Species Profile

# Short-eared Owl (Asio flammeus) The Short-eared Owl is a medium-sized raptor measuring 34-42 cm in length with distinctive yellow eyes and small ear tufts that are rarely visible. Its mottled brown and buff plumage provides excellent camouflage in grassland environments. Unlike most owls, this species is primarily diurnal and crepuscular, often seen hunting during daylight hours with a characteristic low, coursing flight pattern. As a specialist predator of small mammals, particularly voles and mice, it plays a crucial role in controlling rodent populations across its range. This owl demonstrates remarkable global distribution, inhabiting grasslands, prairies, agricultural areas, and open moorlands across six continents. It breeds throughout much of North America, northern Europe, and Asia, with populations also found in South America, parts of Africa, and various oceanic islands. The species shows nomadic tendencies, with populations moving in response to prey availability. Despite its extensive range, the Short-eared Owl faces significant pressures from habitat loss due to agricultural intensification and grassland conversion. The species has experienced substantial declines in many regions, particularly in Europe and North America, where traditional farming practices that maintained suitable habitat have largely disappeared. Climate change may also affect prey cycles and breeding success. Conservation efforts focus primarily on habitat management and protection of remaining grassland ecosystems. Some countries have implemented agri-environmental schemes encouraging owl-friendly farming practices, while protected areas maintain crucial breeding and wintering habitats. The current outlook remains concerning, with continued population declines reported across much of the species' range, though comprehensive population monitoring remains limited in many regions.

Short-eared Owls are declining primarily due to widespread habitat loss from agricultural intensification and grassland conversion, which eliminates the open grasslands and prairies they depend on for hunting small mammals. Climate change is altering prey availability and breeding success, while collisions with vehicles and wind turbines cause direct mortality across their range.
