Oh, you might get to see another this fall. :-)

After not getting to the UTC in spring for a couple of years, I find a real need
to get back to remember what these birds actually look like.

I'm still trying to figure out how Brian could see Least Terns in Alameda from
Heron's Head park. :-)

I have a very naive question. It's been widely assumed that PSFL breeds in SF,
presumably in McClaren if not other spots in the city. Why then have I never
hear the full PSFL song in SF?

I would tend to agree, although I'm pretty sure I recall seeing both sexes
of a Black-headed Grosbeak pair in Glen Canyon in '98, one of which was
carrying nesting material. I may have even found the nest, but never saw
any young (or cowbirds, for that matter), probably because I was too
engrossed in finding my next year bird. :-|

This year there are three Bullock's orioles present, including at least one
female if recollection serves me. Maybe we'll get lucky this year...

6.6 [SFBirds] Re: [SFBirds] That gull
I agree with Harry; most of these birds are invariably very worn GWGU,
particularly if they are badly worn.

Did you see the photo of the putative ICGU in Monterey?

6.10 - 11 Yuba Pass
I was joined by Stephen Davies and Katharine Feldman for the Saturday portion of this classic trip. While we didn't manage to see anything particularly rare, it was quite a nice trip for photography.

Everyone's favorite bird, I found this AMERICAN DIPPER flying up the river as I returned to Sierra City on the 10th. I headed out first thing the next morning and found the bird sunning itself in the early morning light against the still-dark water. It sat quite cooperatively as I was able to get relatively close, partially hidden by the embankment of the highway. When was the last time you saw the wing linings of a dipper?

I was driving along Mountain Quail road when I noticed a pair of MOUNTAIN CHICKADEES going in and out of a stump right near the road. I returned the next morning and set up shop, partially hidden by a sapling near the stump. While I struggled to catch the birds coming in and out of the nest hole, I had much better luck getting on one while it was waiting with food for the nest exchange with its mate.

A WILLET rarely garners a second glance in most parts of California. It's too bad, because the intricacy of the bird in alternate plumage such as seen here on Marble Hot Springs road is really quite lovely.

The Fox Sparrow complex is often mentioned good candidate for more splitting, and this THICK-BILLED FOX SPARROW shows why with its enormous bill and gray head. This bird was singing more or less non-stop from a willow thicket near at Bear Trap Lake, an exciting 4WD journey north from Yuba Pass.

I've always found CHIPPING SPARROWS to be a bit of an enigma. Seemingly equally at home in lucious, wet montane habitat at Yuba Pass and in arid Juniper/Sage at Red Rock Canyon near the Nevada border, I often overlook it because of the similarity in its song to Dark-eyed Junco. Thie bird was vociferous not far from the parking lot at Yuba Pass.

Hard to see and harder to photograph, this mated pair of WILLIAMSON'S SAPSUCKERS were breeding at the small pond just east of the highway on the to road to Salmon Lake Lodge. I think they have breed there for several years running. Black-backed Woodpecker is also regular here.

Way out of their current range, I'd guess. I don't have Grinnell and Miller
here, but I think NOPA historic range was well up the coast, much farther than
they did recently. Also, NOPA are more or less regular, though rare, breeders
in Monterey County, if recollection serves...

Unfortunately, I'd guess that their chances of success are probably about as
good as the Olive-sided Flycatcher in the wash... :-(

6.16 [SFBirds] Re: [SFBirds] ruddies
I thought small numbers of RUDU breed in various locations in the Bay Area.

Any idea if this is simply post-breeding dispersal or possibly the beginning of
a southward movement for these birds?
