbler and a flyover GT Grackle at Battery Godfrey on Tuesday May 28th.

Hi birders,

Blue Grosbeak still very cooperative on and off for a couple hours (say some other birders checking him out for a while) on the north side of Corona Heights park at 5:45pm 6/2. Walk uphill past the dog run and turn the corner. He’s favoring the scotch? broom thickets vs the poison oak/blackberry.

Cheers,

The Blue Grosbeak

Dave Weber
 

Glad the Blue Grosbeak continued at Corona Heights Park where I found it early this morning. Corona Heights is one of several locations in the city new to me in the last few weeks, the others being Candlestick, McLaren, Mt D and Twin Peaks. I would not have visited them if I had not been nearing 250 county birds. The Blue Grosbeak was #250. Nearly every new county bird these days has been found by others who check these location regularly. Thanks to all of them.

Re: Blue Grosbeak

Lucky Daniel - he arrived just after the Blue Grosbeak popped out into the open. Cliff Y had been following the bird for perhaps two hours when I arrived at about 5:15, and a few other observers came by as well. The Grosbeak had been scared off by Scrub Jays but returned to favored hiding places in the shrubs and adjacent perches, eventually venturing out onto the north slope grasses to graze. Moderately cooperative - it kept its distance and would not allow Cliff to get close-ups, but it remained in view intermittently for at least a half hour, silent, later settling down and feeding on seeds.

Also of note: a House Finch was hover-feeding - repeatedly hovering over the tall grasses as they blew about in the wind to grab seeds. First time I've seen such behavior from this species.

The Blue Grosbeak flew into the reported location, as described by Dan Scali, from the south at 10:34 a.m. Was not present earlier. Calling chip notes and feeding on the grass seed.
