As the name suggests, this species is characterized by its strikingly long ear tufts, which are actually made up of feathers and serve no hearing function. While these owls may not rely on their ear tufts for hunting, they do have specific dietary needs that must be met in order to thrive.

Long-eared owls primarily feed on small mammals such as voles and mice, but will also consume other small creatures including insects, birds, and reptiles when food is scarce. Like many raptors, these owls hunt at night using their keen sense of hearing to locate prey in complete darkness. In addition to having specialized adaptations for nocturnal hunting, long-eared owls also possess unique digestive systems capable of breaking down tough animal parts like bones and fur. Understanding the intricacies of long-eared owl feeding habits is crucial for conservation efforts aimed at protecting this fascinating species.

Long-Eared Owl Description And Habitat

The long-eared owl (Asio otus) is a medium-sized bird of prey that belongs to the family Strigidae. This species has distinctive ear tufts, which are actually feathers, and are used for communication and camouflage purposes rather than hearing. Long-eared owls have yellow eyes with black pupils, pale faces with dark streaks, and brownish-orange plumage covered in white spots. They also possess a wingspan of around 95 cm and can weigh up to 400 grams.

Long-eared owls generally inhabit open woodlands, coniferous or deciduous forests, farmlands, grasslands, marshes, meadows, parks, and urban areas across North America, Europe, Asia, and Africa. These birds prefer nesting in dense trees or shrubs located near fields where they hunt for food. During winter months when temperatures drop below freezing point at night time, these nocturnal hunters become more active as they search for rodents such as voles and mice.

The diet of long-eared owls primarily consists of small mammals including voles, mice, shrews as well as some insects during breeding seasons. They use their keen sense of sight to locate prey from high perches before swooping down silently on them using their sharp talons to capture it. As opportunistic predators who rely heavily on rodent populations in their habitat area; if there is an abundance of prey available then these birds may feed on larger animals like rabbits too.

Long-eared owls are monogamous creatures where both partners share parental duties like incubating eggs and feeding young ones until fledging stage. Females lay between four-six cream-colored eggs which hatch after about thirty days into tiny fluffy chicks dependent solely upon parents’ care for survival. Once fledglings leave nest site they will still be fed by adult pair but gradually learn how to hunt themselves under guidance from parents over next few months.
