I spent today birding eastern Contra Costa County.
The highlight was a pair of Redheads on Clifton Court Forebay (access via
Clifton Court Road off Byron Highway). Bring a scope and be prepared to
patiently look through large numbers of scaup.
There were also two Ferruginous Hawks (one at the east end of Delta Road,
just before the turn north to the Holland Tract; the other near Byron
Airport, just north of the junction of Armstrong and Byron Hot Springs
Roads). The latter location also had a flock of 75 Long-billed Curlews.
