9 March 2. 4 miles SE Rio Grande City, Starr Co., Texas Turkey Vulture, Harris Hawk, myrtle warbler (few) Cottonail. The only reptile seen was a large black snake, perhaps 42" long. After 10:00, bird hunting was poor and I had no opportunity to take any Green Jays. Notably absent was the Golden-fronted Woodpecker – few ebony trees in area. I drove into the city and had lunch, after which I drove north to a city dump 1/2 mi NE Rio Grande City. I walked over and around trash heaps on sandy soil and pebbly slopes among the mesquite trees and xeric shrubs from 12:10 – 12:40. I saw no reptiles although I took many occasions to turn over boards, cardboard boxes etc: Mockingbird the only bird seen. From 12:50 – 1:05 I walked along the edge of a clearing in the mesquite N of the tracks and NE of Ringgold Barracks. Again no activity in this supposed habitat of Liotophrys reticulatus. The original cover seems to have been mesquite thicket with Adolphia (?), feancake Opuntia, a lead-pencil cactus, and some other shrubs. In some places the undergrowth seems to be lacking perhaps due to clearing. I found no extensive grassy country along the way. I returned to the Refuge at 3:15 pm. (see acct of Parus atricristatus) March 3. Santa Ana Wildlife Refuge, 7 mi S Alamo, Hidalgo Co., Texas. Overcast, calm morning. I noted a Yellowthroat (?) singing in weedy growth in dried up lake E of headgate. The song I recorded as "Râdelsey Raydelsey" had the accent on the first syllable.
