Chestnut-sides Warbler @ N Lake

An otherwise quiet visit to GGP yielded a single CSWA with a mixed warbler flock at north lake this evening at about 5 pm. It was pretty chill, and I got to hang out with it for awhile. It was on the SW side of the lake, moving between the mainland and the southern island.

The male ORCHARD ORIOLE first seen on Tuesday morning was seen on Wednesday and again this morning. It's been moving around the garden. WESTERN MEADOWLARKS are moving through - saw 18 yesterday, including 16 in a single flock that landed in the Battery.  There were at least four this morning.  Two BONAPARTE'S GULLS flew by the Battery yesterday morning. The WANDERING TATTLER was joined by BLACK TURNSTONE on the abandoned pier yesterday morning. The number of WESTERN TANAGERS has declined fairly dramatically (6 yesterday, 5 today - down from more than 40 last Saturday.  YELLOW WARBLERS continue to move through (9 today, 19 yesterday). Small numbers of TOWNSEND'S WARBLERS, YELLOW-RUMPED WARBLERS, ORANGE-CROWNED WARBLERS and BLACK-THROATED GRAY WARBLER were also present both days. Yesterday a CHIPPING SPARROW was in front of the General's House, and 5 SAVANNAH SPARROWS were west of the garden.

Chestnut-sided Warbler low in poplars at intersection of paths, west end of Sue Bierman Park, now.

My first eastern warbler for the park this fall was a lovely-looking Chestnut-Sided Warbler feeding in the western section of the park. A Wilson's and Townsend's and a couple high-foraging unidentified warblers were also present, as was a Western Gull with a droopy wing. Wasn't there a droopy winged Western here in previous years?

Pelagic reschedule to tomorrow.

Alvaro Jaramillo
 

Folks,

  Due to poor weather for Saturday, we have moved up our pelagic to tomorrow (Friday). The forecast looks good for tomorrow! Lots of skuas have been around (multiple sightings last weekend), Black-footed Albatross, Black and Ashy storm-petrels, Tufted Puffin, shearwaters etc. This is a good time to look for skua, Flesh-footed (we had one farther south last weekend), and arriving Short-tailed shearwaters. If you are keen on a last minute pelagic on a day with a good forecast – do signup here:

or contact me for more information.

 

Looking forward to heading offshore!

Alvaro

BG, Ft Scott, Twin Peaks

An interesting day, with multiple uncommon to rare migrant/vagrants; too bad the round up didn't happen over one of the last two days.

Battery Godfrey was quiet compared to yesterday, with the highlight being the three ibis heading east over the bridge and the Bay before 9 AM, my first at this site.  Other species included a southbound harrier during the 7 o'clock hour, a couple of Red-taileds and a Coop, both south, 2 small flocks of Caspian Terns heading into the Gate, a couple of Parasitic Jaegers, a single Vaux's Swift, a single Western Meadowlark, and a zoom-by flock of roughly 30 Tricolored Blackbirds right over the Battery shrubbery.  Maybe a third were males, and all of them appeared to have white edges on the wing.  The low light was having a scolding flock of passerines in the lone big cypress, just as I was trying to leave.  They complained for 20 minutes about something that I could not locate from any angle, and I can't help but think that I missed what could of been the high point of an already productive day.

Ft Scott started quietly.  Felix arrived while I was craning my neck on the unseen scoldee, and after we gave up on it, we crossed over to the Fort.  After finding the sparrow flock, I eventually spotted a single Chipping Sparrow, likely one of those reported by Oscar yesterday.  While we were trying to refind the bird, I looked up to see a Lewis's Woodpecker flying away south over the buildings, a glossy black woodpecker with very deep wingbeats, clearly smaller than a crow.  There was also a male kestrel hunting over the grassy areas and 2 Say's Phoebes.  After Felix left, I doubled back to the ball field, and found a Willow Flycatcher hawking from the fence rather uncharacteristically, at least 8 Savannah Sparrows, and a Lark Sparrow.  While working the sparrow flock, I again looked up to see a number of raptors over the forest south of the Fort; in the group was a TV, a Red-shouldered, a Sharpie, and a White-tailed Kite, my first in SF this year.

After reporting that things were moving in the area, I left, and thus missed Jonah's Swainson's Hawk.  After a hydration rest at home, I then hit Twin Peaks from 12:30- 2:30, where a strong east wind made the weather tolerable for a while.  The highlight on TP was 5 Broad-winged Hawks, all apparently juveniles, and all heading south, a single and two pairs.  Two flew right over me, but they were so high that only the scope allowed good viewing.  I hoped the Swainson's would fly by, but if it did, I never spotted it.  Other species were few up there, with 1 northbound TV, 3 Sharpies kettling, many local Red-taileds, 1, 30 and 1 Vaux's Swifts, the last singleton was heading north, 6 Barn Swallows and a single American Pipit, both species were northbound.  I haven't done a Twin Peaks watch in several years, and it was nice to see the swifts at eye level.  When I got in my car, the temp read 102...

