Grigsby, Everett M.,2013-08-162013-08-161980http://hdl.handle.net/11244/4720To determine the seasonal movements, maternity sites, hibernacula and philopatry of the gray bat, Myotis grisescens, in the southwest portion of the Ozark Plateau, 6858 gray bats were banded at seven locations in Missouri and Oklahoma. Thirteen per cent of these bats were recovered at 14 locations in Arkansas, Missouri and Oklahoma, from 1968 through 1978. There were several multiple recaptures and roundtrip recoveries between maternity and hibernating caves. The gray bats arrived at their summer feeding grounds in northeastern Oklahoma in late March and early April. In May they moved into four maternity caves, where parturition began in early June. The young were volant by mid-July and the gray bats began returning to their hibernacula in early September. The gray bats from northeastern Oklahoma flew 130 km and 194 km to their respective hibernacula in Missouri and Arkansas. The individual bats frequented only one hibernaculum, thus demonstrating site fidelity or philopatry to their wintering cave.xi, 96 leaves :Biology, Ecology.Thesis
