Central Valley birding – go for the goose!
Editor’s note: We are nearing the end of peak winter birding season in the Central Valley. If you haven’t been there, now is the time! Golden Gate Bird Alliance board member David Anderson offers some tips and routes.

The sky filled suddenly with a blizzard of snow geese, lifting in waves near and far — ten thousand or more. A thousand undulated in the distance, winging high; a few thousand rose then settled back close by; several thousand more circled restlessly.
For a while, the horizon filled with their movements, alternating bright flashes of white as they turned in the sun. Then, the various groups landed or headed away to work (foraging the nearby fields). A cacophony of noise – almost hurting our ears – filled the air with the geese. Ears ringing, eyes wide, I laughed in pure joy. The host of wildlife filling the bright, blue sky was a wonder to behold, a scene of nature’s glory.
Our viewing platform was in the midst of the Sacramento National Wildlife Refuge, part of a system stretching the length of the Central Valley from Redding to Bakersfield. Thirty refuges provide nearly 400,000 acres of wildlife habitat. California wildlife management areas add almost half a million acres more. The two systems give protection to tremendous numbers of migratory birds coming here for the winter, as well as numerous other wildlife species. These lands offer incredible viewing, especially the areas between Willows and Los Banos.

The U.S. Fish and Wildlife Service last year reported 48.6 million ducks in the U.S. and Canada, the most recorded in the 57 years of surveys! Clearly the breeding conditions were optimal. The estimate was that 5 million ducks would winter in the wetlands of the Central Valley, along with record numbers of geese. A mid-winter survey shows about 4 million ducks and one and a quarter million geese. That’s a lot of feathers out there.
We’re reaping the rewards with incredible viewing opportunities, enhanced by long stretches of clear, sunny weather. Snow Geese, Ross’s Geese, Canada Geese, and White-fronted Geese all appear in big numbers. Northern Pintails, American Wigeons, Northern Shovelers, and Green-winged Teal are in even larger numbers.

My favorite birding route from the Bay Area to the Central Valley is I-80 heading east past Vacaville, then I-505 across to I-5 near Dunnigan. …
