Mt. Diablo Audubon trip to Frank's Dump August 5

rosita94598
 

For a glorious end to another day in the paradise, 18 participants made a late walk to Frank's Dump at Hayward Regional Shoreline and were not disappointed.  Shorebirds were thick, concentrated by the high tide which pushed them off the edge of the bay.  Willets, Marbled Godwits Western Sandpipers and Black-bellied Plovers predominated, but we also had lots of Red Knots, plenty of California Gulls, a few Short-billed Dowitchers and three Red-necked Phalaropes.  A single Ruddy Turnstone was seen by some, 2 Caspian Terns and single Western and Ring-billed Gulls were also present. But a big surprise was 4 Black Skimmers flying north over the bay as we were walking back to the cars.  With other birds seen while walking, our list finished at 38 species for the evening.

Warbling Vireo

An unusual (possibly a first) for me yard bird showed up yesterday, a warbling vireo. It bathed similar to a hummingbird- skimming across the water. Later it stuck around and was foraging in it's usual manner in my neighbor's alder tree.

Odd Cal Towhee query

judisierra
 

I had a Calif. Towhee in my yard yesterday with what at first looked like a black eye. On closer inspection it looks like most of the right side of the face was dark gray and that the feathers were missing. There was a distinct edge and depth difference along the edge with normal feathers. I ruled out wet feathers, and melaninistic spot. Anybody have ideas of what caused this?

Re: Unusual Raptor Sighting at Albany Bulb

Ken Copen
 

Hi Annie, that is from my perspective, an adult Peregrine Falcon
Dark hood, dark wings, yellow cere with a darker bill tip. The only part that is a little unusual is the barring on the chest is very light. I have seen that, I took a pic of one in Moss Landing that had almost indistinct barring like this one, it could also be the lighting to some extent as well.

I would like to ask for your help in identifying a raptor photographed this
morning at Albany Bulb during a bird walk by the East Bay Nature group. It
was perched on one of the tall towers across the water from the
"sculptures" area of the park. The photos were shot from a distance but
hopefully can provide enough detail to identify the bird.

By all accounts it looks like a Short-tailed Hawk. I know how very unlikely
this is. In flight it was extremely aerodynamic and flew more like a falcon
than a hawk. Thank you for any help that you can provide.

I have posted 3 pictures at the following link:

Golden Plover at HRS, Frank's Dump

Eddie Bartley
 

The Cal Academy/GGAS Master Birding class had some very nice shorebirds this afternoon at Frank's Dump in the HRS.

An adult GOLDEN PLOVER was spotted mixed in with a large group of Red Knots and Black-bellied Plovers. Almost certainly a Pacific but it was in mid-molt and we never got definitive views of primaries, etc. Will add documentary photos soon.

By the time we arrived to Frank's Dump shorebirds were packed on the sandbars making counting difficult but numbers appeared to be up on many of the species compared to recent eBird lists in any case. Both Turnstones were about as well as at least one Surfbird. We had at least 90 Red Knots (!), 400+ Western Sandpipers, 300+ Marbled Godwits, 150+ Willets. etc. While never numerous 8+ Snowy Plovers seemed better than what I remember at this site. One tern deserving another there were at least 6 Least, 4 Caspian Terns. Great fun!

Happy Trails!

Golden eagle at Valle Vista

Wendy Parfrey
 

A juvenile golden eagle is just now catching a thermal over Valle Vista parking lot while being harrassed by a RTHA (which looks tiny in comparison). Lots of white on base of tail and primaries. Beautiful bird.


Golden Eagle flies over Hercules again

We were having lunch outside and heard angry Red-tailed calls. I thought something was chasing it but they (2 red-tailed hawks) were the ones chasing a golden eagle. The video is shaky but you will be able to see the golden eagle dropping heavy artillery on the red-tailed escorting it out towards Crockett Hills where it belongs.

Common Tern Ballena Bay

Patricia Bacchetti
 

Today at 1 PM, just after high tide, Judith Dunham and I saw an adult Common Tern on the breakwater along with 2 Least and 4 Elegant Terns. There were a few Black Turnstones and Black Oystercatchers, as well as a Spotted Sandpiper, on the breakwater.

https://ebird.org/view/checklist/S58527308

According to a resident, we missed the big Elegant Tern fly-out at Elsie Roemer by a couple of hours this morning. There were a few terns present when we were there at 11:45, but no where near the numbers in recent reports. The early bird gets the terns!

