Costa's Hummingbird, Western Tanagers
Mon, 7 May 2001 10:17:12 -0700
From: Rebecca Freed
I heard the Costa's Hummingbird teakettle-calling somewhere around my elm trees, about 4 doors west of its usual haunt on Berkeley Way in Berkeley, around 5 last night (Sunday). I couldn't spot it - I think it was just passing through - so I don't have any more info about what it might be using to feed.
I also heard Western Tanagers repeatedly, and kept convincing myself that I was being tricked by a European Starling or Brown-headed Cowbird.

Black Swan
Mon, 07 May 2001 10:29:23 PDT
From: Erik Stromberg
I saw a Black Swan at Shollenberger marsh in Petaluma (Sonoma County) yesterday and I had never seen one before. I assume it is an escapee. Can anyone shed some light on this? And can some one explain to me the two Mute Swans also? I thought they were only East Coasters?
Thanks
Erik

Black Swans are native to Australia, Mute Swans to Europe. Perhaps they're all escapees.

Costa's Hummingbird continues

Tuesday, May 8
The Costa's Hummingbird was on the wires in front of 1611 Berkeley Way, Berkeley,
at 8:15 AM today. It dove downward and northward. Since
it also sometimes perches on two tall trees in the middle of the block bounded
by Berkeley Way, California St, Hearst Ave, and McGee Ave, I assume there's
a food source in one of the back yards on that block.

Mines Rd, San Antonio Rd, Del Puerto Canyon

From: Mark Eaton
[Apologies for cross-posting, but the Mines Road circuit southeast of Livermore spans three different mailing lists.] On Sunday, May 6th, I too did the Mines Road circuit and had reasonably good success. Of particular note were the estimated 35 Western Kingbirds seen throughout the day at various different locations, though most of them were confined to Del Puerto Canyon Rd.
Unusual/migrants:
Stanislaus County:
4 or 5 Cassin's Kingbirds at milepost [MP] 3.7 and another at MP 9.9 along Del Puerto Canyon Rd. Several were calling, but I did not see any direct evidence of nesting behavior.
MacGillivray's Warbler, singing at MP 17.7 in the willows.Santa Clara County:
Western Tanager, calling at MP 22.3 along Del Puerto Canyon Rd
Orange-crowned Warbler, singing at MP 23.3
Western Wood-Pewee, at the Fire Station just south of the junction
Wilson's Warbler, a silent female at MP 24.7 along San Antonio Rd (AKA the summit)Regular occurring species of interest:
Stanislaus County:
Grasshopper Sparrow, 2 at MP 1.8 along Del Puerto Canyon Rd, just west of a cattle guard near a small stream. I flushed one and another perched on the barbed wire obligingly for a rare photograph.
Golden Eagle, one at MP 3.7 along Del Puerto Canyon Rd
Rufous-crowned Sparrow, singing at MP 3.7 along Del Puerto Canyon Rd
Costa's Hummingbird, a male perched high in a tree at MP 5.4Santa Clara County:
Wood Duck, in the usual pond on the south side of Del Puerto Canyon Rd at MP 23.8
Lewis' Woodpecker, at least two at MP 0.3 of San Antonio Rd
Lawrence's Goldfinch, at least three at the Fire StationAlameda County:
California Thrasher, singing from the top of a mature oak tree at MP 10.68 along Mines Rd Phainopepla, at MP 5.65 along Mines Rd

Mitchell Canyon
Tue, 08 May 2001 18:44:11 PDT
From: Jim Tietz
Hi-
Peter Stevens and I went birding today at Mitchell Canyon [in Mt Diablo State Park, south of Clayton]. Before parking the car, we stopped at Mitchell Canoyon Ct and spotted the male Phainopepla flying overhead. We hiked up the Mitchell Canyon Road to the top of the Red Rd and then took a left and went to top of the hill. The numbers of migrants have noticably dropped off and the activity level was down today as well due probably to the high heat. We still managed to find 61 species though. A few Yellow Warblers have arrived. The same Gray Flycatcher or another is present near where the last one was. This one was about 150 meters from the last in the blue oaks at the top of the Red Rd. Later on it was in the large oaks to the right of the top of the Red Rd. There were still numerous Black-headed Grosbeaks and Lazuli Buntings in this area as well.
Good birding
