possible Jaeger at the Marina Yacht Club Harbor?

Steven Lewitzky
 

Hi Peoples,

This is my first post here and i am somewhat new to birding so please accept my apologies in case this entry makes no sense.

I was birding with a friend at the Golden Gate Yacht Club near the Wave Organ where we spotted a very dark bird chasing an Elegant Tern in flight. This bird was a strong flier as it seemed to easily catch up to the tern even with the tern's amazingly evasive maneuvers.
We could only guess at the bird's motives (an attempt to steal the tern's non-existent catch?) but after several assaults it landed on the water and took a bath.

It had an almost white bill with a black tip and had white feathers under it's primaries.
does anyone have any ideas what this could be?

I tried attaching a photo, but here's a link:

Thanks!

Steven

The Pec was also present at about 6 PM.
There was also a Wilson's Snipe in the pickleweed on the North west side of the lagoon.


At around 5.40 PM from Crissy a large flock of approx. 75 Greater WF Geese were towards the east bay flying high heading south.

During yesterday's Rare Bird Round-up, Brian Turner and I observed a BLACKPOLL WARBLER at the summit of Mt. Davidson around 8 AM. After foraging in a euc, the warbler flew off to the south.

Other birds of local interest at Mt. D. included 1 Willow Flycatcher in the East Bramble, 3 House Wrens (4-trail X, Ravine, north slope), 1 Bl.-thr. Gray Warbler (summit), and 1 Bl.-head Grosbeak (Ravine).

At Glen Canyon Park, we observed a singing Bewick's Wren (above the day care center). During a brief transit through GGP we found a female N. Pintail in among the Mallards in the south channel of Stow Lake.

This afternoon during a brief visit to Crissy Field, the juv. PECTORAL SANDPIPER (found yesterday by Mark Eaton) continued along the western shore of the lagoon, loosely consorting with a couple of Killdeer. At one point, it flew off to the west with a Killdeer and appeared to set down in the "wildlife protection area" of the beach, but was back on the lagoon 20 minutes later. Also nearby was a W. Meadowlark. The only other shorebirds on the lagoon were a Willet and a Marbled Godwit.

A few repeats

fogeggs
 

A short walk on Corona Heights this morning turned up a Merlin, about 30
Vaux's Swifts, and a Black-throated Gray Warbler. During a midday hour on
Twin Peaks, I found only a few very distant raptors heading south over the
Mission District, a couple of Sharpies over Sutro Forest, and a flock of 35
Greater White-fronted Geese that flew in from the NE, over the city, and
apparently out to sea.

GGP Clay-colored Sparrow

Kevin Liberg
 

At about 9:00 this morning I saw what I believe was a Clay-colored Sparrow, by the maintenance area just west of the Bercut corral. I was struck by the bold buffy superciliam, and the unmarked gray nape. I did not see the rump. Shortly after the bird flushed, I saw the female-type Summer Tanager described by Brian Fitch in the same area.

Rob Cullison showed up but we were unable to re-find either bird. A Lincoln Sparrow then popped up in the maintenance area just as we were talking about seeing them there in previous years. We circled back about an hour later but it was pretty quiet by then.

Earlier, I saw 2 foxes at Middle Lake.

Rose-breasted Grosbeak, etc.

Dan Murphy
 

A first fall Rose-breasted Grosbeak was eating berries at the NW corner of North Lake In GGP this morning.  Also at North Lake was a Hairy Woodpecker in the woodlot across the street from the grosbeak and another at the SW end of the lake.  There were a few other common migrants.  Middle Lake was quite dead, with only a few common migrants and a Belted Kingfisher.  Stow Lake featured a female Pintail and 2 Band-tailed Pigeons.

Good birding,
Dan Murphy

Summer Tanager continues

Mark Eaton
 

The adult male SUMMER TANAGER continues at the west end sex club, a.k.a the hedges between the soccer fields and the maintenance yard. The bird was quite shy and you needed to climb the little ridge between the pedestrian pathway along the Great Highway and the maintenance yard, right in the middle of the club, shall we say.

