Physical Characteristics

The barn owl is characterized by its distinctive white, heart-shaped facial disc and dark, soulful eyes. Its body features a golden-brown plumage with subtle grey and white markings.

• Females typically display darker and more marked plumage compared to males, showcasing sexual dimorphism.
• During the breeding season, the owl's plumage may appear more vibrant.

Juveniles have a fluffier appearance with downy feathers. The barn owl's silent flight and distinct screeching call make it easy to identify in the field, especially at dusk and dawn.

Habitat and Distribution

Barn owls have a vast geographic range, inhabiting countries worldwide except for Antarctica. They prefer open habitats such as grasslands, agricultural fields, and mixed woodland areas.

• Typically non-migratory, barn owls may roam locally depending on food availability.
• Maps showing range distribution often highlight areas with high populations, such as North America, Europe, and Australia.

They adapt well to human-modified environments, often nesting in barns and abandoned buildings.

Behavior and Ecology

Barn owls are primarily nocturnal, engaging in solitary hunting during the night.

• They exhibit social behavior mainly during breeding seasons.
• Their vocalizations include a distinctive screech, unlike other owls that hoot.

The flight of a barn owl is almost silent, due to specialized feather structures. Territory and home range vary based on prey availability, and barn owls have complex interactions with other species, often being preyed upon by larger raptors.

Seasonal Behavior Table

Season	Behavior & Activities
Spring	Nesting and breeding, increased vocalizations
Summer	Raising chicks, intensified hunting
Autumn	Dispersing juveniles, expanding territories
Winter	Maintaining territory, lower activity levels

Diet and Feeding

The primary diet of barn owls includes small mammals, particularly rodents such as mice and voles.

• They use skilled hunting techniques, relying on acute hearing to locate prey.
• Their diet may vary seasonally, with an increase in birds and insects during warmer months.

Barn owls demonstrate unique feeding behaviors, often regurgitating pellets containing undigested bones and fur.

Reproduction and Lifecycle

Barn owls typically breed in the spring, engaging in fascinating courtship displays that include vocalizations and aerial maneuvers.

• Nests are often in tree cavities, barns, or abandoned structures.
• Eggs are white and number 4-6 per clutch.

The incubation period lasts around 30-34 days, with chicks developing rapidly under parental care until fledging at about 8-10 weeks.

Conservation and Human Relations

Currently listed under the conservation status of Least Concern, barn owls face threats from habitat loss, pesticide use, and vehicle collisions.

• Conservation efforts include monitoring populations and preserving habitats.
• Barn owls interact positively with humans, helping to control agricultural pests.

Tips for backyard bird watching include creating owl-friendly environments and avoiding disturbances.
