[EBB Sightings] Bonaparte's Gulls

Hi all:

205 Bonaparte's Gulls were in the salt ponds on either
side of the Dumbarton Bridge today at 2:00.  
I drove out Marshlands Road to its western end,
parked, walked north under the bridge and surveyed
pond N4.  190 of the gulls were here, actively
foraging.

Another 15 birds were in N3, the pond at the end of
Marshlands road on the south side of Hwy 84.
Marshlands is accessed via Don Edwards NWR off of Hwy
84's Thornton Ave. exit.

Good birding,
