Feb 26. Thing I saw at dusk was replaced by a growth of mesquite and some widely-spaced plants similar in growth form to individuals of Adenostoma fasciculatum or some of the Eriodictyon of So. Calif. Spacing was wide, about 20 miles west of Carrizo Springs I found another Horned Owl dead beside the road but well mummified. A mile S of Catarina Dimmit County I saw a dead rattlesnake beside the road. Perhaps 3½ feet long, its diameter may have been increased due to bloating. Rattles had been removed either by human or ants so I left it. In the vicinity of Roma, Starr County, the landscape looked somewhat greener and continued to look as though the tributary Apalacome vegetation was better developed as I went down the valley. at 5:40 pm I arrived in Harlingen after passing through a citrus belt which was devastated by the worst frost in 60 years. The aspect of this agricultural area reminded me of the vicinity of Santa Ana, Orange Co., Calif. After dinner I called on Mr. L. Erby Davis of Harlingen, leading local bird watcher and keen observer of these and the Mexican avifauna. We discussed local bird distribution and he advised that I contact Mr. Luther Goldman concerning camping on the Santa Ana Refuge. Feb 27 San Benito, Cameron Co., Texas. I met Mr. Goldman about 8:30 a.m. and talked with him for 45 minutes about various subjects. He gave me permission to camp on the refuge and to band any birds I could catch. He also talked about local distribution on the refuge.
