Date   
Local Interest this week - Palm Warbler, Green Winged Teal. etc

David Assmann
 

Monday I made my third trip of the month to Mountain Lake to again search unsuccessfully for the Black and White Warbler.  I did see at least four GOLDEN-CROWNED KINGLETS and a NASHVILLE WARBLER. One PINE SISKIN was foraging in a blossoming tree. On Tuesday morning, at Fort Mason, after seeing a BROWN CREEPER climb up a Palm Tree, I noticed wave after wave of AMERICAN CROWS focusing on the trees near the tennis courts.  After a few minutes of non-stop agitation by 92 crows (I counted), a RED-TAILED HAWK flew over to land on top of the Chapel carrying a large all white DOVE https://www.flickr.com/photos/davidasf/40400027461/in/dateposted-public/ The hawk essentially ignored the crows, although it did duck a few times as they flew within inches. Later I joined Bob Gunderson in the garden to view one of the continuing WHITE-THROATED SPARROWS, as well as the continuing YELLOW-SHAFTED NORTHERN FLICKER.

This morning I started the day at Heron's Head Park, and found the continuing GREEN-WINGED TEAL in the largest of the ponds south of the main trail (it wasn't there when I first arrived, but an hour later it was). I then went to Lake Merced, where at least a dozen TREE SWALLOWS were flying over the north lake.  The PALM WARBLER (presumably the same one found by Dan Murphy), was foraging just west of the Boat House. My final stop (30 minutes) was at North Lake, which had nothing unusual, but it was nice to hear a PURPLE FINCH in full-throated song.


Sutro Seawatch 2/22/18

Dominik Mosur
 

Very cold this morning with w/nw winds 10+ mph, seawatching 7-8:15 from the observation deck.

Most noteworthy were (5 possibly more, definitely at least 4)

NORTHERN FULMARS - dark morph in view from 7:10-7:15 just beyond Seal Rock, 3 dark morphs flying north in a line ~ 7:20 just past the rocks observed simultaneously, light morph south 7:25 beyond the rocks, dark morph north halfway to horizon 7:59

BRANT - 2 and 2 north about halfway out 8:05

A good sized feeding concentration of hundreds of gulls, Brandt's Cormorants and Red-throated loons were on the water just beyond the rocks until about 8 a.m. when most peeled off with increasing winds and took off north/northwest in direction of the channel.

A pod of 4-6 Bottlenose Dolphins passed by beyond the rocks as well, maybe same group that's been observed previous recent seawatches from here.

We did have a number of good birds on this cold, crisp, breezy morning.

But the delightful bird at Sunset Circle was a male Hermit Warbler, not a Hermit Thrush!

There was a Hutton's Vireo in the willows along the concrete bridge a few months ago.  The species seems to be doing pretty well in the city recently, as I also had a first sighting from my home on Noe St a year or so ago.

I wonder if the chip note I heard was the Palm that Dan mentions.  Funny that I didn't cross paths with the group, but I was focused on birds, and wasn't looking for a Murphy's Mob on a Monday.

Good Birding,
Brian

16 GGAS members and friends birded around Lake Merced this morning.  Species wise it was a slow day with only about 50 species.  But the quality of those birds was pretty nice.  Among our first half dozen or so birds at the Sunset Circle was a male Cinnamon Teal and a male Hermit Thrush.  Both species have been previously reported from this area, but both were quite a surprise.  The teal was swimming along the marsh to the NE of the bridge.  The Hermit Warbler was in the Monterey cypress along the edge of the parking lot looking down at the bridge.  Among our last birds were a Palm Warbler and a Hutton's Vireo by the old boat launching site near the Boathouse.  They were along the hillside below the street parking on Harding Dr.  It's where the Lucy's Warbler was seen several times. I don't think the Palm Warbler was previously reported.  The Hutton's Vireo was cool because it's a fairly unusual bird that I don't recall seeing around there previously.

Another slow moving (for me) morning around Lake Merced today. 

The highlight was a Merlin that flew by at ankle level two feet away from my feet.  It blasted through from near the Bufano penguin statue, followed the trail until it came to the concrete bridge rail, and then swept up and out of sight.  I assume it was hunting the sparrow flock that frequents the trail side, but it didn't catch anything in that pass.

One of the drake Cinnamon Teal was at the wooden bridge, and three local Red Crossbills flew over northbound.  Two Soras called from each side of the wooden bridge, and the only swallows were Trees, at both ends of the lake. 

