Abstract:

Data on dispersal, home range, and daily activity patterns were collected during 11 months for 15 coyotes (Canis latrans) radio-collared on the Idaho National Engineering Laboratory Site. Dispersal distances ranged from 0 to 57 km for 10 juveniles. Mean home range with standard error for four adult females was 45.9 ± 1.7 km² by the ellipse method and 29.3 ± 2.4 km² by the modified minimum area method. Home range of one adult male was 133.0 km² and 80.6 km² by the two methods, respectively. When more than 100 relocations were available, the modified minimum area method appeared to estimate home range size more accurately. During the summer, coyotes were most active near dawn and dusk. A general lack of activity was noted from 1100 h to 1500 h MST. Analysis of 15 minute interval fixes obtained over a 24-hour period suggested that some areas within the home range received more intensive use than others, particularly areas around resting points.
