There are other good spots but they are on private property. Roads that are not marked are generally okay. Most growers and farmworkers are friendly to folks driving the back roads through ag land, but know that environmentalists are not high on most people's popularity list in this conservative, rural county. I always ask for permission if I am going to be going too far off the beaten track, particularly on the Boswell holding in the southeast part of the County. This part of the county is the best for Turkey Vultures and Ravens, so keep your eye out overhead.
Turkey Vultures are common overhead.
Double-crested Cormorant is around, and in spring, summer and fall it is tough to miss Cliff Swallow. Check the huge metal high tension towers right at Kettleman City for Turkey Vultures and Red-tailed Hawks. If you are really lucky, you'll pick up Starling at this scenic spot, too. It is decent for Black Tern and Bonapartes Gull, occasionally has Yellow-headed Blackbird, and is the best spot accessible to the public for shorebirds such as Lesser Yellowlegs, Western Sandpiper and Dunlin. The ponds further north are generally less productive as they are deeper, but grebes and Ruddy Ducks abound in season.