The lowlight was a dead female Ruddy Duck laying by the bench nearest to where the Lucy's was last fall.  Speaking of which, there was an unusual warbler chip in the trees there, but I wasn't able to see it before it went silent and got away in the large numbers of Yellow-rumpeds.

Fort Mason Yellow-Shafted Flicker, etc.

David Assmann
 

Participants in today's Golden Gate Audubon field trip at Fort Mason were able to see a WANDERING TATTLER walk along a ledge at the edge of Aquatic Park from a distance of no more than 8-10 feet, with the bird being unconcerned about the people with binoculars a few feet away. We also got great scope views of an ALLEN'S HUMMINGBIRD on a nest on the nearby hillside. A number (6+) of NORTHERN FLICKERS were in the garden, including a male YELLOW-SHAFTED, which posed on a branch of a Eucalyptus tree for 5+ minutes before flying, showing off its yellow feathers. A WHITE-THROATED SPARROW landed right in front of the group and foraged on the ground in front of us. At the beginning of the morning, a BROWN CREEPER was climbing up the large evergreen tree near the entrance to the garden, and a RED-BREASTED SAPSUCKER put in a brief appearance. A DOWNY and a NUTTALL'S WOODPECKER rounded out the woodpecker sightings in the garden. One PINE SISKIN worked a flowering tree on the east side of the garden. By the time we got over to the tennis courts in late morning to look for the Yellow Warbler, the wind had really picked up and we could not find it.


Red-necked Grebe

Matthew Dodder
 

Led my Palo Alto Adult School birding class to Lake Merced and Sutro Baths today. Several Allens Hummingbirds at the lake along with a lone Brandt's Cormorant were very nice. At the Cliff House Rocks we spotted a Red-necked Grebe close to shore.

Heron's Head Ridgeway's Rail continues and other notes

Eddie Bartley
 

Science Saturday walk at Heron’s Head Park, Feb. 17, 2018, ~ 1 - 2 PM, post high tide: a group of 15 saw the continuing RIDGEWAY’S RAIL east end of the marsh (about the “eye” of the heron’s “head”, looking from the sky) actively foraging head deep in pickleweed. Other uncommon birds for this site included a male GREEN-WINGED TEAL and a female RED-BREASTED MERGANSER.

 

Also of note: nice pickup in American Avocet with at least 15 at HHP in a high tide roost; Noreen and I counted another 7 a bit later at Pier 94, many are well into pre-alternate molt. Aechmophorus grebes were pair bonding, no dancing yet but definitely lining up their dance cards.

 

Pier 94: very large number of gulls especially Mew Gull which we estimated at 325, perhaps staging up for northerly movements. Also one each of Herring Gull (in Hansen’s pond) and Iceland Gull east of north marsh. This Iceland Gull has light eyes as only a small percentage of this species exhibits but, otherwise, typical adult Thayer’s ssp.

 

Happy Trails!

It sounded like a yellow crowned night heron

Josiah Clark
 

Keep your eyes out tomorrow! Just heard: Flying over lake street, called 3 times, first time loudly and quite nearby them twice more flying north towards lobos valley.
Reminiscent of black-crowned “wok” call (which I am very familiar with) but not quite right as I heard it. This was more of a croak. Less than a minute later I played the the iBird pro “typical call”, it sounded spot on. The local great-horned owls call on...

Recent miscellaneous sightings, Corona Hill tomorrow

Dominik Mosur
 

Some sightings I found notable from the past few days:

2/7/18 -

Sutro seawatch (7-8:15 am)

Red-throated Loons - 1400+ northbound between 7-8 a.m.

Marbled murrelet - 2 north

Tree Swallow - 2 north

Tree/VG Swallow - 1 north


2/8/18 -

Sutro seawatch (7-8:15)

American Wigeon - unusual here for midwinter, flew in with a Red-throated Loon and landed on the water

Red-throated Loons - 400+ north, probably due to less wind and hazy conditions, this and previous day's totals likely represent regular (daily?) movement of the locally wintering population

Northern Fulmar - light morph north, in view for about 4 minutes as it appeared to fly into gate

A Common Raven was observed carrying nesting material into a pine in Golden Gate Park at Lincoln Avenue, between 23rd and 24th


2/10/18 -

Sutro Seawatch (7:20-8:30) shift from east to w/nw wind overnight

Red-throated Loon- 670 north , plus 800 distant loon sp.

