For more than 2 decades Golden Gate Audubon Society has sponsored field trips at this time of year in Wildcat Canyon Regional Park. Following the usual route we started today (Saturday) at 8:00 AM at the end of Rifle Range Rd, where we noted the nesting Cliff Swallows, then followed the trail down to Wildcat Creek, crossed over, and hiked up Havey Canyon on the opposite hillside, north through the grassland, then back down to the creek. About 6 miles round trip. Observations by sight or sound were:

Yay, I saw it today! It was there at 3 PM, briefly. I had just given up, turned around to look again - and there it was. Ten seconds later, it flew away.
Thanks :)

Hi-
On 12 May, I helped lead a trip for the Napa-Solano Audubon Society to Castle Rock Regional Recreation Area. Most of the group turned around at the gate that borders Mt Diablo State Park at noon, but 3 of us continued on another mile to the pond. Over the entire trip, we encountered 62 species and found 7 nests. No activity was seen at the Cooper's Hawk nest. Most abundances noted below were estimated.

Hayward Shoreline

The following was seen at the Hayward Shoreline mostly today, but a few yesterday:
Cattle Egret - 2, seen on an apparent nest yesterday, seen carrying nest material to the vicinity of the nest seen yesterday. Nest in bullrush was very hard to see. You had to be in the right spot to see it and the bird on the nest had to be positioned just the right way to identify it.
Black Skimmer - 2, seen both days
Spotted Sandpiper - 2 seen today
Yellow-headed Blackbird - 3 seen today, all were females
Bank Swallow - 1 seen yesterdayToday a tern was seen that may have been the Arctic Tern X Forster's Tern that was fledged 2 summers ago, but the bird was either seen in flight or when on the ground, it was usually sitting on the ground which made for a hard time seeing the 4 bands (2 on each leg).
The Arctic Tern was not seen today.
Good birding
Bob
