Tilden Regional Park -- 9/20

Michael Park
 

After several days of birding places that were far from home, I decided to visit places much closer to home. I visited two of my favorite places there -- Inspiration Point and Jewel Lake, to look for Broad-winged Hawk and scarce migrants.

When I arrived at Inspiration Point after noon, strong winds from the west were present. As I stepped out of my vehicle, a Sharp-shinned Hawk zoomed by the lookout at the parking lot. I thought this to be auspicious. Maybe because of the strong winds, raptor activity was low.

Sharp-shinned Hawk (1)
Cooper's Hawk (3)
White-tailed Kite (1)
Red-tailed Hawk (6)
Turkey Vulture (19)

Most of the large raptors were passing over the ridge east of San Pablo Reservoir. While scoping three raptors in that direction, I noticed several much smaller, dark birds. Their flight style suggested Black Swift. After several minutes of watching them, I discovered that these were part of a larger group of at least 7 BLACK SWIFT.

At Jewel Lake, the water level was the lowest I have observed since moving here over 25 years ago. There were still a few Warbling Vireo, a Pacific-slope Flycatcher, Hutton's Vireo and Townsend's Warbler. A young Common Yellowthroat that I saw several days ago seemed to have departed. One of two Lincoln's Sparrow seen then was still present. I haven't detected Swainson's Thrush in some time, so they are gone.

Townsend's Warbler

Johan Langewis
 

The FOS Townsend’s Warbler appeared in my yard this morning. The Allen’s Hummingbirds are gone, but I still have at least 8 Anna’s, draining about 16 oz of sugar water a day out of my feeders. When the Allen’s were here there were at least 14 hummers around, drinking about 24 oz of sugar water per day. I’m used to having one or two at a time. I live in the Oakland Hills near Shepherd Canyon and Skyline Blvd.

Bluebirds North oakland

The good news is I found 3 Western Bluebirds in the east side ball fields of Bushrod Park early Sat 9/17 after trying to pin down a cacophony of bird song when it had been dark. I hadn't seen any on the Shattuck side fence in the spring when I looked. The bad news is the city is removing 7-9 sycamores which they say are dead (although they are partially leafed). I believe if they were nesting that is what they're using.

Parasitic Jaeger Emeryville Marina

Jim Chiropolos
 

On Monday at lunch at noona  chocolate colored parasitic Jaeger flashing white at the base of the primaries flew about 75 yards off the Emeryville Marina looking towards the golden gate bridge flying north.


Also on Monday a female common merganser was on the bay north of Chevy's; it was gone at noon.


The Emeryville migrant songbird trap locations held only one yellow warbler on Monday - a low count in September.


Good Birding,

Two Hermit Thrush - EBMUD-Bear Creek Staging Area

Denise Wight
 

Hi E. B. Birders,

Nothing rare to report, but it was nice to hear and see my first Hermit Thrush of the fall season on the west side of Briones Reservoir - Bear Creek Staging Area (EBMUD permit required). I heard the whistle call first, then that distinctive "chuck" call at an extremely low volume.  Both birds were within inches of one another. I got brief looks at the first bird, then a great, half-minute, eye-level-within-20-feet view of the second.  My guess is these birds had just arrived or maybe were moving through. 

Between that Hermit Thrush "chuck" note and White-crowned Sparrows singing, it really sounds like fall!

All the Best Birding,

possible SPARROWHAWK sp. over Oakland

Noah Arthur
 

I just had what might have been a Eurasian accipiter circling over my Oakland neighborhood. If I'd have remembered to empty my memory card earlier today I would have nailed it, but my card was full and I couldn't get any identifiable photos. It was a small accipiter that appeared to have unmarked or weakly marked whitish underparts. It first appeared over Nevil and Brookdale Streets, then drifted toward the hills until I lost sight of it circling over the vicinity of 35th Ave./Penniman Ave., half-heartedly pursuing a flock of pigeons. 

Do North American falconers ever keep sparrowhawks?

