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 eastern-most 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.
