Subject: [centralvalleybirds] yesterday's Tall Forest bird survey results; an interesting jay hybrid
Dear Birders,

After several preceding days of very slow birding (an American redstart in
a female plumage on Friday bucked the trend), I didn't hold out a lot of
hope for riveting birding on yesterday's monthly survey behind the Farm
Center gate. Chris Conard helped out, and he picked out more than a few
things that somewhat redeemed the outing. The encounter rate was poor:
there were several longish blocks of time that were just dead. The more
interesting things were these:
greater white-fronted goose- 1 (my FOS had been the previous day)
sandhill crane- 9 (FOS, a late date for that)
western wood-pewee- 3
dusky flycatcher- 1
western flycatcher- 4
warbling vireo- 1
cedar waxwings- 30 (FOS)
Swainson's thrush- 2 (FOS)
hermit thrush- 1 (FOS)
orange-crowned warbler- 7
common yellowthroat- 6
Wilson's warbler- 6
western tanager- 15

Getting the two *Catharus* thrushes on the same count (at the same spot on
the river actually) was kind of fun. I haven't done that very often.

From farther afield comes news of an intergeneric jay hybrid that I thought
interesting. In Texas, blue jays have been expanding west onto the Edwards
Plateau while intermingling from the south have been green jays. A natural
hybrid was found northeast of San Antonio:

Here's hoping that the numbers and variety of passerine migrants locally
picks up soon.

Best,
John Trochet
