San Joaquin and Solano

Woodbridge Ecological Reserve (Isenberg Crane Preserve)

This is one of the most accessible areas to observe large numbers of Sandhill Cranes. From October to March, many fields in this area are flooded and filled with Sandhill Cranes, wintering shorebirds, and waterfowl.

Woodbridge Wilderness Area (formerly Woodbridge Regional Park)

During summer months, you may find Swainson's Hawk, Western Wood­ Pewee, Ash-throated Flycatcher, Northern Rough-winged Swallow, Black-headed Grosbeak, Lazuli Bunting and Bullock's Oriole. Birding this area in winter may turn up Red-breasted Sapsucker, Hutton's Vireo, Red-breasted Nuthatch, Brown Creeper, Winter Wren, and Golden­-crowned Kinglet.

Lodi Lake

Lodi Lake Park is truly one of the premier birding areas in San Joaquin County. This reputation is well deserved as over 200 species (over 50% of the county's total bird list) have been observed within the boundaries of this 125-acre jewel along the Mokelumne River in north Lodi.

Lake Solano Park

This magnet for birds on the Solano-Yolo County line is formed by a small diversion dam on Putah Creek several miles east of Lake Berryessa and the Vaca Mountains, the easternmost ridge of the North Coast Ranges. For best birding, visit the area early in the morning; fall and winter are most productive, due to the arrival of winter visitors.

Robinson Road to Birds Landing

Ferruginous Hawks, Rough-legged Hawks, Northern Harriers, White-tailed Kites and Red-tailed Hawks are quite reliable during the winter, although numbers vary year to year. Bald and Golden Eagles are occasionally found especially around the large power lines also frequented by Prairie Falcons.

Lagoon Valley Park

This park just off of Interstate 80 in Vacaville contains nearly 500 acres. It provides excellent opportunities to find water birds and land birds. The reservoir is always worth checking, and it once produced a Long-tailed Jaeger. The trees can be very good for migrants, and a Northern Waterthrush was found here.
