Silently gliding through the night sky, the Barn Owl is a figure of elegance and mystery. Beyond its ghostly beauty, this bird is a marvel of evolutionary adaptation.

Today, let’s unravel some captivating facts about the Barn Owl and delve into the unique features that make it a formidable nocturnal predator.

Barn Owl Facts

  1. Widespread Distribution:
    • Barn Owls can be found on every continent except Antarctica, showcasing their adaptability to different habitats.
  2. Silent Hunters:
    • Their specialized feathers muffle the sound of their flight, allowing them to approach prey undetected.
  3. Varied Diet:
    • While rodents are their primary diet, Barn Owls also consume birds, reptiles, and insects.
  4. Frequent Breeders:
    • In regions with abundant food, Barn Owls can raise multiple broods in a year.
  5. Twisted Neck:
    • Like other owls, they can rotate their heads up to 270 degrees, compensating for fixed eye positions.

What do Barn Owls look like?

Barn Owls are easily recognizable with their heart-shaped face and beautiful white plumage. They have long, slender legs and powerful talons for catching prey. The wingspan of a Barn Owl can reach up to four feet, making them efficient and graceful flyers.

Remarkable Adaptations of the Barn Owl:

  1. Facial Disc:
    • The Barn Owl’s heart-shaped face isn’t just for show. This concave structure directs sound waves to their ears, amplifying faint noises made by potential prey.
  2. Asymmetrical Ears:
    • One ear is positioned slightly higher than the other, allowing the owl to pinpoint the exact location of sounds in the vertical plane.
  3. Low-light Vision:
    • Their large eyes gather more light, granting them excellent night vision, essential for spotting prey in dim conditions.
  4. Soft-edged Feathers:
    • The leading edges of their wing feathers have soft fringes, reducing flight noise and making their hunting swoops near-silent.
  5. Strong Talons:
    • Their powerful feet and sharp talons can grip and kill prey instantly, while the rough soles help hold slippery prey.
  6. Regurgitation:
    • Barn Owls swallow their prey whole. Later, they regurgitate indigestible parts, like bones and fur, as pellet-like structures.

What sounds do Barn Owls make?

Barn Owls make distinct sounds that can be quite eerie. They screech and hiss, which can send shivers down your spine if you’re not expecting it. Young owlets and females will also make food begging calls. However, if you hear a hooting sound, it’s more likely to be a Tawny Owl.

How can you tell if a Barn Owl is male or female?

Determining the sex of a Barn Owl can be challenging just by looking at them from a distance. However, a closer inspection might provide some clues.

Females tend to have darker brown feathers around the rim of their facial disc, as well as darker bars on their tail and small black spots on their chest and wings. Males, on the other hand, are generally lighter and have a more pure white underside. Females tend to be slightly heavier than males.

Where are you likely to find Barn Owls?

Barn Owls can be found in a variety of habitats, but they prefer nesting in quiet, open spaces like farmland, grasslands, marshes, and meadows. They can also be found in woodlands and along hedgerows.

What do Barn Owls eat?

Barn Owls primarily feed on small mammals, with the Field Vole being their preferred meal in the UK. They have incredible hunting skills, thanks to their sensitive hearing and the ability to see movement in low light conditions. Barn Owls can consume up to 4 small mammals in a night!

Signs of occupation

If you want to know if Barn Owls have made a home in your area, there are a few signs to look out for. One of the most obvious signs is the presence of their pellets, which are tightly-packed balls of undigested fur and bones that they regurgitate. These can often be found around roosting and nesting sites. Other signs include droppings, feathers, and the distinctive calls of the owls.


Barn Owls have several adaptations that make them highly specialized hunters. They have incredibly sensitive hearing, which allows them to locate prey in complete darkness. Their facial disc acts like a satellite dish, directing sound waves towards their ears to pinpoint the exact location of their prey. They also have soft feathers that allow for silent flight, giving them a stealth advantage when hunting.

Hunting and feeding

When hunting, Barn Owls use a combination of their sharp talons and powerful beak to catch and kill their prey. They can snatch small mammals, such as mice and voles, right off the ground with incredible precision. After catching their prey, Barn Owls swallow it whole and later regurgitate the indigestible parts in the form of pellets.

Home range

Barn Owls have a relatively small home range, which can vary depending on the availability of food and suitable nesting sites. On average, their home range can span between 25 and 100 acres. However, during the breeding season, they may establish territories of about 5 to 15 acres around their nest sites.

Nesting – Spring

Spring is the time when Barn Owls start nesting. They typically choose secluded locations like barns, old buildings, tree cavities, and cliffs to build their nests. The female lays her eggs in a shallow depression lined with her own feathers. After an incubation period of approximately 30 days, the owlets hatch, and the parents work together to feed and care for them.

Barn Owl Life Cycle

Owlets – Summer

During the summer months, Barn Owl parents are busy raising their owlets. The owlets are born with a layer of white down feathers, which gradually gets replaced by their adult feathers. As they grow, they become more independent and start venturing out of the nest.

Dispersal of young

Once the owlets reach a certain age, they leave the nest in search of their own territories. This is known as dispersal. The young owls may travel several kilometers away from their birthplace to find suitable nesting and hunting grounds.

Winter – survival

Surviving the winter can be challenging for Barn Owls, especially during periods of extreme weather and food scarcity. Some individuals may migrate to more hospitable areas, while others may rely on finding sheltered roosting sites and altering their hunting strategies.

Life expectancy

The average lifespan of a Barn Owl is around 2 to 3 years in the wild. However, some individuals have been known to live up to 10 years or more. Factors such as predation, habitat loss, and starvation can significantly impact the life expectancy of Barn Owls.

Barn Owl Distribution in UK

The population of Barn Owls in the UK is estimated to be around 5,000 to 8,000 breeding pairs. However, the population has experienced significant declines in recent years due to habitat loss, agricultural intensification, and the use of rodenticides.

Barn Owls can be found throughout the UK, with the highest populations in southern England and Wales. They prefer open habitats with access to suitable nesting and hunting sites.

Historically, Barn Owls were more widespread and abundant across the UK. However, changes in land use, intensified agriculture, and loss of traditional nesting sites have led to a decline in their numbers.

How to encourage wild Barn Owls

There are several ways individuals can contribute to the conservation of Barn Owls. Creating suitable habitats by providing nestboxes, preserving rough grassland areas, and avoiding the use of harmful chemicals can all help encourage Barn Owls to thrive.

Barn Owls and the law

Barn Owls are protected under various laws and regulations in the UK. It is illegal to disturb their nesting sites, intentionally kill or harm them, or possess them without the necessary licenses or permits.
