Date   
Black-throated Green Warbler today, Stow Lake Drive East, G.G.P

Lee Guichan
 

Hello everyone,
Black-throated Green Warbler showed up again this morning in the Pittosporsum large shrub or tree (has wavy leaf edges with something that look like  clumped berries)  this morning at about 11:30am - 12pm. I was with a couple of Townsends's Warblers. It stayed in the Pittosposum until we lost it, the shrub is nest to a lower shrub with large leaves& small white flowers.

Location is the same as I posted yesterday. G.G. P, Stow Lake East, It was past Stow Lake Roman Bridge, South side just past the Great Heron Colony island, Pittosporsum is on the North side of the street.
(Yesterday about 2:25 in was seen in the Willow that has hanging branches above sidewalk.)

Ken M. spotted it, Nancy P., & I were also scanning trees next to him. We were joined by Dan & Joan Murphy, & Angie, great views of the Black-throated Green Warbler.  
Thank you Brian Tuner who found the Black-throated Green Warbler on Mon. 22nd at Strawberry Hill. 

About 12:30pm a small flock of birds flew into the Pittosporsum among the flock was the
Blackburnian Warbler (found by Angie Geiger over one week ago) which has been seen mostly in the large Oak tree along the Log Cabin trail near east side of the large lawn.


Good luck!

Mark,

Just in case no one else responds in time.

I haven’t been over to see the Black-throated Green Warbler this week, but Lee Guichan described exactly the same trees that this bird was at in April this year when it was in breeding plumage:   

37°46'10.8"N 122°28'22.1"W


I saw it in the Pittisporum(?) on the north side of the road and the willow-like tree on the south/lake side of the road.   Also from her description birders were looking for it on the Log Cabin Trail which is down the slope (North) of this spot.  Note that it was first spotted on the island both in April and this month, probably because the island is birded more frequently than these trees, which is probably where it mostly hangs out.

Good luck to you and Lucas.

Re: Black-throated Green Warbler at Stow Lake.

Joe Morlan
 

The singing male last April was outside of the expected vagrant window for
this species. Spring records are usually much later from late May to early
June. It is possible that it may have spent the winter undetected until it
started singing. This species winters occasionally in Southern California,
sometimes with the same individual returning in successive years. It will
be interesting to see if this bird sticks around this winter. Please keep
the reports coming!

Hi Birders,
     As a correction, Lee has kindly reminded me that she did not see the BTGW on Strawberry Hill yesterday, but rather found it along Stow Lake Drive. Sorry about that!
      We don’t often get to see the same individual rarity in spring and fall, making this well-photographed bird so interesting. Searching Ebird’s illustrated checklist might be useful to anyone interested in making comparisons, studying a potential hybrid or molt.

Returning Black-throated Green Warbler at Stow Lake today.

bitanangan
 

Hi Birders,
     Thanks Brian for initially refinding this bird, found again today by Lee Guichan on Strawberry Hill and later by Reef (apologies, don’t know your last name) in an oak along the Log Cabin Trail, and later still by David Tomb when it flew to a familiar haunt in a clump of trees along Stow Lake where I was finally able to catch up with it.
    But how can this be the same bird seen a few months ago last spring, then found in the exact same place sporting a rather solid black throat while this individual today, in a quick live glance at a very hyper-active bird or even of a photo, have an apparent grey throat yet still briefly flashing, from a certain angle an almost subtly iridescent faintly there, then not, black throat?
     If Jon Dunn and Kimball Garrett can be believed on page 306 of their Peterson Field Guide to Warblers in a statement is made regarding molt in fall males: “...black on the throat and breast is heavily veiled with white tips...” which explains why a bird with an apparent grey throat might really have a black throat! I don’t readily know these things, just sharing some quick, basic follow-up research this evening that some of you might find interesting.
     The continuing Blackburnian Warbler and a White-throated Sparrow were also seen along the Log Cabin Trail.

Is this the same place where a singing Black-throated Green was seen
13-25 April 2018? Same bird returning?

