Decline on farmland

Historically, the barn owl was Britain’s most common owl species, but today only one farm in about 75 can boast a barn owl nest.

Screeching sound

Barn owls screech, not hoot (that’s tawny owls). To hear the cry of the barn owl, and other British owls, visit the Barn Owl Trust website.

4

Silent night

The barn owl can fly almost silently. This enables it to hear the slightest sounds made by its rodent prey hidden in deep vegetation while it’s flying up to three metres overhead.

5

Directing sound

The barn owl’s heart-shaped face collects sound in the same way as human ears. Its hearing is the most sensitive of any creature tested.

6

Sharing territory

Barn owls are non-territorial. Adults live in overlapping home ranges, each one covering approximately 5,000 hectares. That’s a staggering 12,500 acres or 7,100 football pitches!

7

Sustenance from siblings

It’s not uncommon for barn owl chicks in the nest to feed each other. This behaviour is incredibly rare in birds.

8

On the menu

In order to live and breed, a pair of barn owls needs to eat around 5,000 prey items a year. These are mainly field voles, wood mice, and common shrews.

9

Once a year

Though barn owls are capable of producing three broods of five to seven young each year, most breed only once and produce, on average, only two and a half young. Twenty-nine per cent of nests produce no young at all.

10

Deadly poison

Ninety one per cent of barn owls post-mortemed were found to contain rat poison. Some owls die as a direct result of consuming rodenticides, but most contain sub-lethal doses. The effects of this remain unknown.

11

Road kill

In a typical year, around 3,000 juvenile barn owls are killed on Britain’s motorways, dual carriageways and other trunk roads. That’s about a third of all the young that fledge.

How to help

Everyone can help barn owls. Leave a patch of rough grassland to grow wild thus creating habitat for voles, erect a super-safe deep nest box, volunteer for your local barn owl group, switch to non-toxic rodent control and support charities working to conserve the barn owl.

The Barn Owl Trust (BOT) is a small grassroots charity, and a great source of high-quality information about the species.
