Yesterday, 9/3, Nancy and I made a morning trip to Contra Loma R. P. In addition to the usual suspects, we had the following birding highlights:
Caspian Tern (3)
Yellow Warbler (at least six)
Lark Sparrow (~8)
There are many Mallards at the reservoir, all in eclipse plumage and feathers are widespread.
My apologies for the late posting.
Note: Contra Loma R. P. is open on a walk-in basis only, vehicles are not allowed into the park. The closest parking is at the end of Frederickson Lane. Bathrooms are closed.
