Patelka 1946 Oct. 16 El Batel, 70 km. NE Mazatlan, 5100 feet, Sinaloa. Hunted this morning around first high point south of the pass. Birds not numerous, one reason among other probable ones being the fact that the sky cleared early and activity subsided in mid-morning. Collected a wren =Trogodytes brunneicollis (Thryothorus?), a small buffy flycatcher =Mitophanes (Empidonax?), a white-treated hutchat, a woodhewer, an Aimophila spanow (probably ruficeps), and a male Mearn's quail. The last mentioned was with a female and a group of at least 3 or 4 young more than half grown, and was taken when he came back toward me, feigning injury, possibly in response to my squeaking. All hunting was done within oak-pine woodland of varying degrees of openness. The high point mentioned above provided a spectacular view to the east and around to the coast. To the east two major ranges could be seen. There were many exposed vertical rock faces, and the general ruggedness of the landscape exceeded anything I had seen earlier. Oct. 17 Stayed in camp to finish skinning specimens I obtained yesterday and to prepare skins of the remaining pairs collected by Leopold and Alberto. The Spizella prepared under today's date was collected by Leopold.