Lewis's Woodpeckers etc.

Alan Hopkins
 

There were two Lewis's Woodpeckers flying over the Simonds Loop Area in the Presidio, I don't think they stopped. I also saw a Robin-sized black bird with a white rump land in a eucalyptus near the Letterman Center. I did not notice any white in the wing. There was also a fly-by Western Kingbird and a small flock of Vaux's Swifts.

This morning at Lake Merced there was a single male Wood Duck on the enclosure and a Tennessee Warbler at MH2.

Mark Eaton and I scoped Battery Godfry but few birds crossed in the hour we were watching.

Luke Cole Challenge - Marin to SF

Eddie Bartley
 

From a rather hot Hawk Hill perch Noreen and I watched a few uncommon
species travel into SF air space and eventually to SF land over a couple of
hours yesterday. About 20 - 30 BLACK SWIFTS continued on mixed in with many
hundreds of Vaux's. Followed one OSPREY over the gate along with many
accipiters and Red-tails. Picked up on a MERLIN coming from Mt. Tam as it
flew at break neck speed over Alcatraz then hit land at Aquatic Park
flapping like mad the whole time. Several large flocks of Band-tails made
the passage. A PEREGRINE FALCON perched on the north tower. The only other
uncommon birds were several BROAD-WINGED HAWKS none of which were witnessed
by us to make the crossing. We spent a couple of hours on the slopes of Mt.
Tam trying for Spotted Owl but dipped on that.

Don't know whether that helps the SF list for the challenge or not but this
was our two cents.

Happy Trails!

Round-up highlights East GGP 9/26/09 - Sabine's Gull, Black-chinned Hummingbird

Dominik Mosur
 

This morning I teamed with Andrew Rush and Pat McCulloch, birding Buena Vista and East Golden Gate Park.

The highlight of our day came around 9:30 a.m. when we saw a first year SABINE'S GULL land on the lake near the island in the northeast corner of Stow Lake. Having only seen this bird before on a pelagic trip out of Monterey it was quite a treat for me and Andrew and a life bird for Pat. The Sabine's Gull appeared to linger for only a few minutes, taking a drink and then flying off.

A couple of hours later, while birding the John Muir pond in the west end of the Strybing Arboretum, Andrew and I both got on a small, green-backed, female/immature type hummingbird that showed some of the field marks of a BLACK-CHINNED HUMMINGBIRD.

This hummingbird appeared smaller and slimmer than an Anna's, with cleaner/paler gray underparts that contrasted more with the upperparts than on an adult Anna's. What really got our attention, and eliminated the possibility of a newly hatched Anna's Hummingbird (which was my initial thought) was the long, down-curved appearing bill.

Also at the John Muir pond we had great extended looks at a CHIPPING SPARROW, when it wasn't being chased around by an aggresive Dark-eyed Junco.

Other notables for us included: fly-over ELEGANT TERNS (2) on Strawberry hill (furthest "inland" that I've ever noted this speceis), my F-O-F FOX SPARROWS at the Rhonodendron dell, and CALIFORNIA QUAIL (3m 4f) working the east edge of the lawn backing Rhonodendron Dell on the Cal Academy Side.

Earlier, Buenav Vista Park gave us our only BLACK-THROATED GRAY WARLBER of the day.

This evening, near dusk, I also observed (2) basic plumage FORSTER'S TERNS foraging at South Lake Merced. I think we may have missed this species earlier.

Good birding,
Dominik Mosur

The annual San Francisco Rare Bird Round Up combined this year with the Luke Cole Challenge proved to be very successful in spite of the weather.