Black-throated Green Warbler, Stow Lake, G.G. P.

Lee Guichan
 

Hello,
I re-found the Black-throated Green Warbler (Brian Turner found yesterday at Strawbery Hill) at 12:15pm, today at Stow Lake Drive East, it was on both sides of the street, but most on a large shrub with leaves that curl, on the North side of the street. Nancy P. & I observed it for about one minute while it preened. It was past Stow Lake Roman Bridge, south side just past the Heron Colony island.
There were two Townsend's Warblers & one Yellow -rump Warbler in the tree  that had long thin leaves

I alerted the other birders photographers who were at the lower Log Cabin Trail looking for the Blackburnian Warbler, but we could not re-find the Black-throated Green Warbler.

Then about 2:25pm it was re-spotted among the group including me, that returned to the location where I had found it earlier, it was it a tree that had long thin leaves. Eight observers got to see it. There were three Townsend's Warblers, & two Ruby-crowned Kinglets
Do not know the name of the trees.

Earlier in the morning the Blackburnian continued in the large oak at the lower Log Cabin Trail.
Log Cabin Trail : Six Ruby-crowned Kinglets, one Brown Creeper, one Townsend's Warbler, One Downy Woodpecker, & two Orange-crowned Warblers.

Later in the large Oak & smaller Oak trees, one Red Breasted Sapsucker, eight Townsend's Warblers,    

Thank you Brian Turner for finding the Black-throated Green Warbler.

Good Birding,

Lots of activity this morning, although nothing rare. I counted BROWN PELICANS passing by for 30 minutes, and counted 432 - the stream was constant. A MERLIN scared some RED-MASKED PARAKEETS in the Battery.  There were two HOUSE WRENS - one in the garden and one in the Battery. Also two RED-BREASTED SAPSUCKERS. A NASHVILLE WARBLER continues in the lower Battery. Saw two WESTERN TANAGERS (Battery and Garden). There were seven WESTERN MEADOWLARKS on the Great Meadow. Just before I left seven WESTERN BLUEBIRDS flew in east of the garden.

Probable Black-throated Green Warbler @ Strawberry Hill

Brian Turner
 

Bird was in alders to the east of the bridge at top of falls. First noted bright yellow face. Breast was whitish with black streaks, concentrated towards head. Faint yellow wash in vent visible in a series of "binocam" pics in EBird list. These are a bit overexposed and I'm hoping someone with a better camera can verify. 


Good birding,

10.21.18 Sea watch from South end of OB- Long-billed Dowitcher

H Cotter
 

I spent approx 90 minutes sea watching from the south end of Ocean Beach this morning- 10/21. Seabird highlights were few - the primary highlight was a mixed flock of shorebirds - approx. 25 dowitchers and a single Dunlin that flew past. These were the first Dunlin and Dowitchers I have seen all fall. One of the dowitchers appeared to be a Long-billed with a significant amount of rufous visible all the way down.
A single Marbled Murrelet was the other highlight.
Numbers of Scoter, Western Grebe and Loons have increased in the last week.

Today, Sunday October 21, the Blackburnian Warbler continued in the trees below Stow Lake and east of the log cabin and Pioneer woman statue.  Thanks to Michelle and others for putting my wife, Rosita, and me in the right area.

We later walked east of the conservatory of flowers and found the location described to us by Michelle.  In just a few minutes the Chestnut-sided Warbler was found by Rosita.  We both watched it for an extended period.  Michelle joined us by bike after about 10 minutes and we showed it to her, too.  This was all from about 11:30 AM to 2:30 PM.

Possible Nighthawk and other sightings at Fort Mason

David Assmann
 

A very active morning at Fort Mason, with the most intriguing sighting coming at the very end when three of the participants in this morning's GGAS walk flushed a medium sized (bigger than a towhee) brownish bird that was sleeping on the ground in the northeast corner of the garden. It was described as having spots, a white bar on each wing when it flew, and sharp pointed wings, which sounded like a Nighthawk to me. The bird flew towards the apple tree when it was flushed, and we could not refind it. Prior to that we had a very good morning for sparrows, with nine species altogether. A LARK SPARROW and a CHIPPING SPARROW were on the north side of the garden, and a CLAY-COLORED SPARROW and a LINCOLN'S SPARROW were in the garden, Warblers included a NASHVILLE WARBLER in the lower Battery, and a PALM WARBLER on the lawn north of the garden. An OSPREY was over the Bay, and a WANDERING TATTLER was on the waterfront. Three WESTERN MEADOWLARKS were west of the garden.

