[mou] Re: [CALBIRDS] Sabine's Gull migration

[Todd Easterla]

Hey,

Sabine's Gulls seem to be annual at Lake Tahoe from mid September to early
November (mostly- North Lake Tahoe). Yesterday there were three immature
Sabine's Gulls at the China Lake Sewage facility ponds. Also, on the way
home I stopped at Lake Crowley in Mono County and had three immature and one
adult Sabine's Gulls at the Southwest portion of the lake. Weather obviously
has allot to do with the inland sightings as well. Yesterday there was a
moderate Southerly flow up there. Most of my sighting's of these guys are
during a Southerly flow and or stormy weather.
