Black-throated Gray Warbler, San Leandro Creek

Patricia Bacchetti
 

Hi all;

Scouting the Dunsmuir area of the Oakland CBC circle turned up a few interesting birds today. A creek restoration effort by Alameda County Public Works is going on along parts of San Leandro Creek near downtown San Leandro. At Haas and Bancroft, a bridge crosses the creek above the newly planted alders. A male BLACK-THROATED GRAY WARBLER was fly-catching from an oak tree as I crossed the bridge, as well as 2 TOWNSEND'S WARBLERS, several YELLOW-RUMPED WA, and a BROWN CREEPER. The Black-throated Gray will be a good count week bird if we don't find it again tomorrow. Locals told me that they hear Great Horned Owls calling from the eucalyptus early in the morning, as well. The TURKEY VULTURE roost along Bancroft only had 2 birds lingering in the afternoon, but 2 weeks ago there were over 30 birds early in the morning.

Another section of the creek is being restored behind the Memorial Park area, at Huff and Callahan, with 2 TOWNSEND'S WARBLERS present with the usual assortment of Yellow-rumps and chickadees.

The beautiful weather should make for a very pleasant CBC day,

Prairie Falcon at Ardenwood Historic Farm, Fremont

scfloyd2000@...
 

This morning, Rich Nicholson and I previewed a section of tomorrow's CBC by birding Ardenwood Historic Farm in Fremont. In addition to about six Red-Tailed Hawks, a Sharp-Shinned Hawk, and a Cooper's Hawk, we saw one, maybe two, Peregrine Falcons, a Merlin, a kestrel, and a Prairie Falcon. A very poor digiscope of the Prairie Falcon is at the link below.

Head Naturalist Trent Pearce joined us on the walk and got much better photos of the Prairie, which with his permission I will share when I receive them.

The Prairie Falcon was perched near the top of a eucalyptus along the main trail northwest of the mansion. No sooner than we got on it and rushed to take photos, a resident Peregrine Falcon rousted the smaller bird and, both screaming, drove it from its territory. We lost the Prairie as it flew northeast, and we were unable to find it again.

Later, at Coyote Hills, we found a Red-Shouldered Hawk and two White-Tailed Kites, bringing us to a total raptor count of 9 species for the day.

Bay Farm Island

rfs_berkeley
 

This morning I swung by Bay Farm Island for some CBC scouting. Of interest:

Lesser Yellowlegs: Wetland along Harbor Bay Pkwy at point where the road turns north along the coast. Just south of the Pete's Coffee Headquarters.

Orange-crowned Warbler: In roadside plantings along Harbor Bay Pkwy and S. Loop Rd. (near Raider's Headquarters)

Geese: Lydecker Park had ~100 grazing Canada Geese at 10 am; Among them a White-fronted Goose, 2 juvie Snow Geese and an adult White Goose that at first glance I took for a Ross' as it was distinctly smaller than the two Snows. I now wonder if it isn't the apparent hybrid white goose that was seen at Oakland Middle Harbor last season**. The bird's bill is intermediate in shape & size between Ross' and Snow; and the black smile line, while certainly noticeable, was thin. The 2 young Snows stuck close together, but the adult white goose did not seem to associate with them, particularly. The bird seemed in all respects intermediate. Thirty minutes later half the geese were gone including the 4 noteworthy

** or perhaps two seasons ago?

White-Throated Swifts and Golden Eagle Alvarado Park, Richmond

Sheila Dickie
 

On Friday, December 16 mid to late afternoon, there was a large flock of White-throated Swifts flying high above the Wildcat Canyon Trail at the Alvarado Park end in Richmond. 
 
On Thursday, December 15, mid afternoon, while walking the same trail I saw a very big bird flying high up in the sky and headed east which looked like a Golden Eagle.  Later in my walk a woman came up to me and said that earlier she had seen what looked to her like a young Golden Eagle flying above the parking lot at Alvarado, apparently very interested in remote-controlled racing cars that two men were playing with in the parking lot.