Northern Fulmar - 3, two dark morphs, sandwiching a light morph about 5 minutes apart between 7:45 and 8 a.m. The last bird appeared to land just beyond seal rock where I lost it in the swells

Common Murre - 1760 north


2/15/18

Sutro Seawatch (7:05-7:50)

Red-throated Loon - 60 north, where did they all go, perhaps feeding somewhere else today (?)

Common Murre - 3000+ north, 1800 in first ten minutes, dropping off after 7:30



If you're looking to do some birding in a group tomorrow, join the 3rd Friday Corona Hill bird walk. Eddie Bartley has kindly agreed to fill in as a leader this month.
The group meets at the main gate of the Randall Museum, end of Museum Way. Muni 37 lines drops you off two blocks away. Walk starts at 8 a.m.

Fort Mason Local Interest - Yellow Warbler, etc.

David Assmann
 

The YELLOW WARBLER continues near the tennis courts today (also seen there on Monday).  The small grove of trees next to the tennis courts attracts many birds.  A BROWN CREEPER was in the grove and a RED-BREASTED SAPSUCKER flew in and landed at eye level. One WANDERING TATTLER was on the abandoned pier (also seen Monday).  A female BELTED KINGFISHER was also on the pier, and three BUFFLEHEADS, a RED-BREASTED MERGANSER, a RED-THROATED LOON and a COMMON LOON were in Aquatic Park. An ALLEN'S HUMMINGBIRD was on the slope above Aquatic Park (also seen Monday). On the steps down to Aquatic Park, a HUTTON'S VIREO was singing.  Did not see a WHITE-THROATED SPARROW in the garden today, but saw three there Monday.  At least one ORANGE-CROWNED WARBLER was in the garden.  Saw a total of 54 species.

On Tuesday, while in the Botanical Gardens, I ran into Juan Garcia, who spotted the RUFOUS HUMMINGBIRD east of the succulent garden.

This morning while doing my weekly beach/park patrol I counted 31 Snowy Plovers on Ocean Beach between Lawton and Irving after a two week absence. Possibly the big tides at the end of January disturbed their usual roosting spot around the end of Irving.

The goose flock was present at the Polo Fields with the Snow, Ross's and Greater White-fronted Geese. In October my count of Greater White-fronted Geese was up to 15.

Lloyd Lake had ten Hooded Mergansers which included five adult males, four females and one immature male. The annual Ring-necked Duck flock with the Lesser Scaup never made an appearance this year. The removal of some of the vegetation near the lake may have been a factor.

Ended up at the Botanical Garden with the expected birds. The area where the Rufous Hummingbird has been seen was being watered although there were at least a half dozen Allen's in different locations. The! Rufous Hummingbird was detected back in September but was not identified with any certainty until Ken Schneider and Lee Hong-Chang got definitive photographs in late October.

Good birding,

forwarding Lucy's Warbler at Presidio Golf Course

,..from Mark Dettling. Cheers, Peter

Lucy's Warbler (Oreothlypis luciae) (1)
- Reported Feb 13, 2018 08:50 by Mark Dettling
- Presidio Golf Course, San Francisco US-CA (37.7879,-122.4684), San Francisco, California
- Map: http://maps.google.com/?ie=UTF8&t=p&z=13&q=37.787921,-122.4684&ll=37.787921,-122.4684
- Checklist: https://ebird.org/view/checklist/S42728658
- Comments: "First seen around 9am in the willows at the bottom of the gully right at this spot (which is just east of Mountain Lake in the Presidio). It was with a flock of Yellow-rumps and Townsend's. I looked for the bird in this spot 20 min later, but the flock had moved on. At first glance it reminded me of a Bushtit since it was all pale gray with the underparts paler. The tail was too short and the bill too pointed. Then as it was moving about, it moved its wings to reveal a deep chestnut rump. As I watched the bird for a few minutes it began to preen showing the chestnut crown patch as well as the chestnut rump. Did not have a camera so no photos. I'm not on the SF birdlist, so someone might want to post my eBird list there."

I was hoping yesterday's blow would make for interesting birding off the Cliff house, but it was very slow. The Rock Wren was still south of the Cliff house near the graffiti face.

The Rufus Hummingbird was seen in the southwest part of the succulent garden in the Arboretum, there was also an adult male Allan's to make things interesting.

Think we may have seen a Nashville Warbler in the GG Botanical Gardens yesterday.  All bright yellow front, white around the legs, olive back and wings and white eye ring.
