Western Gulls were largely idle, but
occasionally one would approach a Willet
and frighten it off when the willet had in
having some difficulty extracting an object
from the mud. This appeared to be an
attempt at pirating but the wilets
appeared to get away with the goods in
each case observed.
Wilets often pocked their bills into the
mud clear up to their foreheads + appeared to
be struggling to reach a deeper object or
to remove a big one. The Black-bellied
Plover appeared to pick objects up from
the surface and not to probe at all.
Further out from shore was a larger
gathering of ducks, again mostly Canvasbacks
and a few Scaup. Along one margin was
a group (20) of Ruddy Ducks. One Western
Grebe floated alone 40 ft. off shore.
A group of 20 coots, another of 4 Western
Grebes, and a single Loom (sp?) swam in the
marina dock area at dusk.