Excellent Marine Conditions for Seabirds & Marine Mammals

DEBRA SHEARWATER <debi@...>
 

Howdy, Birders,

Shearwater Journeys has just completed six Monterey Bay pelagic trips — September 7, 8, 9, 10, 11, and 14. Monterey seabirds and marine mammals have put on quite a show — and it continued today with some very, very fine marine conditions. We reached 60 degree SST today with clear, dark, deep blue waters. We have some upcoming trips departing from both Half Moon Bay and Monterey Bay. See our program, below. 

On today’s Monterey trip we observed: BLACK-FOOTED ALBATROSS; SOOTY, BULLER’S PINK-FOOTED and BLACK-VENTED SHEARWATERS; RED and RED-NECKED PHALAROPES; SOUTH POLAR SKUA; POMARINE, PARASITIC, and LONG-TAILED JAEGERS; SABINE’S GULLS; ELEGANT, COMMON, ARCTIC, and FORSTER’S TERNS; COMMON MURRE; PIGEON GUILLEMOT; CASSIN’S and RHINOCEROS AUKLETS. 

Along the Coast Guard Breakwater, we found: BLACK TURNSTONE and SURFBIRD. WHIMBREL and MARBLED GODWITS were flybys. The PEREGRINE FALCON was on the radio tower. Eight TRICOLORED BLACKBIRDS circled above the harbor. 

Marine mammals today included: MINKE, FIN, HUMPBACK, and KILLER WHALES; RISSO’S and PACIFIC WHITE-SIDED DOLPHINS; SEA OTTER; and NORTHERN FUR SEALS. Two BLUE SHARKS were seen in the clear, 60 F SST water offshore, as were likely bluefin tuna. 

Other species included on earlier trips included: ASHY STORM-PETREL, including one being chased by a Parasitic Jaeger; and two very obliging SCRIPPS’S MURRELETS. Other marine mammals sighted have included: BLUE, SEI, and BAIRD’S BEAKED WHALES; and SHORT-BEAKED COMMON DOLPHINS. 

There is a lot of food around the greater Monterey Bay area. It seems to be a non-stop smorgasbord for the past four weeks. 

The marine weather looks great! Our full program of remaining trips is below. Spaces are available. I can only be reached by email: debi@...

Re: second attempt of photo of Possible White-winged scoter in Richmond Marina

There is no WW Scoter. A message about it that I wrote in November 2015 keeps posting itself from time to time.  I'm not sending this message out. This old message seems to be repeating somehow.  I have no idea how to prevent this from happening.  I've contacted the Owner of the list for help thinking that the problem may be with Yahoo Groups.  I've also closed my PacBell email account in attempt to stop this from happening again. Finally, there seems to be a glitch when I try to sign on to the group so I'm not even sure that the group as a whole will receive this message.

Bar-tailed Godwit:negative report

Bruce Mast
 

Hey folks,
I finally had a chance to stop by Middle Harbor Park to look for the godwit. The tide was just starting to ebb when I got there and the birding started getting good about the time the light failed. There was a nice assemblage of Marbled Godwits and other shorebirds but no Bar-tailed. Can't rule out the possibility that it was roosting somewhere in the neighborhood and didn't make it back to the mudflats to feed until after sunset.

Pelagic Smorgasbord: Sep 3, 2016 Trip Report

DEBRA SHEARWATER <debi@...>
 

Howdy, Birders,

There is an incredible amount and variety of food offshore at the moment — including pelagic red crabs (in Monterey), squid, anchovies, and krill. Every marine animal from shearwaters to whales to great white sharks — seems to be feeding or looking for food. 
Shearwater Journeys’ latest trip report for September 3, “It’s a Smorgasbord Out There! can be found at this link:

Although our September 3 Monterey trip made it out just fine, we were seriously weathered out on September 4, Half Moon Bay due to near gale force winds and square seas. 

The weather surprised us yet again, today with some gusty winds from the south while a west swell continues. Yet another high pressure system is moving in place over the northern waters. For now, I can’t trust the marine forecast, but if the seabirds turn up anywhere near what folks in Arizona have seen — Wedge-tailed Shearwater, Least and Wedge-rumped Storm-Petrels — well, count me in! 

