Updated September 12, 20261 min readCited sources

The barn owl is a medium-sized, nocturnal bird of prey with a pale, heart-shaped face. It is one of the most widespread owl species and is considered least concern globally.

What it is

The barn owl (Tyto alba, or Tyto furcata in the Americas) belongs to the family Tytonidae. It is recognized by its pale, heart-shaped facial disc, dark eyes, and lack of ear tufts. Plumage is buff, brown, and white, with regional variation.

Behaviour and diet

Barn owls are nocturnal predators that hunt by flying low over open ground. Their diet consists mainly of small mammals such as mice, voles, and rats, making them beneficial in agricultural areas. They roost and nest in natural cavities, barns, towers, and nest boxes.

Distribution and conservation

Barn owls have a broad global range, absent only from Antarctica. They inhabit open habitats like farmland and grasslands. In Canada, they occur mainly in southern British Columbia. The species is listed as least concern, though some local populations have declined.

In short

  • Nocturnal predator of small mammals, especially rodents.
  • Distinctive heart-shaped face and pale plumage.
  • Found on most continents, including parts of Canada.
  • Considered beneficial for rodent control in farming areas.
