Hoffmeister 1942 Itinerary May 15 Walker Cr., 4 mi. SW Olancha, 5700 ft., Inyo Co., Calif. to Olancha. At Coso Junction, a filling station operator gave of 2 birds, the description us a description fitting of Egrets (probably American), that he said were present along the highway following a hard storm a week or two before our arrival. We turned west about 1 mile south of Olancha and continued up towards the base of the Sierra Nevada, camping 1/5 mi. beyond the junction of Fall and Walker creeks, and along the latter. Along Walker Creek, there are 2 kinds of oaks, Quercus dumosa and Quercus ____________ which are the dominant trees. About [illegible] beyond the junction of the two creeks, the first pignon is encountered. These pignons are not abundant and widely spaced. On the flat towards Owens Valley (east of Walker Creek), the dominant shrub is Artemesia with abundant large lupines. I set out 75 "museum special" traps along the flat east of Walker Creek. Saw Citellus (probably beecheyi), Sciutamus minimus. May 16 Caught 31 mammals: 2 Neithrodontomys megalotis (?; ?), 10 Peromyscus maniculatus (??, 2 ?, unsexed), and 19 Peromyscus boylii (9?, 10 ?). Shot 1 chipmunk and saw numerous others. In returning from my trap line, I saw a Belted Kingfisher (Megacere aleyon) fly down Walker Creek, alight for less than 1 minute on a 35 foot tree, and then move on down stream. Walker Cr. now has only a small amount of water in it, being only about 2 1/2 ft. wide, on the average, and 6 inches or less deep. I saw 2 Bush-tits (Psaltriparus minimus) and heard at least 2 more. They were all in oaks growing along the Creek. I do not know whether they were paired or in larger flocks (of not more than 3 or 4). When I got close enough to the
