Banks, RC. 1955 3♂2♀ Peromyscus truei, and 6♂3♀ Reithrodontomys megaleotis, and 1 unidentified mouse (Peromyscus maniculatus?) Also caught were 2 mice, (Ontimus torosus) , and 1 Fox Sparrow, Passerella iliaca. I put up the bird, 1 Reithrodontomys ♂, the Sorex, 1♀+3♂ truei. John did the Perognathus, the Microtus and 1♂ truei. As usual, all Reithrodontomys were by the thistles, all truei by the Baccharis. The Perognathus + Mice unidentified were also by the thistles (they joined a grassy strip), the rest by the Baccharis ( Coyote Brush, Chaparral Broom) Sun. A.M. we had another unusual catch. It included 2♂ Spotted Jonkee (Pipilo maculata), 1 Fox (Passerinatus) Sparrow, 1 Plain Fieldmouse?, 1 meowt, 1♂ Peromyscus truei, 1♂ Mice musculus, 1♂ Microtus californicus, 3♂2♀ Reithrodontomys megaleotis. I did the truei + the Microtus, John the Mice. The Reithrodontomys were all pretty well chewed up or beat up. These mice specials are too large for Reithrodontomys. They are usually (at least often) caught by the tail or hind feet and live to chew their tails or feet. If they are killed, something else usually chews them. Why? they be cannibalistic? See specie accounts for data on mice putups as skins. Have birds to J Schnell.
