I spent Wednesday 17 May 2023 (5:30 AM to 5:15 PM) with Christine A Dean looking for birds along part of the south shore of the Salton Sea and at a few select locations in the Imperial Valley. We started the day at the west end of Young Road then drove directly to the IID Wetlands near Niland. After looking at the IID Wetlands we drove the short distance north into Niland. In Niland we birded north along International Avenue, west along 4 th Street and south along Luna Street. From Niland we drove southwest to the Salton Sea National Wildlife Refuge HQ on Pound, Davis, Schrimpf, Garst and Sinclair Roads, stopping to look at the Hunt Club on Pound Road, the east end of Morton Bay and the north end of Garst Road on the way. At the Salton Sea National Wildlife Refuge HQ we looked we looked at the ponds adjacent to Rock Hill, the distant shoreline of the Salton Sea from Rock Hill and around the entrance parking area. We then drove southwestward to Obsidian Butte and along the seawall to the west end of Young Road. From the west end of Young Road we drove southwestward into Unit 1 of the Salton Sea National Wildlife Refuge. From Unit 1 of the Salton Sea National Wildlife Refuge we drove southeastward through Calipatria into Brawley. In Brawley we looked at Riverview Cemetery and Cattle Call Park. From Brawley we drove south along Dogwood Road to near the southeast corner of El Centro. After spending more than two hours near the southeast corner of El Centro I drove west towards San Diego, ending the day at Fig Lagoon. Mostly clear with no wind, and with temperatures ranging from 65 to 105 degrees.

As I was walking up to the front of the house near the southeast corner of El Centro, I caught a quick look at rufous-brown bird fly up from the ground at the water feature and disappear from my view. Knowing that a Brown Thrasher was known present, I advanced hoping I could see the bird. As I approached the bird flew out of the vegetation over the driveway ahead of me and appeared to land in a mulberry tree ahead of me. At that time I was able to see that the bird was thrasher-size with a long tail and rufous-brown on the entire upper-parts. My look at the bird was brief, and I did not see the face or under-parts, but knowing the Brown Thrasher was seen here by Kenneth Z. Kurland this morning, I have no doubt that is what I saw. Unfortunately, we were unable to locate it again. As Christine A. Dean and I were watching birds going to the water feature near the barn on Kenneth Z. Kurlands property near the southeast corner of El Centro, Christine drew my attention to a warbler in the open branches at the lower part of a tree about 35 feet ahead of us. The bird was about the size and shape of a Yellow Warble, but mostly gray, darker above than below. During my short look at the bird, I saw that the auriculars were blackish-gray bordered above and below by white, that there was much yellow on the medium and greater wing-coverts, and a trace of yellow on the crown. As the bird flew into some large dense mesquites I thought that I saw some white near the corners of the tail. The bird was clearly a female, probably a first-year female, Golden-winged Warbler . Unfortunately, despite much looking, Christine and I were never able to see it again. Golden-winged Warbler is previously unrecorded in Imperial County, and a male photographed at the Dos Palmas Preserve in Riverside County on 11 September 2019 (Benson, et al 2021) provides the only other record for the Salton Sink. Late in the day Curtis A. Marantz managed to obtain a poor photo but identifiable photo of this warbler in flight. Guy McCaskie
