Junco's seen before and Black-chinned Sparrows. County midway between camp & summit of midhills becomes very rocky (large, loose granite outcrops) mixed with large Cincops Juniper. In the washes occurs Chrysostamnes and Artemisia, and some rocky slopes contain Yucca baccata, cactus and Artemesia alone. On these slopes is where the Black-chinned Sparrow was found #. At higher altitudes (about 6000) near the summit we also found the sparrows in a similar habitat. The birds seemed to be travelling in pairs and were difficult to collect. When flushed the birds may fly 500yds away in a direct line or circle about in an equally large diameter. Singing posts were noted to be both high and low, frequently from tops of occasional Pinyons or Junipers, and Artemesia. I found one nest # in Artemesia. One of the parents was less wary than the other but would approach only within 2' of nest when coming there. Song started out high-pitched with about 5 notes nearly on same level of scale & gradually descending, notes getting faster & almost vibratory. Census for today: 24 species, 169 individuals, 8.5 hrs. Ash-throated Flycatcher 4- Western Scat Catcher 8- In trees as well as brush. Even-backed Goldfinch 4- Seen hard near going by camp Warbler (species?) -1- probably Pileated (glance)
