Description: Home range size and habitat utilization of three breeding male Richardson’s Merlins (Falco columbarius richardsonii) in southeastern Montana were studied using radio telemetry. Home ranges of these birds encompassed 13,23, and 28 km2. Each bird traveled up to 9 km from its nest. Each home range encompassed five habitats; sagebrush/grassland, riparian, and Ponderosa Pine (Pinus ponderosa) communities were used significantly (p < 0.05) more, and grasslands and agricultural fields less (p < 0.05), than expected, based on the proportions in the combined home ranges. Four sites regularly used by hunting male Merlins indicated preferences for patchy shrub/grasslands as hunting habitats.
