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.
