Patelka 1946 Journal Sept. 30 Left Berkeley with G. S. Leopold and W. C. Russell for Magatlan, Lindoa, travelling by M.V.Z. Dodge truck. Followed route south through San Joaquin Valley to Bakersfield, thence over Tejon Pass, thence eastward, between the southernmost Sierra Nevada and the San Gabriel-San Bernardino ranges, to the Barstow-Victorville-San Bernardino Road, thence southward to San Bernardino and eastward to Indio, where we spent the night. Open, more or less flat region between the Sierra Nevada and the San Gabriel Mts. East of Tejon Pass is farmed to a large extent, but in certain areas, abruptly outlined, there are extensive stands of Joshua trees and junipers. The breeding avifauna of these areas would merit investigation. Oct. 1 Proceeded, through Blythe on the Colorado River, Salome and Phoenix, thence southward to Tucson where we spent the night. Visited Sheffer's "zoo" at Salome; it is made up chiefly of a extensive variety of psittaciforms - a really impressive collec- tion. In addition, the collection includes a variety of ducks, caracaras, Crax, ravens, owls, etc. There was one Aphelocoma that appeared to have come from the San Joaquin Valley. Oct. 2 Proceeded from Tucson southward to Nogales, where we spent between 2 and 3 hours getting across the border. Then continued southward to Hermosillo where we spent the night. Road of rough gravel for the most part and broken frequently by small