Breeding Ruddy Ducks and migration

Josiah Clark
 

Greetings Birders,
I was very pleased to discover six week old or so young Ruddy Ducks at Mountain Lake Park the other evening. This is only the second breeding effort there in perhaps 10 years, before that they were expected breeders.
Last year they attempted here but all of the young were quickly predated by Ravens, as is the new pattern with all precocial ducks, shorebirds and quail. The only other location in sf where this tule-reed obligate species nests is at Lake Merced.Not sure how their success is there. In general duck reproduction has plummeted with all species throughout the city over the last decade.
I’ve been checking the area for migrants now and then over the fall and last evening with Cedric we had the best flock I have seen of fall. We had seven species of warbler including hermit and Black-throated gray. Also 6 or so warbling vireos, a Western tanager, Western flycatcher and 2 osprey fly over. Presidio Hills had some decent numbers of returning sparrows including a lone savannah sparrow.
Definitely some sobering news stories about birds recently and a notably depleted migration for my memory. It motivates me to double down on my Habitat Potential efforts. Looking to make new headway this winter. The Young Birders in San Francisco and beyond are certainly bright spots in my Birding of late. I’m definitely grateful for their positive energy and help in the field, planting the seeds of change and tending the habitat of tomorrow.

Mount Davidson, Wed. 9/25

Adam Winer
 

Nothing rare in a very quick visit (7-7:50am) this morning:  in particular, no sign of Dominik's Black-throated Sparrow, though with my limited time it could still be around.

Very low numbers of migrants in general;  the most interesting migrants were 3 Vaux's Swifts headed south, a female Lazuli Bunting, a Western Wood-Pewee (the first I've run into this fall, though I think that says a bit more about how often I've been out than anything else), and a Savannah Sparrow.

Cheers,
Adam Winer

Lewis's Woodpeckers, Orchard Oriole and other sightings at Fort Mason this morning

David Assmann
 

A cooperative male ORCHARD ORIOLE on the west side of the garden was the first highlight of the day at Fort Mason. Later in the morning a LEWIS'S WOODPECKER was circling the Eucalyptus trees west of the garden.  I lost sight of it, but a few minutes later found two Lewis's near the top of a Cyprus tree in the Battery.

Other more expected migrants included at least 15 SAVANNAH SPARROWS, 3-5 WESTERN MEADOWLARKS (including one that sat at the top of the avocado tree in the garden for 90 minutes), 2 WESTERN FLYCATCHERS, 1 WARBLING VIREO, 1 CHIPPING SPARROW, 1 LINCOLN'S SPARROW, 3-4 ORANGE-CROWNED WARBLERS, 18 YELLOW WARBLERS, 8 YELLOW-RUMPED WARBLERS, 1 BLACK-THROATED GRAY WARBLERS, 2 TOWNSEND'S WARBLERS, and 15 WESTERN TANAGERS.

Re: Possible goshawk

Brian Fitch
 

While I did not observe diagnostic plumage details, I'm going to ID this bird as a juvenile female Northern Goshawk, based on the very large size and on flight style.  The size of a Red-tailed, mostly soaring, with only a few strong stiff wing beats, all buffy base color, strong streaking on breast and belly, broad based wings, strong white supercilium.  I did not note the vent for perimeter streaks, and the tail was folded.  I only picked her up when she was past me, allowing maybe a 7 second view before vanishing behind the cypress, heading a little east of southeast.  I saw several Coop's before and after for some sense of size comparison.

A number of birders were out in the morning, but I was alone when the Gos flew by.  Jonah joined me again later in the PM, and we had an interesting gull fly by that he got some shots of, so maybe we''ll learn more when its on a bigger screen.

Other species, highlights only:
Greater White-fronted Goose - 20+ over Marin, spotted by Hugh, 22 over the GG Gate midday
Turkey Vulture - 9 south, 2 north
Sharp-shinned Hawk - 3 south
Cooper's Hawk - 4 south
Red-shouldered Hawk - 1 north
Broad-winged Hawk - 1 light morph juv south
Red-tailed Hawk - 7 north, 8 south
American Kestrel - 1 female south, spotted by Jonah
dowitcher sp. - flock of 8-10
Vaux's Swift - roughly 10 viewed at great height, likely many more unseen
Western Scrub-Jay - flock of 25 winding north among cypresses

Dusky Flycatcher McLaren Park

Kevin Liberg
 

I saw what I believe was a Dusky Flycatcher at McLaren Park this morning. There were many ‘Western’ Flycatchers around but this empid was noticeably different in it’s dull coloration and rounded head. It made a call that sounded to me like a Dusky.
It was above the southwest corner of the lower pond. I was on the dirt trail just before the wooden boardwalk.

There's a HY Lark Sparrow currently inhabiting the entrance area of the Horseshoe Pits, just north of McLaren Lodge. Bird was very cooperative.
