Juvenile peeps are super variable in how bright they are. This is independent of wear, same day, same place and you photograph let's say 20 Least juveniles and you will find a ton of variation. Same goes for Western etc.

It's a unanimous opinion that this is a juvenile Least Sandpiper. Many thanks to Alvaro, Joachim, Fred, Joe, and Dominik for commenting on it.

Though I accept the fact that I should concentrate more on the structure of this sandpiper that will help me to identify it correctly, I am still bothered by its plumage.
It's just late July now so shouldn't a juvenile Least Sandpiper (which should be among the earliest arrivals) possess a much brighter plumage than the bird I photographed? I compared all juvenile Least Sandpiper photos I took for the past 10 years and also browsed through images of juvenile Least Sandpiper in eBird Macaulay Library (using the filter juvenile/immature during July and August for all years) and notice they all have much brighter overall color with wider tawny edges and darker-centered feathers on lesser and median coverts.
The sandpiper that I photographed has grayish lesser and median coverts and almost no dark on the center of feathers.

Then I used the same filters (juvenile/immature during July) to search for Western Sandpiper in Macaulay Library and found these: https://ebird.org/media/catalog?bmo=7&taxonCode=wessan&mr=MCUSTOM&emo=7&q=Western%20Sandpiper%20-%20Calidris%20mauri&age=j
Much better match of the plumage with the sandpiper I photographed in my opinion and structure-wise is also quite similar.

I have even thought about the possibility of hybridization but couldn't find any documentation online about Least/Western or Least/Semipalmated Sandpiper Hybrid. By the way, Google 'calidris hybrid' and you will find some cool articles.

I will settle this bird as a juvenile Least Sandpiper as suggested for now and keep looking for the interesting ones to raise my, and hopefully yours too, curiosity.

Stay Safe and Happy Birding,

Oakland hills migration

The first hermit warbler of the fall moved through the yard Monterey pines today. Listen for their chip - they like Monterey pines....I have had several tanagers move through the yard already too, but the first hermit warbler is the big sign birds are on the move in the Oakland hills.

Hi Jerry.  Why don't you think it's a juvenile Least Sandpiper?  Your photos (and description) seem to match the photo featured on eBird, which is also here: https://www.allaboutbirds.org/guide/Least_Sandpiper/media-browser/64822671

Peregrine Falcon at Albany Mudflats State Marine Park, Albany, Alameda CA

Don Simonson
 

A Peregrine Falcon was a thrilling sight at the Albany Mudflats, Alameda; observed at approximately 3:15 pm today 7/27, from eastern most viewing platform, on the north side of Buchanan Street. I was counting Marbled Godwits -about 105 - on the mudflat  when something dark and very fast caught the corner of my eye coursing northeast. After crossing the flats it towered up to about 500 feet, then flared its tail and wings briefly to soar before rocketing off to the south.Good birding!

Scaup and others, Contra Costa County

Ethan Monk
 

Shorebird migration has been going on for a while now, but the passerines have started moving through the past couple of days. This morning at Pt. San Pablo this was highlighted by a Warbling Vireo and a somewhat early Black-throated Gray Warbler. Rare at the point was a Lesser Yellowlegs in the Gun Club Marsh, a Pacific Wren across the street, and a likely long continuing Hairy Woodpecker at the county park. I checked Pt. Isabel for the first time since the Scaup discussion on here and found 8 scaup, about half of the summering flock: All of them were Greater Scaup. The Lessers can tend to segregate themselves out, so it is possible the 1-3 Lessers were in a place I couldn't see them from my Contra Costa vantage point.

While I'm here, some miscellaneous sightings of note:

--Last Monday a (the?) quite freshly dead Murre was beached at Vincent Park.

--Last weekend in the delta, I counted 189 staging Bank Swallows--126 of these in Contra Costa county, the rest on Sacramento's Sherman Island. Tree Swallows were present in good numbers (3-400), too, with large numbers of immatures.

--In terms of hummingbirds, the last Allen's females and immatures left a week ago, and the first Rufous arrived on the 15th in Alamo/S Walnut Creek. There seems to be a problem with this every year, but it is best to count female-type selasphorus as Rufous/Allen's unless you have conclusive photos of the tail feathers until at least half way through August. For anyone keeping track, the Costa's at my house left the 20th.

