Re: East Bay Passerine Migration

Alan Bade
 

Thanks Jim! Sounds like we'd better go to Vollmer Peak soon. We had two Western Tanagers in Castle Rock's Pine creek canyon over in the Mt Diablo foothills this morning. We like to stake out some of the pools along the now dry creek. It might be a little early so far. https://ebird.org/view/checklist/S59380968

So far, over the same time period, the bayside migration has been VERY SLOW with only one yellow, one yellowthroat, and one pac-slope type bird the only migrants seen at my office on the bay in Emeryville. Its interesting how migration works and some areas are oasis and other areas are very quiet.

Tilden Vollmer Peak--FOS Townsend's Warblers

Lee Friedman
 

This morning at about 9:30AM I saw at least three, perhaps as many as five, FOS Townsend's Warblers in the pines on both sides of the Seaview Trail in the Vollmer Peak area of Tilden Regional Park.

late post for Baird's Sandpiper at Middle Harbor Shoreline Tuesday

Derek
 

Laptop issues delayed my ability to download photos from a quick stop I made
at Middle Harbor Tuesday at 1pm, but when I finally got that issue fixed a
closer look led to determination of Baird's. Ebird link below with one good
photo. FYI, it was the only non-Least Sandpiper peep that I saw at that
stop.

Continuing Pectoral Sandpiper August 28

rosita94598
 

After missing each other at McNabney Marsh yesterday, Bob Dunn and I managed to arrive within minutes of each other at the West County Wastewater District facility in Richmond this morning.  We easily found the continuing Pectoral Sandpiper across the road from the office.  The gate to the ponds is a bit to the south and the bird was in the first pond through the gate.
Other birds present were Killdeer, Least Sandpiper, Greater Yellowlegs, two Red-necked Phalaropes, Barn Swallow and more.  Bob's eBird list is not yet posted, but should be available soon.  We were there between 9:30 and 10 AM today.

Contra Costa birds Tuesday August 27

rosita94598
 

We have two continuing Common Gallinules in the large, mostly natural pond in Heather Farm Park, located in the Ygnacio Valley of Walnut Creek.  An adult Pied-billed Grebe was seen again today, and Fred Safier found a male Yellow Warbler. 

Closer to noon, I visited McNabney Marsh and Waterbird Pond in Martinez.  The young Black Skimmer is still at McNabney Marsh, along with the many other expected species like White Pelicans, both Egrets, Pied-billed Grebes and Mallards.
Waterbird Pond, over the hill from Waterbird Park, had over 200 Short-billed Dowitchers.  Also seen were Black-necked Stilts, Greater Yellowlegs, Mallards, Green-winged Teal, Northern Shoveler and Gadwall.  The surprise was seeing two Red-necked Phalaropes.

Thanks for posting this Graham. For anyone interested, the pectoral
sandpiper is still present today. It's on the southern bank of the middle
of the eastern ponds. The phalaropes and many killdeer are nearby.

Happy migration,

Redwood regional park today

Philip Georgakakos
 

Hello Birders,

I walked around the Skyline gate area at Redwood Regional Park this morning for about 2 hours starting at 9:45. I parked on Skyline near the intersection with Phillip’s Loop trail, walked East Ridge Trail to Prince trail, headed down into the valley, and back up via Eucalyptus and Phillip’s loop.

There was a Hermit Warbler in the cypresses where I parked at the intersection of Phillip’s Loop and Skyline Blvd. Quite a bit of mixed species flock action in the tall pines in between East Ridge and Phillip’s loop, with 2 Western Wood-peewees and an Olive sided flycatcher amongst Pygmy Nuthatches, Red-breasted Nuthatches and Chicadees. Also spotted a yearling Western Tanager around here. Not too many warblers though. Full checklist here:
https://ebird.org/view/checklist/S59227030

Have folks started to see other passerines moving through the area?

