Demise of ‘Frank’s Dump’ as a shorebird roost

Noah Arthur
 

Sadly, it looks like the East Bay’s flagship shorebirding destination is no more. On my first targeted shorebird outing of the season this evening, I found Frank’s Dump at Hayward Shoreline to be mostly dry with almost no birds, even during a very high tide. The small channel of water that used to trickle in to the northwest corner of the area at high tides was completely dry, apparently blocked somewhere under the levee. 

Unfortunately, the loss of this location also probably means the end of East Bay shorebird migration as we knew it everywhere else too. I don’t know of any other major shorebird high-tide roost sites in the East Bay, and Frank’s was probably where the vast majority our shorebirds roosted. The big foraging flocks from as far as Alameda South Shore apparently roosted at Frank’s — at least, we know the 2017 Red-necked Stint shuttled between those two locations. Without Frank’s Dump as a roost site, I believe most of the migrant shorebirds we used to see will simply no longer stage in the East Bay on their way south.

Failure of Forsters Tern Colony Hayward Marsh

Jim Chiropolos
 

In the summer one of the high points of Alameda county birding was enjoying the breeding tern colony by the Hayward interpretive center by the San Mateo bridge. In past years in this area, a constant stream of Forsters and Least Terns would be crossing to the bay calling and bringing fish back to the colony. Unfortunately, the Forsters colony, in previous years maybe 200 terns or more in size has apparently failed. In three visits, I have not seen a single Forsters. The Least Tern colony is present but seems reduced in numbers. Sad.

Questions
1. Does anyone know why this failure has occurred- it may be the only breeding Forsters tern site in the east bay.
2.Did the terns relocate to new location maybe across the bay?
3. What can Hayward Marsh do to reattract Forsters Terns to this site next year?
4. Is the Least Tern colony less viable without the Forsters? Ravens and Harriers are patrolling this area. (Are ravens more common on the bay now - I think so)
5. Who is monitoring this colony? Can you contact me.

Hopefully- there are steps we can do to help this colony breeding location next year.

Finally, shorebirds are returning.

Lewis’s Woodpecker and Western Tanager

Johan Langewis
 

The Lewis’s Woodpecker continued today at the same location at Valle Vista, seen by a number of birders, as well as non-birders that got a peek through my scope. It moved from one location to another, but not so far to disappear from view (most of the time), remaining at each location long enough to get a good view. After that I continued south along the trail about 50 yards and saw a bright male Western Tanager fly to a pine tree, perch for about 30 seconds, then fly off to the west. eBird didn’t like that sighting, but I’ve seen Western Tanagers here in June in years past.

I forgot to mention, for anyone not familiar with Valle Vista, that it is EBMUD property and a permit from EBMUD (available online and good for all of EBMUD's public trails) is required to enter. You may purchase a permit here:

Lewis's Woodpecker continues at Valle Vista

Lee Friedman
 

Thanks to Bill Cone and Johan Langweis for finding and calling attention to the Lewis' Woodpecker at Valle Vista last week. This note is to report that as of yesterday it was still there, sticking pretty closely to the snags and poles by the horse corral. If you haven't seen it, this bird is a beauty and there is a good chance that you will be successful in finding it on these open perches.
 
A photo of it from yesterday is here:
 
 
In addition, Valle Vista has not heard about any summer doldrums. There was also a Lawrence's Goldfinch, Wood Duck at the edge of the shrinking water in the reservoir, a Pine Siskin that didn't get the memo about migrating elsewhere, and numerous other nice birds. A photo of the Lawrence's Goldfinch is here:
 
 
My eBird list of 33 species with a few additional photographs attached is here:
 
Good birding,
Lee Friedman


Finally a bird to photograph

Claude Lyneis
 

I was out on the Wild Cat Trail about .9 mi north from the Little Farm today and there was a nest with three raptor chicks.  It was hard to get a clean shot with all there branches, but the chicks were quite big and active.  
Once home and looking at the photos, I am quite sure that they are Cooper’s Hawks.  I have on a few occasions seen a Cooper’s Hawk out there.

Here is a link to one of the photos and it looks like ones in iBird.



Cloud seeding and bird migration?

Noah Arthur
 

Has there been any research on the impacts of cloud seeding on migratory birds?
Silver iodide cloud seeding has been done in the U.S. West for decades, but has increased in 2020-21 due to extreme drought conditions and recent studies showing that it does actually work. Mexico is also seeding clouds with *acetone* this year. Coincidentally -- or not -- spring migration in the West this year has been extremely unusual. Migrants and breeders are simply not arriving in normal numbers in many areas, while many winter birds are leaving late or not at all. Eastern vagrants are also nearly absent from our coast this spring. The drought itself has been blamed for these unprecedented changes; however, I'm skeptical of this theory. Breeding birds aren't just failing to breed -- many are not arriving on the breeding grounds at all, especially in the interior West. I don't think drought conditions on the ground would would stop birds traveling high in the air from getting to where they should go. So I suspect the culprit may be something happening up in the atmosphere.

I wonder if the increase in cloud seeding is responsible for the unprecedented changes in bird migration we're seeing in the West this spring. Could it be that birds are not migrating as far as they normally would, because they can't or won't fly through plumes of silver iodide and acetone in the atmosphere?