Highlights in no particular order:

Sabines Gull - Stowe Lake, GGP
Two reports of Black Chinned Hummingbird, one at the John Muir pond in the arboretum and one from Telegraph Hill.
Two Blackpoll Warblers - One at Mount Davidson, one at the Community Garden in the Presidio
Pectoral Sandpiper - Crissy Lagoon
Orchard Oriole - Fort Mason Community Garden
Two Summer Tanagers ( as per Brian's earlier email) in GGP

From Hawk Hill we heard of Broad-winged Hawks and many Black Swifts heading into SF.

In addition there were a number of uncommon/FOS birds including Shoveler, Wigeon, Pintail etc.

We will post a full list as soon as we have it together.

Thanks to all who participated and those who found these great birds.
The Luke Cole Challenge continues through tomorrow so keep posting those sightings.

Summer Tanagers

fogeggs
 

The Western Golden Gate Park team of Robert Garriock, Bob Toleno, Juli
Chamberlain and myself turned up two Summer Tanagers this morning. The first
bird was an adult male that flew into the hedge that separates the soccer
fields at the far west end of the park from the large maintenance yard near the
south windmill. It sat out in the open for about a minute before flying
across the yard and into trees nearer the windmill, where we didn't refind
it.

The second bird was flycatching in pines near the compost pile of the
maintenance area just west of the Bercut corral, which is west of Middle Lake
across Chain of Lakes Drive. It was yellow-brown, with a red tail and vent,
and judging from our field guides, was likely an adult female, though the
limited descriptions didn't rule out a first year male.

Other birds of interest included a FOS female American Wigeon at North
Lake, two adult Cooper's Hawks perched by Middle Lake and the Buffalo Paddock,
Western Wood-Pewee, Say's Phoebe, and Lincoln's Sparrow by the soccer fields,
and a Marsh Wren at North Lake.

San Francisco Rare Bird Round Up/ Luke Cole Challenge

h cotter
 

All,
As you know tomorrow we are doing the annual San Francisco Rare Bird Round up .
This year it is also part of the Luke Cole Challenge.
We are therefore trying to compile a list of all species seen in San Francisco tomorrow and Sunday as much as finding rare birds.
If you do see something interesting or even semi-unusual please post it to sfbirds- it would be great to add it to the list if we have not seen it.
Thanks

Eastern Kingbird

angie geiger
 

Stopped by the Fort Mason Community Garden after work. At 5 p.m. there was an Eastern Kingbird at the top of one of the bare trees in the NE corner of the garden. After a few seconds it flew west into the Eucs on the opposite side of the garden, directly into the sun. I failed to relocate it, but hope it sticks around long enough to be counted tomorrow.

Good luck to all the rare bird rounders-up!

Cassin's Finch, Ibis, N. Waterthrush et al., 09/25/09

Paul Saraceni
 

With low expectations, due to the continued fog and west winds, Hugh Cotter and I birded the west side of the City this morning with some very interesting observations, just in time for tomorrow's SF Rare Bird Round-Up.


Around 9 AM, Hugh found a NORTHERN WATERTHRUSH on the northeast end of the concrete bridge at s. L. Merced. It provided us with brief views and called several times from the willows along the lake edge below the bridge.


We crossed the street to the Vista Grande Canal, and around 9:30 we located a very interesting immature oriole in the flowering euc across the "canal" from the "MH2" sign. It was chattering softly and during our brief observation we noted that it was rusty orange (not yellow) on the face and breast with a whitish belly, and had a bold, white upper wing bar that contrasted with its dark wing. Our looks at its face were too brief but it did not appear to have a dark eyeline. Based on what we observed I think it was a good candidate for an imm. BALTIMORE ORIOLE, but would have liked to have studied it more. It flew east across the street into the dense willows on the west side of s. L. Merced, in the vicinity of a boulder-filled drainage basin. It chattered a fair amount and we saw it fly a couple of times from one willow patch to another during the next 15 minutes or so, but we were unable to re-locate it perched. Listen and keep an eye out for this bird if you are in the vicinity.


