[EBB Sightings] Mt. Diablo Audubon Field Trip Martinez

Mountain View Sanitary District has a wonderful property between I-680 and 
the Shell refinery.  We walked around there today with Dick Bogaert, their 
biologist.  What a pleasant morning.  We also checked out McNabney Marsh in 
Waterbird Regional Preserve, a property of the East Bay Regional Park 
District.  This is to the east of the freeway.  Altogether we had 60 
species, sorry Jean, two Gadwalls flew in just after you left.

It was a 5-Heron day, but no Bitterns.  Four raptors were seen in Mt. View 
Sanitary, Red-shouldered and Red-tailed Hawk, an American Kestrel and an 
Osprey.  Over McNabney Marsh we added Turkey Vulture, White-tailed Kite and 
Northern Harrier.  Seven other duck species were also seen, none of them 
particularly rare.

All the ducks must be in the south part of the Bay, at least it seemed like 
that Saturday.  Our trip there had 17 duck species including Hooded 
Merganser, Eurasian Wigeon, Barrow's Goldeneye and Blue-winged Teal.  We did 
not find the previously reported Redhead.  That field trip took in the 
Charleston Slough area, Shoreline Lake and the ponds at Radio Road in 
Redwood Shores.  A total of 82 species were recorded, many of them noted in 
Yahoo Groups South Bay Birds.
