Abstract

"Home ranges of 49 raccoons (Procyon lotor) from St. Catherines Island, Georgia, each captured at least five times, are compared with home ranges of nine radiotagged raccoons. The mean of final estimates of home range sizes of 35 males (51 SE 68 ha.) was significantly different from that for 14 females (6 SE 10 ha., t = 2.42, p. < 0.05). The limited female trapping success is related to both a higher mean time interval between captures and a higher mean number of captures per station of capture than for males. Home range size seemed to increase with number of captures using both mean convex polygon and mean circular estimates as well as regression analyses. The estimates of home range of a male raccoon captured 103 times changed in shape, location, and size each year in the four-year study period and did not approach the final estimate of 254 ha. asymptotically. The mean yearly radiotracking home range estimate of seven males (65 SE 18 ha.) was not significantly different from that for two females (39 SE 16 ha.). For females, the mean home range based on radiotracking was significantly different from the mean home range based on recaptures (t = 3.86, p < 0.05). Home ranges determined by radiotracking did not always coincide closely with home ranges determined by recaptures for the same animals during the same time periods"--P. [1].