At 10:45 we observed an f./imm. CASSIN'S FINCH on the west side of North Lake in GG Park, at about the mid-point of the western shore. We were alerted to its presence by its repeated "chee-up" call and located it near the top of a willow. It had a long (for a finch), straight-edged bill, rather fine, streaking below like a Siskin, and a deeply-notched tail. After a few minutes it flew off to the north, appearing to head out of the park.


Around 11:00 I looked up from where I was standing near the south end of North Lake and was very lucky to see a Plegadis IBIS sp. (presumably White-faced Ibis) flying overhead high above the treetops and heading east and out of view.


Finally, at 11:45 we observed the continuing LARK SPARROW perched above El Polin Spring. It flew east and landed in the bramble above the restoration area.


Fairly good numbers of typical western migrants (Yellow & Townsend's Warblers, Pac.-slope Flycatchers, W. Tanagers) plus a couple of migrating hawks (1 Cooper's, 1 Sharp-shin.) were around as well.


Other observations of local interest:


GREEN-WINGED TEAL 1 f. -- n. of concrete bridge, s. L. Merced
N. SHOVELER 1 f./imm. -- s. end of N. Lake, GGP
Green Heron 1 -- concrete bridge
Common Loon 1 -- off s. end of Great Hwy
Red-thr. Loon 3 -- " " " "
Eared Grebe 8 -- n. of concrete bridge
AM. AVOCET 5 -- surprising to see a small flock circling over s. L. Merced before continuing north
Eur. Collared-Dove 2 -- Vista Grande Canal
Vaux's Swift 4 -- over N. Lake
Warbling Vireo 1 -- El Polin
W. Wood Pewee 1 -- N. Lake
Com. Yellowthroat 6-8 @ concrete bridge, 1 @ N. Lake


Butterflies: Monarch, Red Admiral, Cabbage White
Dragonflies: Pacific Forktail, Com. Green Darner, Blue-eyed Darner

Orchard Oriole Dusky Flycatcher

Alan Hopkins <ash@...>
 

This morning there was an Orchard Oriole in the Presidio along with a Dusky Flycatcher.

The Birds were seen from the upper part of Simonds Loop looking down the hill near the intersection of Rawls St. This is a residential area, please respect the rights of the people who live there. The Oriole was in a berry bush, the flycatcher was along the cobblestone path that runs down the hill.

Crissy Lagoon had 1 Dunlin, 2 Least Sandpipers, 2 Willets, 1 Marbled Godwit, the Long-billed Curlew. There was a fly-by Greater Scaup and a Coopers Hawk was strafing the blackbirds and Killdeer.

FW: San Mateo Co. Christmas Bird Counts - Save the Date!

Kris Olson <kristenolson@...>
 

Hi all,



If you are looking for some variety to spice up your Christmas Bird Counts
or your year lists, here is the place to do it! We have great variety and
relatively few birders-so it's a chance to see a lot of species in some
interesting territory. Join us! Please let Leslie Flint know if you are
interested (her email is below).



Last year (or this year, in fact - Jan. 3, 2009), the Ano Nuevo count had a
Prairie Warbler and Brown Thrasher - plus roughly 175 other species. The
year before it had a Hooded Warbler that was later seen by many.



Mark your calendar and sign up with Leslie Flint if interested. We'd love to
have you join one or both of these great counts!



Kris

Hi all,

The osprey seems to have returned to its winter perch in the Burlingame
Lagoon off Hwy 101 so that must mean the Annual Christmas Count is not far
away. Sequoia Audubon invites you to join us for either or both of our
Christmas Counts:

Crystal Springs - December 19, 2009
Ano Nuevo - January 2, 2010

Please note the Crystal Springs count is one of the top ten counts in the
country - last year we tallied 194 species and tied with Moss Landing for
9th place.

The more people we have, the more area we can cover and the more birds we
will see! So, if you are interested in joining a team, please email me at
lflint@earthlink.net <mailto:lflint%40earthlink.net> .
