The activity patterns of radio-collared black bears were monitored during 1996-1998 at two study areas in the North Cascades of Washington, USA. Compositional analysis of activity patterns showed that black bears were not equally active across time periods and that they exhibited crepuscular activity patterns regardless of sex, season, or study area. The lowest level of activity consistently occurred during the 0201-0400 PST time period. In general, females were most active during the morning and males during the evening. The results of this study suggest that diurnal telemetry data would adequately describe black bear resource use.