Reservoir project in Del Puerto Canyon

John Harris
 

Hi all,

As many of you may know from newspaper articles and other sources, there is
a proposal to develop a reservoir in lower Del Puerto Canyon. The project
is in a scoping phase, i.e. they are asking for input as to what issues
should be considered in an Environmental Impact Report. They have
acknowledged potential impacts on wildlife and other issues, but have not
really addressed the issue of recreational use of the canyon. Those issues
could include such things as the location of the replacement for the
existing road (should it be near the reservoir, should it include pullouts
for viewing, etc.), any mitigation for lost habitats, and so on. The
potential issues are identified in an initial study, a summary of which can
be viewed at this website, note there is also a timeline suggesting a
comment period for the EIR this fall:

https://www.delpuertocanyonreservoir.com/

There is also a link to a timeline. Please note that comments for the
scoping phase are due *THIS MONDAY, JULY 29*. Comments should be sent to

Comments can be sent to:

Del Puerto Water District

Attn: Anthea Hansen

17840 Ward Ave./P.O. Box 1596

Patterson, CA 95363



Or email: ahansen@...

I’m sorry for the very late notice about this, and I hope this is
appropriate for the East Bay list serve, I know lots of folks bird the
canyon, especially in the spring,

Has anyone seen the Bar-tailed Godwit today? I've been wanting to chase but tomorrow is the first day I could get away.

Elegant extravaganza - picture

With a heads-up from Judi Sierra I went to Elsie Roemer this afternoon to see the amazing gathering of Elegant Terns. Here is a photo of them flying as a cloud to land on another beach.

Elegant Extravaganza

judisierra
 

This morning at high tide there were 400-500 elegant terns at Elsie Roemer Bird Sanctuary in Alameda. Another group of 200 co-mingled in air for a few minutes and flew south. Quite a sight to watch them all take to the air and then settle again. (No predators in sight.) I left at 9:30 and some were starting to move out to a sand bar further out toward Bay Farm Island.as the tide lowered and it was uncovered.

Heather Farm Park Walnut Creek

The Caspian Tern, which has been seen on and off for quite a while in the mornings as well as the evenings, has some competition.  The last few days an Osprey has been around the large, mostly natural pond.  I saw it for the first time today after hearing earlier reports from Tracy Farrington.
Because it promises to be hot the next couple of days, maybe I'll have to pretend I'm an Osprey and take a dive into the swimming pool this afternoon.

Continuing Harlequin duck McClure's beach, Pt Reyes

Alan Bade
 

Hello birders- Today we saw a female Harlequin duck on the rocks at the southern end of McClure's beach on Pt Reyes. It was just contentedly sitting on the rocks and would occasionally preen and fluff it's feathers. We also had 3 Black Oystercatchers, along with a peregrine flying overhead. The harlequin duck is a continuing bird. I'd like to thank Susana deTrapaga for letting us know about it, and the Black Oystercatchers! Ebird list here; https://ebird.org/view/checklist/S58385662

Good birding, Alan Bade

Holly,
Great outing today. FYI, after studying the photos a bit, I'm reasonably
confident we were seeing mostly Short-billed Dowitchers. Didn't notice any
obvious Long-billed in the photos.

Good evening Birders,
Quick update to let you know the Bar-tail Godwit remained today with the
large flock of Marbled Godwits, Willets, and dowitchers at the high tide
roost in Oro Lomo Marsh. The marsh is part of Hayward Regional Shoreline.
Access the spot via Winton Ave. or Grant Ave. entrance. About the same
distance either way, though Winton Ave. lets you check out Frank's Dump
along the way. Bird was first found yesterday by Bob Toleno and Juli
Chamberlin as part of an Ohlone Audubon field trip. Bob's coordinates,
37.658864, -122.157597, worked well today.

Holly Bern and I arrived on site around 4 pm, preceded by Derrick Heins
and James (last name?). A Peregrine working the area scared up most of the
flock but a small number of Godwits remained behind. Holly picked out the
bird at 4:25. We watched it preen and loaf for at least an hour. We got to
see the underwing pattern (though no photo) showing black and white
barring, indicative of Siberian race.

Also with the flock was an interesting Surfbird in breeding plumage. Not a
common sight in the Bay Area.

Juli Chamberlin and i led a field trip for Ohlone Audubon to the Frank's

standing on the Bay Trail next to Oro Loma Marsh, just a short distance

dozens of Willets and Marbled Godwits. (Jerry Ting was the first person to
spot the bird.) Our approximate coordinates when we spotted it:

37.658864, -122.157597

The bird was sleeping for most of the hour-plus that we observed it. It
showed a uniformly pale belly, much grayer overall coloration than Marbled,
no marbled pattern at all on the back or upperwings, a noticeably longer
primary projection than the other godwits, and, during the brief times that
it woke up and stretched its wings, we could see that the tail was clearly
barred. Many photos and videos were obtained.

Additionally, at Frank's Dump, we also saw good numbers of Red Knots, two
Surfbirds, a dozen Ruddy Turnstones, a handful of Black Turnstones, a
couple Sanderlings, one Dunlin, and a pair of Snowy Plovers on a side trail
attending a little puffball chick.

Good birding,