Valle Vista/Pinehurst

Jeff Acuff
 

This morning, pre-dawn, I worked Pinehurst Road near Canyon.  In addition to several great-horned owls, I found one northern saw-whet owl that called for about 20 minutes, first from one side of the road and then from the other.
After daybreak, I moved to Valle Vista Staging Area (EBMUD permit required).  Where the Kings Canyon trail reaches the tip of Upper San Leandro Reservoir (there's a bench for relaxed birding), there were 20 (!) Wilson's snipes working the mud flats along the water.  
Other fun finds along my walk included 2 hooded mergansers and 3 ring-necked ducks at the bridge where wood ducks are often found.  (There were a pair of them too.)  In this same area there was a varied thrush and there was at least one red-breasted sapsucker in the pine/eucalyptus grove leading up to this area.
Good birding,Jeff AcuffLafayette

Re: Clay-colored Sparrow at Oakland Middle Harbor Shoreline Park (12/16)

Hi all,

I posted eight cropped but otherwise unaltered photos in a new folder on this site, but it may take a while for them to be approved by the moderator. Meanwhile, I'm posting the links to three photos on my flickr site here:

http://www.flickr.com/photos/zonotrichia/6523452621/

http://www.flickr.com/photos/zonotrichia/6523452225/

http://www.flickr.com/photos/zonotrichia/6523451897/

These photos have been cropped and had "auto contrast" and "auto sharpen" applied... I'm less certain about Clay-colored versus Brewer's now, although I guess I still favor Clay-colored. Some of the photos show somewhat worn rectrices, which makes me think it's not the same bird I saw a month ago at this park (which was molting it's tail feathers)...

Comments, either here or off-line, would be very welcome.

I was able to get a number of decent photos this time and will post them tonight to get confirmation or correction of the ID from the group.

Also seen today were the continuing immature GREATER WHITE-FRONTED GOOSE (noted here for months now) and a single minima-type CACKLING GOOSE, both hanging out with the Canada Goose flock.

The Wilson's Snipes continued today (Dec14) from 9Am till late afternoon
at location mentioned by Steve Zamek in yesterday's posting. I also saw
a pair of White-faced Ibis around 11AM, while driving towards kiosk from
Quarry Parking Lot. The pictures can be seen at link below. The pictures
are geotagged for the location.

Eurasian Collard Doves (& Black-shouldered Kite) at Crown Beach, 12/7 (& 11/29)

Bob Sikora
 

Found a small flock of Eurasian Collared Doves (6 or 10 birds) in what I think are Tecate Cypress just e. of the Crown Beach visitor center at midday on 12/7. They seemed very tame and allowed an approach to within 20' or so. They were not there today at 11AM. Photo at:

http://bobsikora.smugmug.com/Photography/Crown-Memorial-State-Beach/20596944_MX4JNC#1632548801_87SML94

Also, saw a Black-shouldered Kite hunting near sunset at the Elsie Roemer Sanctuary on 11/29. A couple of poor record shots at:

http://bobsikora.smugmug.com/Photography/Crown-Memorial-State-Beach/20596944_MX4JNC#1632511003_RH6cfDF

Ed, if you catch this, it was probably the same bird.

It dawned on me that the reason we have not been birding for 15 yrs or so is because we had dogs during that period. We lost the last one about a month ago. We are slowly coming up to speed. Sorry for the delayed posts.

Common Loon and Townsend's Warbler, Quarry Lakes RP

scfloyd2000@...
 

On Monday afternoon, a Common Loon was in the south bay of Horseshoe Lake at Quarry Lakes Regional Park in Fremont. A Townsend's Warbler was in the trees near the info kiosk on the midway trail on the east side of the lake. A calling Belted Kingfisher was in that area as well. A banded Brown Pelican was on the swimming beach (I reported the banded bird).

To reach Quarry Lakes, from Paseo Padre Parkway go northeast on Isherwood Way. Or from Alvarado-Niles Road (which is Niles Blvd. at this point), go southwest on Osprey and then south on Quarry Lakes Road. Park by the buildings next to the swimming beach and walk south on the paved trail; BART is on your left, Horseshoe Lake is on your right.

