RE: [SBB] Volunteers needed for SF Bay shorebird survey Nov 13-15 (23-25raindates); volunteers also sought to lead shorebird ID trainings
- Hi Mike,
If I'm not mistaking the shorebird count has been going on since the
I'd like to suggest that it is time to expand the habitat count area's.
With consensus' maybe its time to begin including interior habitats.
Certainly throughout the seven or nine bay area counties there are many
interior wetlands, flood plains, detention ponds, wet pastures, etc. which
I realize the numbers are not in the bayside volumes - but these area are
seasonal IBA's miles from the bay side.
Speaking for myself only, here in eastern Alameda County there are some
interesting habitats to count, especially if we have rain before the
Novemeber13-15 count days.
Let me how the count coordinators feel about this suggestion.

months. The San Francisco Bay is one of the most important wintering sites
for North America�s shorebirds, holding higher proportions of the total
wintering and migrating shorebirds than any other wetland on the U.S.

Least Sandpiper (11%), American Avocet (10%), and Willet (8%). Counts for
Western Sandpiper and Dunlin in the area between San Francisco and Palo
Alto were much lower than a decade ago. Over the past 15 years there has
been a clear shift in the distributions of medium and large shorebird
species to the North Bay. The biggest increases occurred along the northern
shoreline of San Pablo Bay, where large tracts of retired salt ponds have
been opened up to tidal action.

based on sound science.
