LLW81/4 1967 Journal August 12 Cuernavaca, Morelos to 1 mi SE Tamazulapan, Oaxaca, Mexico Drove to Tamazulapan, Oaxaca arriving at 1730. About 1 mi. SE of town a grassy road leads off to right at base of hills. Drove in for 5 mile + parked for the night. Went up onto hillside looking for birds before supper. Dick collected a Black-throated Sparrow. Did not see any Oaxaca Sparrows. Chased Occidenta Thrushes in vain attempt to collect one. Set up camp + skinned the bird which Dick prepared supper. To bed under beautiful, clear sky at 2030. Heard Great Horned Owl call soon after gone to bed. August 13 1 mi SE Tamazulapan to Oaxaca, Oaxaca, Mexico Up at 0545. Had breakfast as it was getting light. Both Dick & I then out to collect. Spent until 1100 hunting in hardleaf + thorny chaparral. Characteristic plants included a holly-type, Arcto- Stephlos sp. + Quercus rugosa + several other oaks. Vegetation averaged 6-8 feet tall with some up to 10 feet. Essentially covered the hillsides. Substrates was rocky + there were scattered blue areas of rock outcrop. Rather than parts of area facilitated walking. Found only one pair of Oaxaca Sparrows & took the 50. 50 yds in either direction along the stream bottom I squashed in adult Rufous-crowned Sparrows. Oaks may have been more pre- dominant when took notosticta, but not much. Possibly the 2 species hold interspecific territories. Dick reported seeing 3 S-terra Sparrows on a hillside above a streamgully. Located a flock of 10+ BL-cued Bushlark + 'schwered' them in.