Oyster Bay gulls 12/13/11

Lori Arthur <loriarthur61@...>
 

At O.B. this evening there were a few small remnant sparrow flocks in the vicinity of the entrance, but nothing like yesterday's flock, and no Clay-colored. I also didn't see any vagrant gulls, but I might easily have overlooked them, so I encourage other birders to visit Oyster Bay in the late afternoon for the fly-out.
 
Huge numbers of gulls exited the landfill, seven species plus hybrids. I'm very bad at ID'ing flying gulls, and many went unidentified. Of those that I could ID, most were GLAUCOUS-WINGED, WESTERN, and CALIFORNIA GULLS as well as WESTERN/G-WINGED HYBRIDS, with much smaller numbers of other species: two adult AMERICAN HERRING GULLS, a few MEW GULLS, and one RING-BILLED GULL. I saw two definite adult THAYER'S GULLS plus many possibles, but had a hard time distinguishing Thayer's from Glaucous-winged. One bird had a wingtip pattern like Thayer's but medium-gray rather than black, and one "matchstick-billed" 2nd-cycle gull looked like Glaucous at first, but had subtle gray markings on the outer primaries like Glaucous-winged.

Snipe at Coyote Hills

Steve Zamek
 

A pair of WILSON'S SNIPE were foraging this morning in the grass in front of the Visitor Center at Coyote Hills Regional Park (near the Quail Trail). They were remarkably tame, as they didn't flush when walkers passed within about 20 feet of them.

Clay-colored Sparrow at Oyster Bay Regional Shoreline 12/12/11

Lori Arthur <loriarthur61@...>
 

This afternoon a CLAY-COLORED SPARROW was with the huge flock of WHITE-CROWNED and GOLDEN-CROWNED SPARROWS at the entrance to Oyster Bay Regional Shoreline (this is the entrance at the end of Neptune Drive in San Leandro). The sparrow flock was frequently spooked by dogs, and returned to the ground in a different location each time, but always on or near the flat grassy area at the entrance to Oyster Bay Shoreline. I had sightings of the Clay-colored at the northeast corner of the grassy area and in the vicinity of the broken water fountain at the west end of the grassy area, always with the Zonotrichia flock. It was a poorly-marked bird, approaching Brewer's, but had a distinct pale crown-stripe. A few SONG SPARROWS were also present.
 
Gulls seen flying from the landfill to nighttime roots were MEW, CALIFORNIA, WESTERN, GLAUCOUS-WINGED, THAYER'S, HEERMANN'S, and various hybrids involving Glaucous-winged. American Herring was conspicuously absent and last week's Glaucous did not reappear, but the first-cycle Heermann's was a nice surprise. If you visit Oyster Bay for gulls, be sure to arrive at about 3:30 PM, and station yourself on the grassy slope above the entrance for the evening fly-out. From about 3:40 until dusk the gulls parade through the sky, presumably going from the landfill to their nighttime roosting areas.

East County Car birding

Steve Huckabone <shuckabone@...>
 

I found two Rough-legged Hawks in Eastern Alameda County. One was at the end of Midway Rd as previously reported, another was along Lindemenn Rd.
Also of interest were 3 Cattle Egret in a alfalfa field at the corner of Mountain House and Kelso Rd. The Cattle Egrets were actively foraging amongst a flock of sheep sometimes standing on the backs of the grazing sheep.
Good birding.

In the previous email the "A "got left off of picnic area A, where the Mew Gull was. Sorry.


I saw an adult Thayer's Gull and a Mew Gull at Fremont's Central Park 12/10. The Thayer's was at the boathouse dock (off Paseo Padre). The Mew was on a small dock near picnic area A (near the end of duck island which is closest to Aqua Adventures, off Paseo Padre). A lovely sight, north of the boathouse, was a group of about a dozen White Pelicans feeding in unison, like a water ballet. It would make a nice video.

I am doing the CBC at Central Pk. on the 18th. If anyone sees any special birds there before the count or within 3 days after it, please let me know. Of course, photos would be especially good.
If you want to join us for the CBC, let me know.
Good birding to you!
