I spent Sunday 2 April 2023 (6:30 AM to 4:15 PM) looking for birds along part of the 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 Sheldon Reservoir 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 northwestward to Unit 1 of the Salton Sea National Wildlife Refuge. After looking at Unit 1 of the Salton Sea National Wildlife Refuge, I drove northeastward to the west end of Young Road. From the west end of Young Road I birded along the seawall to Obsidian Butte, then moved eastward to the Salton Sea National Wildlife Refuge HQ. At the Salton Sea National Wildlife Refuge HQ I looked at the ponds adjacent to Rock Hill, the shoreline of the Salton Sea from Rock Hill and around the entrance parking area. I then drove eastward to Highway 111, then south through Calipatria and Brawley to the flooded area adjacent to Neckel Road and Evergreen Cemetery. I then spent some time near the southeast corner of El Centro. From there I drove west to San Diego, stopping to look at the Rio Bend Golfcourse, Sunbeam Lake and Fig Lagoon on the way. Mostly clear with some wind in the late afternoon, and with temperatures ranging from 55 to 85 degrees.
