As part of a larger study, we investigated the intensity and duration of association between 2 adult male coyotes (Canis latrans) in an agrarian landscape in west-central Indiana. Home-range size and overlap and the intensity of association varied with time. Home-range sizes averaged 7.9 ± 1.1 (SE) and 11.8 ± 0.9 km2, and spatial overlap was substantial. Activity patterns and habitat preferences were similar for the coyotes whether together or apart, and there was no evidence of temporal or spatial avoidance. The 2 males were together most frequently during the pup-rearing and dispersal seasons, suggesting provisioning of pups and vigilance at diurnal resting sites as possible mechanisms for the dyad formation.
