Date   
Another Alta Plaza Palm Warbler

Richard Bradus
 

Another week, another surprise.

Walking up the east side of Alta Plaza Park shortly before 1 pm today I was idly following a Yellow-rump when another warbler flew in to forage in the small trees. The bobbing tail was a dead giveaway. A returning Palm Warbler? Nope, a different one! This one is considerably paler than last year's but, even without binoculars, the eye line and the bright yellow undertail coverts were quite apparent. Plus there was the almost continuous bob-bob-bob of the tail. It was quite active so it may or may not be readily re-found, but perhaps it will stick around for awhile.

BTW, for any of you Deadheads, there is a really sweet "Supplication" jam in today's 30 Days of Dead offering. Joe-Bob says check it out!

Happy trails,
Richard Bradus

Snow Geese, Harbor Porpoise

John Luther
 

Hi All,

Yesterday Nov 12 Leora Feeney and I observed from the west corner of Alameda 10 Snow Geese flying northwest towards Yerba Buena Island.  The geese were over SF county waters.  Also for the first time for Leora and I we saw from Alameda (although they were in SF county waters) 6 adult and 2 young (about half size of adults) Harbor Porpoise in the same area.

Re: Blackpoll warbler, GGP Alvord Lake

Bob Hall
 

I should add more context before I look in the book and become biased about my observation. 

—Looking from the top down, greenish-yellow appearance
—Lighter yellowish wash on the breast, light streaking where wings meet breast
—two wing bars
—Light yellow halo around the eyes
—White in tail feathers stood out during fly catching
—Cross hatching on the back

Damn impeachment testimony and biodiversity event planning had me pinned in this morning.

Good luck!

Bob,

A "Blackpoll"  would be extremely lay at this time. One going to the ground in November sounds like a possible Pine Warbler as suggested by Curtis Marantz.

Anyone in the area might want to follow up on this report.

I was passing by Alvord Lake with no bins, but the place was jumping and stopped me. Four townsends nearly collided with my chest during bug sorties. I saw a suspicious bird but couldn't nail it down. Went home and wolfed down lunch then returned with bins. Most of the warblers were gone except the slow moving blackpoll that would occasionally go to the ground. Most of the birds were hanging out in what looks like a hawthorn tree with berries near the lake.

I’ve only seen two pine warblers in my life and I’ve had trouble with them, so that’s a possibility. When I saw the cross-hatching on the back I went to blackpoll. 

I look forward to further insights.

Fort Mason Local Interest

David Assmann
 

No new rarities, but there are a couple of interesting continuing birds at Fort Mason.  The male ORCHARD ORIOLE has now almost completely changed color and was active in the garden this morning. A YELLOW-SHAFTED NORTHERN FLICKER is often in the garden and the Battery (there may be two birds), along with an intergrade NORTHERN FLICKER.  The WANDERING TATTLER was on the pier at high tide this morning. I had eight WESTERN MEADOWLARKS on the Great Meadow this morning - this has been a banner year for them at Fort Mason - I've had 111 since the third week of September - last year during the same time period I only spotted 17. 54 species total this morning.

Re: [northbaybirds] Information re: Tricolored Heron siting at Chrissy Field yesterday afternoon

Mark Stephenson
 

Hi Joe!
I corrected the time of the sighting to 4:58. The Booby returned at 4:38. Sorry for the error. I relayed this information to Courtney. I would guess the Heron could fly the mile or two fromthe  lagoon to Chrissy Firld in 5 minutes or so. It’s hard to believe there are 2 different Herons in the same vicinity. 
Cheers,
Mark & Lucas

There is a report on Facebook by Courtney Buechert who said the bird was
still at Rodeo Lagoon between 4:30 pm and 4:45 pm yesterday (Monday). So at
4:38 pm the bird was still in view at Rodeo Lagoon.

However, the time stamps on the SF photos by Lucas and Cedric posted on
eBird are 16:57 and 17:00 or 5pm which is a better fit for the same bird
theory.

FWIW, it was still at Rodeo Lagoon around noon today.

Very helpful, thanks. A few of us are at Crissy waiting for its flight. It would be a fine evening ritual!

Blackpoll warbler, GGP Alvord Lake

Bob Hall
 

I was passing by Alvord Lake with no bins, but the place was jumping and stopped me. Four townsends nearly collided with my chest during bug sorties. I saw a suspicious bird but couldn't nail it down. Went home and wolfed down lunch then returned with bins. Most of the warblers were gone except the slow moving blackpoll that would occasionally go to the ground. Most of the birds were hanging out in what looks like a hawthorn tree with berries near the lake.

R f booby

Flew in at 8:04, but I did not get to see it dive.
No tric heron, but see north bay birds for an interesting phenomenon.
There are two r f boobies in SF, but how many tric herons?

More Crossbills west SF

Josiah Clark
 

I had red crossbills again in two separate spots today in the city including about 15 at 23rd in Geary behind the grocery outlet over street. They seem to have come from a big Monterey Pine tree there. The more deep, throaty calls sounded like the local ones that used to breed in the city. Along with the red-breasted nuthatches, I have to wonder if this winter eruption of crossbills is due to a pine nut failure elsewhere in their range.
A few more Red Crossbills were in the cypress trees right by Kezar Stadium. Enjoyed a close visit from a Townsend’s warbler today in the yard but generally many fewer birds in the yard this winter for me.
Good birding

Bernal Heights Northern Goshawk.

bitanangan
 

Hi Birders,
      Took a while to process this, but I saw an adult Northern Goshawk from Alemany Farm at St Mary’s Park today c 12:50 PM. It glided N, fairly low, across highway 280 just E of the farm towards Bernal. Field marks were a large accipiter with a stunning broad white eyestripe, steel-blue (or was it steel-grey?) back and a long folded tail. Looking later at recent ebird sightings, I luckily found that Rajan Rao had already reported a large accipiter at St. Mary’s earlier this morning which then emboldened me to make this otherwise preposterous report. However, I don’t know how anyone could possibly chase this. St. Mary’s Park attracts a lot of birds, including scorned alien oddities like Scaly-breasted Munia. Thanks Rajan for your ebird report!
