I went out to Hudemann Slough looking for the Red-necked Phalarops and found a flock of them, but what I really got excited about was a field 1/4 a mile north of the slough. At first glance I thought maybe pheasants out in this field with crows, but on closer look realized they were hawks.
Even though there was a tractor mowing the fields, and farm workers tending to the vineyards, whenever I pulled my car over they would fly. I was patient, watching quietly and in the short time I was there I counted 4 Swainsons, a Red-tail Hawk, Northern Harrier, Turkey Vulture and even an American Kestral flew over...pretty exciting! I think this is a juvenile Swainsons?
