Species Information: Western Barn Owl (Tyto alba)
Family: Tytonidae
The male and female Barn Owls look similar in appearance. They have a heart-shaped face with grey-brown wings. Males are generally lighter in color than females, including on their underparts, which are often pure white. Females typically have darker feathers, with dark-brown feathers forming a facial disc, small black spots on their chests, and dark bars on their tails.
Their diet consists primarily of rodents such as voles, mice & shrews. But they will also eat spiders, earthworms, snails, small birds, and even fish. They are efficient hunters, able to pinpoint prey with their acute long-range eyesight and sensitive hearing. They then use their silent flight and long legs to snatch prey even in long grass.
They can be found across a range of habitats except uplands and urban locations. They are also found in rural areas, particularly where there is open pastoral land for them to hunt.

Barn Owls have a screeching call. So much so that they are colloquially known as Demon Owls in some regions.
Western Barn Owl Calls:
Barn Owls nest in the hollows of trees, rocky ledges, as well as in old barns and buildings. They don’t build a nest, they use natural hollows so that eggs don’t roll away. This often includes the previous year’s nest site. They have up to 2 broods each year, with the first clutches being laid in May, though it can be as early as March based on food availability. Each clutch consists of up to 6 eggs, which are incubated for 32 days by the female. Once hatched, the nestlings take roughly 2 months to be fully fledged.2

Goshawks and Common Buzzards are the key predators of Barn Owls.
Barn Owl populations went into a steep decline in the 1950s and 60s, attributed to a loss of habitat and the extensive use of toxic chemicals in the agricultural industry. Further population declines were attributed to habitat loss right up to 1995, leading them to be UK Amber-listed as a threatened species. Since then, populations have increased, mainly due to the erection of nest boxes, leading to a reclassification of the species to green-listed.