SW SF: Red Knot et al., 10/20/18

Paul Saraceni
 

This morning I did a seawatch (7:15-9:30 AM) from the south end of the Great Highway. Viewing conditions were very good with overcast skies and glassy seas to begin, with light W/SW winds that gradually increased.


The highlight was a basic-plumaged RED KNOT flying N over the surf just off the beach.


Hundreds of gulls -- mostly Californias and some Westerns -- were on the move N the entire time, loons and W. Grebes have increased in numbers, and Elegant Terns were completely absent while I was watching.


Other observations of local interest:


Greater Scaup 1 f. (flying N with Surf Scoters)

Surf Scoter 45

W. Grebe 60+

Eared Grebe 1 (flying N over the ocean)

Common Loon 11

Pacific Loon 22

Red-thr. Loon 28

Long-billed Curlew 5 (fly-bys)

Marbled Godwit 3 (flying with 2 L.-b. Curlews)

Sanderling 250+

PARASITIC JAEGER 2 (flying N)

POMARINE JAEGER 1 (flying N)

Common Murre 15

Hermit Thrush 1 (calling from across the Great Highway)

Also: Harbor Porpoise 4


After that I headed over to the south Lake Merced concrete bridge for a short visit, where there were other birders present. Species I personally observed included: 2 Green Herons, the continuing Greater White-fronted (2) and Cackling (2) Geese, 8 Eared Grebes, a calling Sora, and a Warbling Vireo and a Black-throated Gray Warbler in a mixed flock in the willows near the fishing pier.  There were hundreds of gulls on the lake, mostly Californias with lesser numbers of Westerns. In a quick scan of the flock I also observed 1 Herring, 2 Glaucous-winged, and 1 sub-ad. Heermann's Gulls.

American Redstart at Concrete Bridge

A gorgeous adult male American Redstart is very active around the east end of the concrete bridge at Lake Merced. Jim Chiropolos first spotted it up by the penguin statue, it is currently working the willows around the bridge. I had never seen an adult male in the city, quite a striking specimen.

Red-naped Sapsucker, G.G.P., 18th Oct.

Lee Guichan
 

Hello,
Yesterday near the Fuschia Dell while looking at the Chestnut-sided Warbler at 10:15 am, the Red-naped Sapsucker flew into the same tree that the Chestnut-sided Warbler has been seen in, it stayed for three seconds & flew out.
I thought it might go the the Plane tree or Sycamore tree, where I saw it in on Oct. 13th, sure enough, 6 minutes later it was in the Plane tree. I watched it for ten minutes while it drilled & flittered on several very high branches.

The location is on the lawn area, walking East toward McLaren Lodge, there are two Plane or Sycamore trees (leaves are large, with fall foliage), John F. Kennedy Drive, paved path off of JFK Drive, path is closer to shrubs where the upper trail is closed, there are two benches, (bench that has the plaque in memory to John H. Johnson) the tree in front of that bench is where the
Red-naped Sapsucker was.  

There were three Townsend's Warblers, two Yellow-rumped Warblers also in the tree.

Good birding,
Lee Guichan

Continuing warblers

David Assmann
 

Haven't seen a mention of these since the 16th - the BLACKBURNIAN WARBLER on the east side of the meadow next to the Log Cabin trail in Golden Gate Park, and the CHESTNUT-SIDED WARBLER on the west side of the East Conservatory Drive (near the Fuschia Dell) gave fine views to both myself and Lee Guichan this morning. It's the 8th day for the Chestnut-sided and the 7th for the Blackburnian.
