Pigeon Guillemot in the Bay

Joachim Gonzalez
 

This morning on a bird walk at crissy, there was a Pigeon Guillemot right by the Golden Gate Bridge. 1 Pacific Loon was also in the bay.

Hermit Thrush takes brisk bath in Glen Park garden

Roberta Guise
 

At 5:15pm today a Hermit Thrush popped in, splashed around in the bird bath for a long minute, gave itself a good hard shake then flew off.

Reporting a couple of days late: Wednesday at 6:30 Wed AM just as a cloudless dawn was breaking, a Great Horned Owl hooted from the pines up Poppy Lane/behind our house. Jupiter was brilliant, and the even brighter Venus tracked slightly later. What a way to start the day!

Good birding and skygazing!

Registration closes the Wednesday before.

Black-throated Green seems to continue

Jonah Benningfield
 

Max Laubstein is on a rarity streak today!!! We pulled up at Stowe about 15 minutes ago, and he quickly and effortlessly spotted a Black-throated Green Warbler, presumably the same individual first seen by Alan Hopkins last spring, and again by Brian Turner and Friends last fall.

Rudy Spotted a merlin, headin quick to greener pastures.

Peeking Ducks continue as well. Nice grab by Oscar T. Moss.

Toodles,
Jonah

Adult Kittiwake at Sutro Baths

Jonah Benningfield
 

Oscar and I are seawatching from the Cliff House. Adult Black-legged Kittiwake just flew right over us. Completely yellow bill, small black wingtips, and grayish facial spot seen well.

good birding,
Jonah B.

Yes, the third photo you sent is of a Black-legged Kittiwake. Structurally the legs are too long, eye too small, and bill too large. On plumage the mantle is too pale, and the wing markings more intense than on Red-legged.

Thanks Joe and Al -

You are probably correct. All of my seabird reference books are boxed up at the moment so all I had was on-line images. There are some of young and winter adult RLKI that appear to show dark tail tips and/or hind collars:

http://orientalbirdimages.org/images/data/redlegged_2.jpg
https://www.naturepl.com/cache/pcache/08135133.jpg

but at least the dark-tipped tails are probably mis-identified BLKIs (e.g., 3rd photo above) as I recall this field mark now that you mention it.

Hard to explain this as oiling, especially the primary coverts, but perhaps this is what it is.

Hi all -

Worth looking into in any case. Not many photos on line of underwings
of RLKI but here's one that shows a similar pattern:

Both the primary coevrts and the tertial area being marked dark. By

Thought it worth mentioning in case others want to go look for it.

Interesting possibility. My understanding is that immature Red-legged
Kittiwake does not have a "broad, dark hind collar" or a dark tip to the
tail.

post storm Pelagic

Alvaro Jaramillo
 

Hello folks

    The oncoming storm made us shift our sold out pelagic from Saturday to Sunday. This change has opened up some spots. The winds will be dying down Saturday night, and weather will be calming throughout the day on Sunday. We plan to scour the inshore areas early on in the day looking for alcids and Black-legged Kittiwake, and then head out farther offshore to see if we can find albatross. This time of year is excellent for Laysan Albatross if we can get to the albatross habitat. Post storms, you never know what could be out there. At the Morro Bay Bird Festival a couple of weeks ago post storm we found Laysan Albatross as well as an out of season Buller’s Shearwater in addition to great looks at Short-tailed Shearwater, and Black-legged Kittiwakes. Many of the Common Murre and Rhinoceros Auklet were in fine breeding plumage. We hope to be able to find some nice stuff this Sunday.

early breeding behavior

 

On 1/30/19 a female ALLEN'S Hummingbird was constructing a nest inside the fence of the reservoir at the Menzies "California" section of the Arboretum/Golden Gate Park. Off top of my head this is the earliest nest building I can recall by Allen's Hummingbird in recent years with a mid-February being the next earliest on Corona Hill some years back. The nest was being built in a blackberry bush.

This morning (2/1) while heading into work I observed a pair of BAND-TAILED Pigeons engaged in stiff winged courtship flights and chasing over the intersection of Clarendon and Laguna Honda. This species has yet to be "confirmed" with physical evidence of nesting in San Francisco but this is the second consecutive winter I've observed Band-tails engaged in this behavior at this site.

The AMERICAN BITTERN continues at North Lake, still in the same spot.  A GREATER WHITE-FRONTED GOOSE was in with the CANADA GEESE on the Polo Fields in Golden Gate Park.

Sutro & L Merced

Brian Fitch
 

Two female Common Goldeneye's were swimming south of the concrete bridge this morning at South Lake Merced, an unusual site for this species.  Singles of Virginia Rail and Sora were visible in the reeds at the NE end of the bridge, and approximately 15 Great-tailed Grackles lifted up out of the reeds around 7:30 and headed off to shop at Westlake.

Last Thursday, three Red Phalaropes flew by the terrace at the Sutro Baths, while six Marbled Murrelets flew into the Gate at differing intervals.  There were over 200 Red-throated Loons, many on the ocean, and many more flying north.

A WILSON’S WARBLER is high up in a Poplar tree near the center of Sue Bierman Park - presumably the same Bird seen by Mike Carozza in December. There was also at least one WHITE-THROATED SPARROW.
