Gray Lodge Waterfowl Refuge, Butte Co., Calif.
Characteristic gurgling flight sounds. Some
indulged in a little dancing on the
ground but not much. Snow and White
Fronted Geese occasionally rose by the
hundreds of thousands, circled and set
back down. Even with these huge
numbers it seemed only a small part
of the birds flew. Pintails, in the open
shallow water, rose by the thousands
also, and Mallards in equally large
numbers flushed from the cover of the
tules and rushes. Almost invariably
the pintails rose in open water, Mallards
in the edge cover. Baldpates were fewer
in numbers, but still common, and were
mainly in open water. Shovelers were
fewer yet, and were mainly at the edge
of the tules + cattails, often going in and
out. Teal occasionally flushed with the
Mallards, flew straight away so as to
hide field marks. I didn't get a positive
make on any Teal, although Cinnamon
were identified by others. Coot were
everywhere, in all the open water, canals,
and sloughs, and feeding on land. Canada
Geese were scarce. Saw a small flock
flying, and 2 on the water. Dead birds,
mainly Pintails + Snow Geese, were commonly
found lying around. Evidently they had
been wounded, and had returned to the
refuge to die. Signs of birds eaten by
predators were fairly common. Some of
these were probably dead + eaten by scavengers.