And another discussing cloud seeding in Mexico:

Re: Hawk at Kaiser Hospital atrium

Cathy Bleier
 

On behalf of Craig Nikitas, Chief Operator, Bay Raptor Rescue:
“The hawk that was captured at Kaiser Medical Center was taken by us (Bay Raptor Rescue), although an Oakland Animal Services officer was present. That bird is a 2020 hatch, and is almost certainly not part of the territorial pair familiar to many folks in the area. The paired birds probably show adult plumage. During the time the 2nd year bird was in the hospital atrium, two observers later reported seeing the pair of adult birds overhead.
The captured bird was in the atrium for several hours. It was unable to generate enough lift to get out of the multi-story atrium. A field exam showed the hawk was not notably underweight nor dehydrated, and it displayed no obvious injuries or plumage deficiencies. Also the crop was not distended, and thus its inability to escape the atrium was not attributable to overeating, so therefore we drove it to WildCare in San Rafael for a diagnosis and treatment. Subsequent radiographs and blood work were both normal. Joint motions were all normal. It’s not obvious yet why it can’t fly properly. The hawk was prescribed pain meds and cage rest, to see how it responds. My hypothesis is that it was attacked by one or both of the two territorial birds to drive it off, and suffered bruising or other soft tissue injury, and went down into the atrium to escape. “

Lewis’s Woodpecker

Johan Langewis
 

I relocated the Lewis’s Woodpecker found by Bill Cone at Valle Vista on Sunday June 20. I saw it on top of a phone pole near the horse corral on the Rocky Ridge Trail this morning at about 9:30 AM, 37.8183 Lat, -122.1325 Long. Last time I saw one here was about 25 years ago.

Partial leucistic junco

Stephen T Bird
 

An hour needed occupying on the Cal campus, so borrowed a pair of lab nocs and set out. Found a nice partial leucistic oregon dark eyed junco behind Moffit library (north side).
Interestingly, the face markings had near bilateral symmetry. There are likely those among the list serve that will know better than I, but my first thought was that  this would suggest a somewhat-late somatic neural crest mutation. Would enjoy any speculation.

Otherwise either highly unremarkable if looking/listening for unique vagrants or high species counts; or remarkable for sussing out the slow beauty of a place and the movements of species across continents.

Best,

Tilden - Grasshopper & Lark Sparrows, Macgillivray's Warbler & Others

Zac Denning
 

On my weekly birding by ear trail run in Tilden this morning, it was frigid densely fogged in, and extremely blustery on the slopes and ridge. Starting near the Little Farm area, going North on the Wildcat Trail, then turning up the Conlon Trail, there was a Grasshopper Sparrow singing closer to the bottom of the hill this time. They seem to like to sing when the weather is miserable. I also heard an Ash-throated Flycatcher calling, both at the bottom and then later at top of the ridge. There are a few of these in Tilden, but not many. Not far from the Ash-throated, at the top of the Conlon trail, about 1/4 mile from the junction with Nimitz Way, there was a Lark Sparrow singing quite near the trail. And the MacGillivray's warbler was singing from it's new usual spot, 50-75 yards North of the Albany Berkeley Kensington Hikers Club Tree Grove, along Nimitz Way. 

Turning down the Meadow Canyon trail, there was a blue-gray gnatcatcher calling, and several California Thrashers singing faintly above and below the trail about 1/2 mile from the parking area. 

All in all, it wasn't bad audio birding for a foggy, windy day with little to see. Ebird list with audio recordings of the sparrow, as well as locations are included below.

Happy Birding,

Zac Denning

Re: Hawk at Kaiser Hospital atrium

Charlie Wells
 

Can you tell me which Kaiser this is?  There is a pair that likes to hang out on the Southwest corner of the Kaiser on Piedmont and MacArthur that I have been watching for a while.  Why would animal control be trying to capture this one?

American Redstart at Creekside Park Albany

Sam Zuckerman
 

AMRE female singing at Creekside Park, Albany side, on hillside south of trail between Madison Street and Cerrito Creek crossing late Sat. morning. Moved back and forth from near trail to further up hillside near trail going up Albany Hill. Alerted by unfamiliar high pitched song that first sounded like Brown Creeper, but quickly identified as unrecognized warbler. Eventually sighted repeatedly, showing grey head, offwhite belly and yellow patches on side and tail. Vocalization recording and photos at https://ebird.org/checklist/S90447075.

Bay Raptor Rescue (https://www.bayraptorrescue.org/) is one such org that rescues hawks trapped in buildings. Sounds like someone, maybe them, is already on the case. If it's a bird that has eaten recently, it might take some time for it to go for the bait.

Hi Jen,

I’m sorry but EBB does not allow for photo attachments, by popular consensus (to reduce the size of group emails). If you want to share a photo, you need to put it on a photo sharing site such as Flickr or eBird and then provide a link to it. Thanks for understanding,

Zeiss

Steve Taylor
 

This is not the purpose of this web site so I apologize to all in advance.

Recently my pair of Zeiss 8x25 Victory binoculars broke. A little wheel part broke off for unknown reasons. I sent them back to the Zeiss repair facility in Kansas. They emailed me when they received them. They emailed me after they inspected them and they emailed me asking if I wanted my old pair back. I said no.

Today I received a brand new pair, case and all shipped overnight at no charge. That’s what you call outstanding customer service and standing behind their warranty.

Keep this in mind next time you are looking to upgrade or purchase a new pair of binoculars or a scope.

Nothing exciting bird wise, we seem to be starting the summer doldrums early here.  Song Sparrows were singing, I heard a Nuttall's Woodpecker, Scrub Jay and Bushtits.  The Muscovy Duck was hanging with the Canada Geese on the lawn near the concrete pond, seven ducklings are left from the family of nine first seen on Sunday in the mostly natural pond.  No Red-shouldered Hawk today, but a Red-tailed Hawk was seen on a power pole.
