Pittsboro 1943 June 19 Hayfork Passy, 3200-6262 ft., Trinity Co., Caly. At the top of the mountain there is a Forest Service fire lookout. A cabin at the base of the lookout is occupied (at this time) by an elderly man and his wife, who have apparently lived in the mountainous country of this region for at least 15 or 20 years. There was a wonderful view of the Trinity peaks. On the way up, beginning at 4000 ft., a tabulation was made of the numbers of each species heard or seen for each 500-foot belt. In all 34 (probably 35) species were recorded between 4000 feet and the summit. The most abundant species in the coniferous forest were Dendroica auduboni, D. occidentalis, Vermivora ruficapella and Junco oreganus. In the chaparral area, Cassisella ilacea and Olerholsera chionura were most abundant. Other species noted in the chaparral area were Aporonis kolmei; Vermivora celata, Empidonax wrighti, and Chamaea fasciata (5720 ft.). The tabulation of species mentioned above follows:
