LLW01F 1963 Journal July 4 Silver City Grant Co., New Mexico up at 0800 - had breakfast & then into field. drove past Bear Mt. Ranch to area of oak, juniper, pines + ceanothus. Ground was bare 50%+. Rufous-crowned Sparrows, Black-chinned Sparrows + Rufous-sided Towhees were common & singing. Virginia Warblers appeared in pairs while Bush-tits were in flocks. These species were all on the mixed ceanothus, juniper, oak hillside. Solitary Vireos were singing occasionally from the conifer groves. I tried to record Rufous-crowns about 0800. Except for occasional bouts of 2 or 3 songs they were completely quiet. After John returned to car with his birds we drove 2-3 miles farther & found 2 or 4 singing Rufous-crowns. I recorded two of them - one from each side of road. Meanwhile John found a Bush-tit flock & tried to secure another black-eared form like one he had taken earlier in the morning. This area was more open grassy hillside with scattered oaks + junipers. One mile further along the road we stopped in an overgrazed area with 35-50% cover of bear grass & junipers + oaks. Found one male singing Cassin's Sparrow. It gave several flight songs - fly up in arc → song started just
