Zusammenfassung:Inconsistencies were found in most experimental designs used in telemetry studies of coyotes (Canis latrans). Methods reported in the literature were assessed relative to their ability to produce reliable estimates of home-range size. Relocations collected sequentially over set blocks of time were superior to those collected sporadically once or twice a day. A four-season division of the year (breeding, 1 Jan-15 Mar; gestation, 16 Mar-30 Apr; pup rearing, 1 May-31 Aug; dispersal, 1 Sep-31 Dec) best represented behavioral changes in coyotes that may affect home-range size. The number of sporadically collected relocations needed to adequately delineate home ranges was tentatively established to be about 100. Four to five 24-hour samples of sequential relocations seemed adequate to delineate home ranges of males and females in the pup-rearing season. Review of existing data indicated that most home-range estimates were derived from data bases too small for valid analysis. Analysis of remaining data indicated no evidence of difference among home ranges of coyotes from four different geographical areas. Future studies should concern delineating patterns of home-range use and correlating these patterns to vegetal, physical, and faunal characteristics of the home-range area.
