    Hi all,
    Sorry for the delay on this. I participated in the
    Contra Costa CBC on Saturday on the 15th, the Hayward
    CBC on the 16th and the Eastern Contra Costa Count on
    the 19th.
    On the 15th at Mallard Reservoir north of Concord (no
    public access,) I had five Surf Scoters (might be the
    first I have seen there in the 18 years I have done
    this) and a young Red-necked Grebe (a count first). A
    male Blue-winged Teal was along Waterfront Rd. in a
    pond south of the railroad tracks. To access this area
    you need to go through the Tesora Refinery security
    checkpoint on Waterfront Rd. and tell them you want to
    go birding. Both Sora and Virginia rails are abundant
    along this road, as is the maxillaris race of Song
    Sparrow.
    
    Later in the day Bruce Morad and his wife were kind
    enough to take me out in their boat to check the
    southern shoreline. An immature male Barrow's
    Goldeneye was mixed in with a flock of about 200
    Commons and at least 1100 (!!!) Surf Scoters were near
    the docks of the Concord Naval Weapons Station.
    Massive numbers of ducks, mostly scaup and goldeneye,
    were rafting in the area, mostly within Benicia CBC
    airspace.
    
    The last I had heard, the preliminary total for the
    count was 155, just a couple shy of the record. 
    
    On Sunday I covered the Hayward Regional Shoreline
    north of Winton Ave., with Heller Stanton in tow
    during the morning. Birds of interest included 5
    Ross's Geese and a Snow Goose on the sealed landfill
    north of the channel at the end of Winton Ave, 20+
    Aleutian Cackling Geese at the same spot (the geese
    flocks here roam habitually so some of these birds
    might not always be at that location), 2 Greater
    White-fronted Geese at the San Lorenzo Community Park
    duck pond (a real garden spot), a male Eurasian Wigeon
    and a hybrid male wigeon on the bay near the sewage
    treatment plant near Grant Ave, a Red-throated Loon on
    the bay in the afternoon (loons are very hard to come
    by in my section there), two Common Moorhens in the
    golf course pond adjacent to  San Lorenzo Community
    Park), the continuing Tropical Kingbird around the
    channel east of the end of Winton Ave (easier for us
    to see by turning into the Crate and Barrel Parking
    lot and driving to the channel; if a guard hassles you
    it wasn't my idea), and two Lesser Goldfinches around
    the substation at the parking area on Grant Ave. 
    
    The highlight of the day was a very obliging Lapland
    Longspur on the landfill north of the channel at the
    end of Winton Ave. Although Bob Richmond routinely
    finds longspurs in the area in fall, the grass is
    normally too tall by this time of year and they
    haven't been found on the count in over 20 years, I
    think. The bird was with a flock of about 20 Horned
    Larks and was usually on the slopes of the landfill
    around the southwest corner. There is no vegetation on
    these slopes so the longspur is completely vulnerable
    to leisurely scopeviews and digiscoping. 
    
    Yesterday I was joined by Jim, Josiah and Andy on the
    Eastern Contra Costa County CBC. My area is around
    Holland Tract and Orwood Rd. east of Knightsen. Recent
    rains had left more standing water than is typical for
    this early in the winter and the waterbirds responded
    in a big way. Numerous Tundra Swans and Sandhill
    Cranes were in the area, as well as lots of white
    geese (including at least two blue-phase Snow Geese)
    and hundreds of Aleutian Cackling Geese. Raptors were
    well represented with at least 5 Ferruginous Hawks, a
    Rough-legged Hawk, a Merlin and a Peregrine. Jim Tietz
    spotted an ad. White-throated Sparrow, as he often
    seems to.
    
    The highlight was an American Redstart, first found by
    Jim and Josiah in some willows and blackberry brambles
     on Delta Rd. shortly before the marina at the east
    end of the road. So, heading east on Delta Rd. from
    Hwy 4 in Brentwood, go several miles to a 90 degree
    left turn. After crossing a bridge and dropping onto
    Holland Tract, the road turns sharply to the right.
    Continue through the first marina to a 90 degree right
    turn. About halfway between this right turn and the
    next left turn, check the willows and brambles on the
    east side of the road. The bird gave it's loud chip
    fairly often.
    
    I had to leave for work at noon but i'm sure the three
    of them found some other goodies after I left. 
    
    Happy holidays,
