Today while searching for Blue Grosbeaks on Patterson Pass road I spotted my first ever Patterson Pass Rd. Sharp-shinned Hawk at road marker 6.21.
I did not see or hear any Blue Grosbeak.
Typically the Blue Grosbeak arrives along Patterson Pass Rd. on or near April 16th.
Lark Sparrows, Logger Head Shrikes, Western Kingbirds, and a single Bullock,s Oriole.

Ed Levin Trip
This morning near 10AM in the Spring Valley unit of Ed Levin park in the
equestrian staging area.
Theresa McGovern and I had 4 Bullocks Orioles in the flowering red bud
eucalyptus tree feeding.
This tree was very poplar through the morning.
It appears to be a major food source for many Yellow-rumped Warblers,
Red-shafted Flickers up to 3 at a time.
Red-winged Blackbirds, Nuttall Woodpeckers, Acorn Wood peckers, Anna's and
a single Rufous Humming birds.
Near 11 AM a Sharp-shinned Hawk took over the tree for what seemed like a
minute, allowing for a good study period.
Barn, Tree, Northern Rough-winged Swallows were all present along with
Western Blue Birds + Song and White-crowned Sparrows.
Looking up slope southwest from the equestrian area past the Blue Bird nest
boxes a fly by Lazuli Bunting made an appearance.
Looking up we had six Red-tailed Hawks and a single Golden Eagle.
On the way out we stopped by the Flag Pole and parked.
Across from the parking area we watched and listened to a Pacific-slope
Flycatcher for maybe an half hour.
Near the wooden fence and iron gate road side there were two Bewick's Wrens
carrying nest materials and being very quiet.
Another two Bullocks Orioles appeared also.

Callippe Golf Course trip Pleasanton April 1'09
This morning I lead a birding walk along the mitigated hills sided of The
City of Pleasanton Callippe Golf Course in Alameda County.
There are several pair of Western Kingbird along the two mile fence line
that were gorging themselves with Painted Ladies and i think California
Tortoiseshell Butterflies.
The golf course is named after the Callippe Fritillary Butterfly, which
lives on the mitigated lands.
Also seen, Golden Eagle, several Red Tailed Hawks, nine (!) White-breasted
Nuthatch's, six Bullocks Orioles ( two females already), one Yellow-billed
Magpie.
