Rarities in Yolo County
late 1995 - present
METHODOLGY (what birds are included):
This list includes only species with individual records (as opposed to dotted lines) in the Yolo County Checklist. For birds seen before spring 2004 I use the 1993 edition; for birds seen after spring 2004, I use the 2004 edition.

EXCEPTIONS (not included):
Least Bitterns after 2004
all Western Gulls
Lesser Black-backed Gulls after Jan 2014
Eurasian Collared-Doves after 2005
Grasshopper Sparrows after 2002
Great-tailed Grackles after May 2000

Additional note: Iceland Gull now includes thayeri, kumlieni, and glaucoides. All three have occurred in the county. For posterity, the white-winged individuals resembling nominate glaucoides are listed here.

This Common Ringed Plover was a first for Yolo County and the state of California.
