Subject: [CVBirds] changing climate and overwintering migrants
A sobering fact about our changing climate: in December 2017 in Yolo County
there were 3 species of orioles and 8 species of warblers:

Orchard Oriole (1)
Hooded Oriole (pair in north Davis)
Bullock's Oriole (1)
Yellow-rumped Warbler (expected)
Orange-cr Warbler (expected)
Common Yellowthroat (expected)
Black-thr Gray Warbler (at least 8 individuals)
Townsend's Warbler (at least 3 individuals)
Wilson's Warbler (1)
Yellow Warbler (1)
Palm Warbler (1)
also, there were 2 Cassin's Vireos and several Western Tanagers. Blue-gray
Gnatcatchers are also over-wintering in many new locations the last two
years.

Compared to 10, or even 3, years ago, this is astounding.

Also noteworthy is a seeming dearth of Cedar Waxwings, which are presumably
staying further north.
