I spent part of Saturday 15 April 2023 (6:30 AM to 3:00 PM) looking for birds along part of the south shore of the Salton Sea and at a few select locations in the Imperial Valley. I started the day at Fig Lagoon, then drove northward into Brawley, stopping at the intersection of Carter and Fites Roads on the way. In Brawley I looked at the hummingbird feeders on Willard Avenue, then at Cattle Call Park and briefly in Riverview Cemetery. From Brawley I drove northward to the west end of Young Road. From the west end of Young Road I birded along the seawall to Obsidian Butte, then drove eastward to the Salton Sea National Wildlife Refuge HQ. At the Salton Sea National Wildlife Refuge HQ I only looked around the entrance parking area. I then drove eastward on Sinclair Road to Highway 111, then south through Calipatria into Brawley, stopping to look at Wiest Lake on the way. From Brawley I drove south to Interstate Highway 8, stopping at Fudge Reservoir and the flooded area adjacent to Neckel Road on the way, then west to San Diego, stopping to look at the Rio Bend Golf Course, Sunbeam Lake and Fig Lagoon on the way. Clear with no wind, and with temperatures ranging from 55 to 85 degrees.
