Cosumnes & Isenberg Crane Reserves (Central Valley, California)

On a chilly and rainy Friday, Sarah & I headed east to the Central Valley to see what was a’wing at Cosumnes River Reserve and the Isenberg Crane Reserve, two locations I’ve heard much about, but had not previously birded. The year’s end approaching, I wanted to add a few Central Valley specialties to my 2007 list. Eagles of both the Bald and Golden variety, Cranes, Swans, and several Geese occur in this area that rarely, if ever, are found in the immediate SF Bay Area.

Hiking & birding around Marin Headlands

Sarah & I had a lovely pair of mini-hikes on Dec 16 in the Marin Headlands, ahead of an incoming storm.


Tennessee Valley Trail

Our first hike was to Tennessee Valley, a lovely short hike that we hadn’t done in over a year, despite the trailhead being only a 15-minute drive over the Golden Gate. Brewer’s Blackbirds and Golden-crowned Sparrows foraged in the parking lot, but it was otherwise pretty quiet. The first quarter-mile of the trail was rather blustery, but things calmed down once we descended into the valley proper.

EA 115 – Field Ornithology – Class VI

Last week’s class focused on Dowitchers, two devlishly-difficult birds to tell apart, although Dowitchers aren’t too difficult to tell from other shorebirds.

We first talked about Flood & Waverly, an area east of Stockton in California’s Central Valley that is known for having good birds. A classmate recently saw a Short-eared Owl, Ferruginous Hawk, Rough-legged Hawk, American Kestrel, Red-tailed Hawk, Bald Eagle, and Golden Eagle in an afternoon (must’ve been nice!). Other areas of high raptor concentration include the Altamont Pass region (famous locally for its windmill farms, which are killing Golden Eagles), Grizzly Island, and Robinson Road in eastern Solano County, which is also a good place for Mountain Plovers.

We picked up on pg. 188 of the National Geographic Field Guide to North American Birds.

Sutro Baths and Heights birding (SF)

Yesterday was the final field trip of the fall semester of Joe Morlan’s Field Ornithology classes, and despite some chilly-for-California weather, it wound up being a great outing.
