[EBB Sightings] Bonaparte's Gulls, Dumbarton Bridge; Alameda Co. big year

Hi all:

Bonaparte's Gulls continue in the hundreds on the
north side of the Dumbarton Bridge (Access via the
south side of the bridge and Don Edwards NWR). A great
opportunity to view large numbers in non-breeding
plumage, and presumably, watch their change-over for
the next  two months.

For those participating in the Alameda County Big
Year, please zap me your numbers.  For those sitting
on the fence, there's plenty of time left in the year.
Don't worry about a late start.  The more the merrier.
Bruce Mast's tracking sheet is still available, free
of charge.

Best regards,

Bob Power