Oh, and I couldn't find the flock of Wilson's Phalaropes at Richmond Pond today. They seem to have left. Good birds for Richmond--it's a bummer they weren't noted on here.

Good birding,
Ethan


Sunday late at Frank's Dump

rosita94598
 

Today would have been the day of our Mt. Diablo Audubon Society field trip to Frank's Dump.  Due to the current pandemic, of course, we are not doing any field trips and do not know when we will.

Still, three of us walked to Frank's Dump for the late high tide, starting from the end of Winton Avenue at 4 PM.  Just as Ted Robertson, my wife, Rosita, and I arrived at Frank's Dump and were ready to clamber down below the levee to be out of the wind, we were joined by a Maryland birder who is caught here in California by the pandemic.  Don Simonson joined us and then we found Pat Mahoney who had walked out earlier.

Pat told us that the number of birds today was down from yesterday, but we did not have too much trouble finding the previously reported Pacific Golden-Plover.  Sometimes it was hidden behind the many Black-bellied Plovers, sometimes it was very well seen.  Red Knots were mixed in with them, and Least Sandpipers were behind all of them, nearly invisible.

We had seen some distant Snowy Plovers and a couple of Semi-palmated Plovers, so we ultimately walked a bit north and turned right along Sulphur Creek.  There is not much water in Frank's Dump compared to years past, and this part is always dry when we visit, but it was especially productive for Least Sandpipers, Snowy and Semi-palmated Plovers.  Rosita counted 7 baby Snowy Plovers running around. 

We had a few distant raptors, including White-tailed Kite and Red-tailed Hawk.

Don Simonson's eBird list is here:  https://ebird.org/checklist/S71859417

It has not appeared as I am writing this, but Ted Robertson's eBird list will eventually be here:  https://ebird.org/region/US-CA-001/activity?yr=all&m=

On the way out, I took advantage of the drive-up window at Jack In The Box and had an order of Seasoned Curly Fries--a great way to end the evening.  A cold drink helped them to go down.

7/26, 3:30 PM: Pacific Golden-plover continues at Hayward Shoreline, Frank’s Dump. Just flew and a few birders are hoping it rejoins the Black-bellied Plovers et al.

I don’t think they were certain on the ID yet when I got the text.  Hopefully they have some good photos and can determine the Bird to species tonight.  This was an outing of the California Young Birders, and I’m sure they’re pretty cautious on their ID’s. 

Pacific Golden-Plover is a lot more expected, and they have been annual at Franks Dump for a long time - I think one overwintered there and was last reported on eBird in April. American Golden-Plover is a lot rarer, but most of the Bay Area records are from the early fall.  So if it’s going to happen, now is a pretty good time.  Ethan or Lucas can clarify assuming they got good looks and/or photos.

Bald eagles, Grebes and Blue grosbeaks at Clifton Court Forebay

Alan Bade <alanbade@...>
 

Greetings- Today we went to Clifton Court Forebay for our first time there. We had 4 Bald Eagles on Eucalyptus island. Two adults and two juveniles were in the eucalyptus trees that are also used by Cormorants and Great Egrets. The juvenile eagles were screaming to be fed. After I process audio, I'll try to put it into our ebird list. We also had Clark's and Western Grebes, with approx 30 nesting on grassy islands out on the water. I listed these as Western/Clark's as they were pretty distant. A nice bonus were a male and a female Blue Grosbeak on our way out to Euc island. We heard the male singing in a lone willow tree and it then flew over to blackberry bushes along the levee . The willow is in between the main road and the dirt levee road about halfway out to euc island.

Acorn Woodpeckers

Kay Loughman
 

Yesterday morning I had a thrill when I saw a juvenile Acorn Woodpecker at one of our seed feeders.  First time ever.  This morning there was a different Acorn Woodpecker at the same feeder; and briefly that bird was joined by yet another on the rail while they waited for a Steller's Jay to leave the feeder. Those two were also young, though I think of somewhat different ages, and no longer juvenile (note the feather color distribution on the heads).   In the course of the next few minutes I saw at least two more of the same species in nearby trees.  Family group extending territory?  Curiously, both of the two on the rail today had bumps or some sort of crud on their upper beaks.  Possibly pox?  Or what else?

I took several pictures, at odd angles through dirty double-pane windows, and posted a few to my website.  Comments appreciated.
