R.A. Kelly 1984 Journal 7 At Pierson's, 629 Miner Rd, Orinda, Contra Costa Co., California May 16 to May 19 Set up 45 pairs of Longworths with Ed Heke and Ann Brook on the grassy hill opposite Pierson's. 5 x 9 stations on grid. Testing for trap responsiveness of Microtus californicus ♂>> and ♀♀ to clean and dirty (♂ or ♀ respectively) trap bedding. Each station contained a clean trap and alternate lines of 9 were either ♂ (2 lines) or ♀ (3). Ann & I returned each morning (17, 18, & 19) to check for captures - sexed, weighed and also checked for (or gave) toe clips (see across). Vole catches were fairly low only about 2 or 3 dozen animals for the 3 days and some of those were recaptures. We also got a number (~6) Rutherodentus and 3 alligator lizards. Both Ann and I got plenty of practice at handling and toe-clipping voles. But I still managed to get a nasty bite from the last animal I handled.
