I like to issue a correction to my posting earlier today of the Hermit
Thrush in Colombia.
That needs to be a Grey-cheeked Thrush, not a Hermit Thrush.
I hope that I haven't confused anyone who may have checked the range map for
the Hermit Thrush range distribution.
Hermit Thrush is rare in Colombia.
The Grey-cheeked Thrush is a wintering species in Colombia at this time of
the year.
Meanwhile, I checked the Cornell Bird Cast Site, and 241,000+ species passed
over Marin County last night, April 19th.
The Swainson's Thrush is shown as beginning to arrive OVER Marin County.
I was curious, so I checked Birdcast using two states where Grey-cheeked
Thrushes migrate through Wisconsin and Louisiana for the Grey-cheeked Thrush
migration using the Mississippi flyway.
The Grey-cheeked Thrush isn't shown arriving in the continental USA just
yet.
This is interesting, too, since on my annual field trip to Nome, Alaska, in
late May, the Grey-cheeked Thrushes have arrived and are on nesting
territory and singing.
Birding is a great hobby, pastime, and profession.
With Appreciation,
Rich Cimino

Subject: [northbaybirds] Ash-throated Flycatchers Olompali State Park
Spring has arrived in Olompali State Park.
Yesterday, Saturday, between 10 AM and noon, up to three calling and located
Ash-throated Flycatchers were in the park.
Two Ash-throated Flycatchers were calling in and around the entrance path up
to the walnut orchard, and the third was calling from the southwest side of
the parking lot.
Also heard was a single singing Warbling Vireo.
I did try to locate the two wintering Red-breasted Sapsuckers, but I was
unable to, they may have left the park en route for the Sierra Nevada's and
further north.
A side note:
Having just returned from a field trip to the Eastern Andes Mountains of
Colombia, my group saw several Canada Warblers, Hermit, and Swainson
Thrushes moving in their northern migration.
A second side note: Yesterday afternoon, from 2 30 to 5 PM, behind my home
along Corte Madera Creek (near Niven Park, Larkspur), two Forster's Terns
and a Caspian Tern were diving as the high tide was flowing upstream. During
the low tide, Greater Yellowlegs and Long-billed Dowitchers were present
feeding on the mud flats.
