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.  …

Our years of advocacy on behalf of raptors at the Altamont Pass wind farm are paying off — with a dramatic reduction in bird mortality there.

Deaths of four key raptor species from Altamont wind turbines dropped by an estimated 50 percent between 2005 and 2010, according to the independent scientific review committee charged with monitoring bird mortality there.

The estimated number of Golden Eagles killed by turbines each year fell from 58 to 33, Burrowing Owls from 543 to 233, American Kestrels from 415 to 268, and Red-tailed Hawks from 196 to 85, according to a report accepted last month by the Scientific Review Committee of the Alameda County Altamont Pass Wind Resource Area (APWRA).

These figures are rough estimates: It’s exceedingly difficult to track exact numbers of bird deaths on the sprawling Altamont Pass. And while the data indicate a decline in risks to birds, we know bird injuries and deaths are likely to always result from wind turbine operations.

But the findings are still very good news. They show that with careful siting and design, it’s possible to significantly reduce the risk to birds from wind turbines.

The results also show the positive impact that Audubon activists can have in speaking up and pressuring wind companies to protect birds.

The roots of this good-news story go back more than a decade, to when we at Golden Gate Bird Alliance joined other Bay Area chapters including Santa Clara Valley, Ohlone, Marin and Mt. Diablo Audubon to advocate for birds and other wildlife at the Altamont Pass. (Other conservation groups such as the Center for Biological Diversity have also stood up for birds at Altamont.)

The oldest wind farm in the country, Altamont had about 5,000 turbines in the area bordering Alameda and Contra Costa counties. Researchers estimated that thousands of birds – some migrants, some year-round residents – were dying from collisions with wind towers and blades.

In 2004, we and our partners sued Alameda County for reissuing wind turbine permits in the APWRA without conducting any environmental review. The settlement of our suit required a 50 percent reduction in bird mortality by 2009, removal of certain high-risk turbines, and development of a comprehensive conservation plan.

In 2010, when it became clear that the 50 percent reduction had not been reached, we pursued further negotiations with NextEra Inc.,…

Strawberry Canyon has it all – a vigorous year-round stream, lush riparian vegetation that  follows the stream, and surrounding hillsides with native coastal chaparral and open grasslands.

The U.C. Botanical Garden, located on 36 acres at the upper end of the canyon, features not only the stream and the riparian habitat but extensive collections of plants from around the world.

The Garden, with its shady glens and open hillsides, has attracted birders almost from the time it moved up into the Canyon in 1923 from its original home at the west end of the Berkeley Campus. Its publication, “Birds of the UC Botanical Garden,” lists 100 species, many of which are year-round residents.  Others are seasonal residents, and some are casual visitors.

Every season offers its pleasures.  In the winter, the garden is full of wintering sparrows along with Hermit Thrushes, Ruby-crowned Kinglets, and gaudy Red-breasted Sapsuckers.  Most winters, Varied Thrushes can be heard and sometimes seen in the denser areas of the Garden.

In the spring, the canyon and the garden resound with glorious songs from breeding singers like Black-headed Grosbeaks, Warbling Vireos, and the Pacific Wren.  Partial songs of Fox Sparrows and Hermit Thrushes can be heard briefly before they leave for their summer haunts.

For at least the last decade, the Garden has had its own Red-tailed Hawk – an unusual partial leucistic bird with a white mantel and a pale breast.  Seen year-round, it is easily identifiable as a distinct individual.  Most years, it is paired with a normal colored morph.

Along with welcoming a steady stream of birding visitors, many with cameras in addition to binoculars, the Garden offers quarterly Saturday morning walks co-led by Chris Carmichael, associate director of horticulture and collections, himself an avid birder.  Golden Gate Bird Alliance member Phila Rogers was asked to step in as a co-leader when expert birder Denis Wolff moved to Oregon.

Even if birding is slow, Chris, with his deep knowledge of plants, has wonderful stories to tell, rich with examples of how the local native birds have adapted to exotic plants.…

If you’ve only seen Nome as the snow-covered finish line for the Iditarod, well — as Madeline Kahn sang, “You’d be surprised…”

At about 9 p.m. on a June evening, we stepped down from our third aircraft of the day into the pleasantly brisk Nome twilight. Green grass bordered the airfield, interrupted by small patches of snow. A short drive around the city and harbor started our trip list with Red-Throated Loon, Red-Necked Grebe, Long-Tailed Jaeger, Slaty-Backed Gull, Common Redpoll, Red-Necked Phalarope, and — in someone’s backyard — a few musk oxen. Our modest motel was located at the Iditarod finish line on the shore of the Norton Sound, which was smooth as glass.

We were in Nome on a birding trip sponsored by Golden Gate Bird Alliance. Our guide, Rich Cimino of Yellowbilled Tours, uses the extended daylight of “the land of the midnight sun” to provide an intense three-day birding experience. The birds are active both day and “night,” and so were we. We saw about 90 species and got 15 life birds.

For a couple of Bay Area birders like ourselves who are used to seeing shorebirds on the shore, it seemed odd to see shorebirds nesting well inland in shrubs (Western Sandpiper) or on an airstrip (Ruddy Turnstone).

Nome is a frontier town built to survive the winter: It’s a mere 100 miles south of the Arctic Circle. Structures have few windows — they’re inefficient in the cold — and the tallest building is the new four-story hospital.

Because you must fly or barge everything in or out of Nome (there are no roads connecting to the outside world), the environmentalist comment that you never really throw anything away is vividly illustrated here. Industrial trash — trucks, buildings, machinery — stays where it stopped. And with a year-round population of only 3,700, it’s not hard to get out into nature. The “suburbs” are a 15-minute drive from the main street of the town.

On Day 1 we drove southeast along Council Road in a warm, comfy pickup. The drive started along the beach and lagoons—finding Brant and Cackling Goose, Common Eider and Harlequin Duck, Lapland Longspur, Black-Legged Kittiwakes, Arctic Tern, Red-Throated Loon, and Yellow Wagtail.…
