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.

good call, Peter
I’ve never seen an immature black-legged kittiwake with those
underwing patterns.

Hi all -

This could be a first-year Red-legged Kittiwake.
Worth looking into in any case. Not many photos on line of underwings
of RLKI but here's one that shows a similar pattern:

yte1stS5Commanders1106.jpg>https://www.birdguides-cdn.com/cdn/gallery/b
irds/Red-leggedKittiwakeFlyte1stS5Commanders1106.jpg

Both the primary coevrts and the tertial area being marked dark. By
contrast I can't find a BLKI with either. February is the month for
RLKI in CA.

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

Hi all,

I had brief looks and managed a single photo of an immature
Black-legged Kittiwake seen just offshore from the Cliff House at about
0815 this morning. A bit more detail at my eBird checklist here:

cklist/S52301096>https://ebird.org/view/checklist/S52301096

I think the photo supports my ID, but I'm a little puzzled by the
apparent dark markings on the underside of the left wing (perhaps the
primary coverts?), which I don't see as expected in the field guides I
checked... comments welcome.

Good birding!

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.

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

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!

Pigeon Guillemot in the Bay

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.

Black Throated Green Warbler @ Stow Lake/Strawberry Hill

Ken Moy
 

Saw 2/3 post on eBird from Jonah Benningfield for this bird @ Stow. Went out on 2/8 and met Ruddy Wallenberg who informed me that the bird was seen on the easternmost island where the great blue heron's nests are sited. Went out again on 2/9 and spotted the bird on the island around 11:30 am from Strawberry Hill at the bench just north of the base of the waterfall. It was very active in the open and afforded several good looks before if went back into the thickets in the center of the island.

Good birding to all,

Ken Moy

Correction on Pigeon Guillemot Sighting

Joachim Gonzalez
 

After reviewing, I have concluded that the mysterious Alcid was a Marbled Murrelet that was out close to the channel.

R-n Grebe, etc.

Brian Fitch
 

This morning at the Sutro Baths, a single Red-necked Grebe spent some minutes slowly fishing its way from North Rock eastward around Land's End.  There were also four female Common Goldeneyes, 1,2,and 1, all heading north and then into the channel as well.  There's quite an uptick in this species presence in unusual spots this winter.

Also interesting was a single song phrase from a male Wrentit at Ft Miley East, between the Legion and the VA Hospital, along with a small flock each of Western Bluebird and Pine Siskin.

Presidio Great Horned Owls

the Presido has a hawk/owl cam set up

Anyone know the exact location? I’d like to check these owls out in person

Re: Presidio Great Horned Owls

Many people would like to check them out in person. For that reason, they are not disclosing the location to avoid disturbing the owls.

I appreciate the need for not disturbing the owls
I will be viewing the nest from afar with my high powered binoculars. I already figured out the location from the YouTube live Cam

Black Skimmers at Fort Mason Yacht Harbor fide Jonah Benningfield

Logan Kahle
 

Hi all,

Just heard from Jonah Benningfield that there are currently 2 Black Skimmers at the Fort Mason Yacht Harbor. Don't have any details on specific location (maybe on the breakwall?), but given the nature of Skimmers in the city it is likely best to chase these birds soon if you want a shot at seeing them.

Good birding,

Logan

Red-necked grebe baker beach

Josiah Clark
 

Went out to see what the storm dragged in at Baker Beach. A stealthy red-necked grebe was in with increased numbers of scoters nearshore. 710 red-throated loons flew out of the gate during a calm period, presumably seeking shelter in the bay. Also very out of my norm for my yard at my recently re-activated feeder, a very tame male brown-headed cowbird. I’ve looked for the eastern phoebe many mornings in the last couple weeks but no sign of it.

Re: Black Skimmers at Fort Mason Yacht Harbor fide Jonah Benningfield

Jonah Benningfield
 

Hi birders,

Ok, here's the story with the Skimmers.
This afternoon, during my sailing practice (around 5:20), I was headed out of the Golden Gate Yacht Club harbor, when I saw a flock of medium-sized shorebirds flying overhead, possibly BBPL, but I don't really know. Anyways, while I was tracking those as they flew west, I got on (2) BLACK SKIMMERS flying east over the rocky spit (with the Wave Organ at the end).

Their bouncy flight style, long wings, partially orange bill, and entirely black upperparts with white undersides were all visible, even though I had no binoculars. They were flying east, towards Fort Mason, although I quickly lost them as we sailed away. I tried and failed to pick them out from a distance over the next hour or so, and on my way back into the harbor I didn't see them, although by that point it was very dark and pouring rain. However, I suspect that they flew into the Bay, rather than sticking around so close to the gate, and I would suggest checking potential roosting spots (Bayside?) if one were to look for them in SF. That said, I'll be out on my bike tomorrow before and after school (when it's not pouring), and I'll bring along a camera just in case.

all the best, and good birding,
Jonah B.

Thank you, Josiah! What time of day did the RTLO fly out of gate?

Skimmers at Crissy

Yo,
Two BLACK SKIMMERS (presumably the same two) are hauled out at Crissy. I’ll chill with them for like 15 mins if anyone’s nearby.

Re: Skimmers at Crissy

Aaron Maizlish
 

The two black skimmers are sitting at the end of the platform at the entrance to the Saint Francis Yacht Harbor. You can walk out to the end of the wave organ, or you can be lazy like me and see them from the end of the Marina Green parking lot. I suppose if you are exceptionally skilled with binoculars you might be able to see them without rolling to a complete stop. Thanks, Jonah