Monterey Bay looks good for the next several days. Our trip program is listed below:

MONTEREY BAY:
SEP 8 with Mary Gustafson, Scott Terrill, Christian Schwarz, Debi Shearwater
SEP 9 with Mary Gustafson, Rick Fournier, Debi Shearwater
SEP 10 ALBACORE;  with Nick Levendosky, Scott & Linda Terrill, Mary Gustafson, Alex Rinkert, Debi Shearwater (SOLD OUT)

Reschedule - pelagic trip now on Sunday

Alvaro Jaramillo
 

Hi folks,

    

         We have had to change our pelagic trip this weekend to Sunday from the previously scheduled date on Saturday. Both days this weekend look great for weather, and thus far Sunday looks quite nice. It is a few days out and forecasts can be off, but the predictions look to be right on for good weather to get offshore. Things have shifted since we were last out, with Black-vented Shearwater having appeared inshore and likely other warm water birds have appeared offshore. We need to go out and check it out for ourselves, I would not be surprised if Black Storm Petrel has arrived, hopefully the Buller’s Shearwaters are in (maybe Flesh -footed?) and certainly we will be on the lookout for offshore murrelets – Scripp’s, Craveri’s, and Guadalupe in order of increasing rarity. September is peak for diversity offshore, and perhaps you had Sunday available and not Saturday so I wanted to let all know that there are spaces available, and the weather looks good.

Take care,

Alvaro

Walnut Creek bird comments

rosita94598
 

Just a couple of mentions from Walnut Creek.  Monday I took a late ride to Heather Farm Park and found 300 Canada Geese on the north ball fields.  Three of them were actually some of the mixed geese who are in the group, but I did not see the all-white domestic goose which flies with them.

And secondly, this spring the nest box in our patio hosted a family of Chestnut-backed Chickadees.  A total of 3 chicks seem to have fledged.  After a week or so, I removed the nest from the bird house and then noticed that the chickadees re-built a new nest.  Then, a couple of things happened: we went to Yuba Pass with Mt. Diablo Audubon and the homeowners group of painters/roofers finally arrived. 

Over the past weekend I took the box down from the little Japanese maple tree and we looked inside.  There in the bottom was the new nest with a nice soft layer of cottony nest material, but lying in there were 4 small white eggs.  They must have abandoned the nest when the painting/roofing activity reached its height.

It's a bit sad because this was the first time we have observed any attempt to have a second family in one season.

Re: Interesting tanager

Kay Loughman
 

Thanks to all of you who commented on the unusual tanager that visited my yard yesterday morning. Several people suggested a hybrid, with various combinations of Western, Summer, and Flame-colored; Western x Summer was mentioned most frequently. I too had considered the likelihood of a hybrid, but now have another possibility:

My husband, a retired geneticist, suggests the somewhat mottled plumage is likely the result of genetic mosaicism, similar to the process that created the showy leucistic American Robin that showed up in our neighborhood in March 2014: <http://www.nhwildlife.net/album/Unique/slides/AMRO-6837-72-RL.html> and similar (but NOT identical) to the process that creates genetic anomalies (e.g calico cats) in mammals.

A genetic mosaic would allow for those widely-distributed orange feathers (where we might expect yellow) without the need for us to determine family history.

An unusual tanager spent two minutes (only) visiting one of the
coffeeberry plants in our yard today. I was set to call it Western
male, first fall, until I looked more closely at the photos I took.
The things I noticed were that the orangish feathers were scattered
well down the chest and onto the belly, flanks and upper tail
coverts. Also, the upper wing bar was decidedly orange. I know
tanagers can vary quite a bit in their coloration, but this is outside
my experience.

This part of my north-facing hillside property barely gets any sun
after mid-August, so the photos are shadier than I'd like. (The upside
is that it takes the coffeeberries longer to ripen, so they're often
available to the birds later than plants in sunnier parts of the yard.)

Comments appreciated.
