Steve Hampton's on-line guide to

birding in
Yolo County, CA
because all birds are more beautiful when seen in Yolo County

There's not much original habitat left around here-- all ag fields, channelized rivers, and a whole lot of non-native vegetation. Four of the historically prominant riparian breeders (Yellow-billed Cuckoo, Willow Flycatcher, Bell's Vireo, Yellow Warbler) are extirpated or only pass through as migrants. And finding rarities can be like getting water from rock. But there are --and deservedly so-- quite a few habitat restoration projects, some very large, that provide great birding opportunities.

Local specialties? Yeah, we got a few: lots of Swainson's Hawks in summer, plenty of Yellow-billed Magpies, Tricolored Blackbirds and Ross' Geese if you do some searching, good spots for Common Poorwill, coastal Sage Sparrow, and Lesser Nighthawks, and some of the best shorebirding in North America when water levels are right.

I hope this page can answer some your questions.

A mandatory Yolo County birding resource is the Checklist of Birds in Yolo County. The latest revised 2004 edition is available at Yolo Audubon Society meetings. It has every species' status by month with bar graphs, as well as some information on places to go birding in Yolo County.