Juve Black Tern at HaywardShoreline-Franks Dump

Srikant Char
 

Went chasing Noah's reported BAGO, but as usual the million MAGOs ended up giving me same eye-strain like in previous check. Dipped on the BAGO :)
However, i spotted this slender black & white Tern on the mudbank and quickly id'd it as a juve BLACK TERN! Black wings and black spot in front of eye, squatting on a mudbank with active WILLETs, DOWITCHERs and peeps. I watched & clicked for about 5-10mts and briefly turned my eyes down to adjust tripod and it was gone! Scanned futilely for next 20mts in vain.

Hope it resurfaces for more sightings.

(2) Red-necked Phalarope at Lake Merritt (Alameda) Fri Aug 23 at 1715

Hi bird friends,

This afternoon I observed (2) Red-necked Phalarope at Lake Merritt. eBird indicates that this is the first record of the species there. Here is the list with photos: https://ebird.org/view/checklist/S59213072

Godwit photos

Noah Arthur
 

I've added some photos of the apparent BAR-TAILED GODWIT to my eBird list... https://ebird.org/view/checklist/S59188688
I'm pretty sure now that this is a Bar-tailed and not Hudsonian or Black-tailed, due to the shaft-streaked upperparts.
Noah

Good godwit at Franks Dump

Noah Arthur
 

The unusual godwit that was reported with distant photos on Facebook yesterday, was back in Franks Dump this evening along with hundreds of Marbled and Willets. It’s definitely one of the exotic ones and looks to me like the same Bar-tailed that’s been kicking around the Bay Area the last few falls. However, I know next to nothing about distinguishing one rare godwit from another, and some people commented on the original FB post saying they thought it didn’t look like a Bar. I put it in ebird as such bUt will edit if needed...
Also present were TWO (yes two) PACIFIC GOLDEN-PLOVERS. 
Good shorebirding!

Contra Costa sightings

rosita94598
 

We have been seeing an adult and a young Common Gallinule at the mostly natural pond in Heather Farm Park.  This is in the Ygnacio Valley of Walnut Creek.  Also there for the last week or so are two Pied-billed Grebes, one of which is less than adult.  Most days there is some combination of waders, either Green Heron, Snowy Egret, Black-crowned Night-Heron or Great Blue Heron.  Up to 5 Killdeer have been seen on the ball fields across from the pond.
This afternoon at McNabney Marsh adjacent to I-680 in Martinez, the previously reported Black Skimmer was still present.  It prefers the flat, grassy island best seen from the parking lot at Waterbird Park at the northeast corner of the marsh.  A scope is helpful.
Midway south along the marsh is an Osprey platform, which was erected by Mt. View Sanitary several years ago.  Today I saw two Ospreys sitting in attendance at the platform.  This is best seen from the viewing platform along the entry road to Mt. View Sanitary at the south end of the marsh.  Also at the south end were 7 Pied-billed Grebes and 5 Killdeer.  Lots of Mallards were scattered throughout the marsh and at the north end a number of Dowitchers, Stilts and Greater Yellowlegs.
At Waterbird Pond farther east on Waterbird Way and at the entrance to Acme Landfill, I counted 54 Black-necked Stilts.  It was well over 90° when I was out there and did not realize that my tee-shirt was becoming wet with sweat until I was leaving the landfill entrance.

eBird protocol for most introduced species (with a handful of exceptions) is for reviewers to invalidate the record with the flag "introduced/exotic". This removes the records from all public output, including maps, but they are still present in the dataset and visible on the individual checklists. I've heard that the rationale for this protocol is to reduce the clutter of introduced species on bar charts, although that seems pretty trivial and I'd like to see introduced species included in public output.

If anyone is interested in analyzing records of a specific introduced species, it's relatively easy to get these invalidated records in the eBird Basic Dataset download.

Sycamore Grove Park south of Livermore. It was quite a celebrity. Did you
miss this message?

https://groups.io/g/EBB-Sightings/message/12346

But much of the discussion was on the discussion list starting at:

https://groups.io/g/EBB-Discussion/message/57

The bird was originally found by Dean LaTray on 5 April posted on eBird:

https://ebird.org/view/checklist/S54603587?view=photos

with many follow up eBird posts some containing outstanding photos. Here is
a partial list:
