Re: Yellow bellied sapsucker Buena Vista Park

Brian Fitch
 

My wife and I just left the sapsucker a while ago at BV Park.  We heard the bird around 1 PM in the flowering gums along the park side of the street, but saw nothing until 20 minutes later when Ken Moy arrived, and as we greeted him the bird flew out of the Manor House trees and into the big oak that cantilevers over the park side sidewalk.  It then flew over the three benches and into cypress.  This is along Buena Vista Ave East.

I've searched for this bird several times since first finding it on 11/27, so was glad to finally get better though still brief views of it.  Thanks for refinding it Rachel.

Other features:
- The black border to the throat looks fairly complete at the sides - I can't be sure if the few paler feathers I'm seeing in the black on the left side of the throat are just retained brown feathers from juvenile plumage or worrisome red feathers. 
- There is a small white patch at the chin in one of these photos which is maybe a bit worrisome (female Red-naped can, I think, show that)

Hi all,
Ken Moy and I had a WTSP (tan-striped) on our way in to El Polin from the Arguello gate yesterday as well.

Hi all -

There has been a WTSP wintering with other crowns along "Mount Lane" 
staircase below Rocky Outcrop; map and photos here:
https://ebird.org/checklist/S77160754
I heard it this morning, a richer more melodious "chink" than the 
local Zonotrichia. It has been feeding in the berried Cotoneaster and 
Echium seed heads about half way down.

Since it wasn't eBird flagged I haven't reported it but Hugh C 
thought some might be interested since there have been few around 
this year. Also for the SF XBC.

Cheers, Peter

Re: White-fronted Goose et al at Letterman - Oops!

Richard Bradus
 

Sorry everyone -
I messed up on the photos.

The "gang of four" was together initially (White-fronted and three Cackling), but I didn't think to take out my phone to get any photos until later. I got the GWFG by itself OK, but then a man came by to feed the ducks and the geese scattered - and I did not pay close enough attention to what I was photographing (can't see a damn thing on my phone's screen in the sun). Those are some Canadas grazing and that is clearly a Canada exiting the pond - oops.

A good lesson to actually look at my images before posting. Oh well...

Still a nice spot to re-visit.

Keeping it real,

Hi all

On a pre-lunch walkabout I headed down through the Presidio and explored the Letterman Digital Arts Complex, with its artificial stream and pond (quite a hit with the young kids, who revel in feeding the ducks and splashing about if they are allowed). I was surprised to also find a Greater White-fronted Goose and three Cackling Geese, all happily grazing on the lawn above the pond as people in the area sat eating their lunches and such. Probably the same gang that have been at Crissy Field for some time - seems that they explore nearby pastures as well.

Not much than mallards on the pond aside from a couple of full size Canada Geese, but the surrounding trees held many smaller birds (warblers, nuthatches, kinglets, a couple of woodpeckers) and there was a reasonable group of sparrows. While it can be full of frolicking kids and sometimes overwhelming number of crows, the relative absence of dogs and the range of habitats in a small area make this spot worth checking out more often. Maybe even a decent spot for fall migrants?

I managed to get a couple of lousy phone photos of the geese:

2020 San Francisco Christmas Bird Count

David Assmann
 

Even though Golden Gate Audubon is not able to sponsor this year's San Francisco Christmas Bird Count, we are proceeding with a modified count on December 29th, subject to COVID restrictions in effect in each location as of that date, and the results will be submitted to National Audubon for their CBC database.  

This has been extraordinary year, and we would like to collect any data to that might document effects of decreased human activity during breeding season, extensive fires in the west and the current drought.  With many counts cancelled, each count that can go forward is that much more important.

Because of COVID restrictions, all counting will be restricted to single households per location. As a result, we are only able to accommodate experienced birders in the field this year, though we invite people to participate in yard/feeder watches regardless of experience level.  We have leaders for each of the 17 areas, who will co-ordinate where people will count within their areas. 

If you are an experienced birder and would like to participate, please reply to sfcbcount@... (sfcbcount at gmail) with your name, email, brief birding background, cell phone number, area preference (from the list below) and include the following statement: I understand that the 2020 San Francisco Christmas Bird Count is unaffiliated and unsponsored and that each individual who participates does so of his or her own accord. I understand and accept the possible risks of participating in this count and willingly undertake it.

1 Downtown, 2 Northern Waterfront, 3 Presidio, 4 Land's End, 5 Eastern GG Park, 6 Western GG Park, 7 Sunset, 8 Twin Peaks, BVP, 9 South of Market, 10 Bayview/Hunters Pt, 11 McLaren Park, 12 Southern Waterfront, 13 Lake Merced, 14 San Bruno Mtn, 15 Crystal Springs, 16 Pacifica, 17 Colma

If you ever wanted to know about gull ages....

Alvaro Jaramillo
 

Hello all,

  I just posted this video today which summarizes photos I have of many known age (banded) Western Gulls, in order to understand how they change as they age. It is long, but you can fast forward to the ages you are interested in, as the photos go from youngest to oldest. It is unusual to actually have known details, rather than guesswork, when considering gulls. This is from years of collecting these photos, I am so glad I finally put it together! Yes, I have more, and I could have made it longer 😊. Share with anyone or any group who may be interested in this type of stuff.

Nearly all white large gull near China Beach today

Joel Perlstein
 

Perched on a rocky cliff just west of China Beach around 4 pm today.  Looked longer and chunkier than a nearby Western Gull. Plumage all white except for some light  grayish markings on the head. Legs pink, eyes dark, bill light colored with some black near the tip. Could this be an albino/leucistic Western Gull?
