Tree hollows are natural cavities within trees that can provide suitable nesting sites for Barn Owls. These hollows offer the owls a safe and protected space to lay their eggs and raise their young. However, tree hollows can sometimes be limited in availability, depending on the location.

Nestboxes are man-made structures specifically designed for birds to nest in. Barn Owls can make use of nestboxes placed in agricultural buildings or other suitable locations. These nestboxes provide a safe and suitable environment for the owls to raise their young.

Isolated or hedgerow trees can also serve as suitable nesting sites for Barn Owls. These trees offer the owls a perch to roost on and a potential location to build their nest. However, the availability of suitable trees can vary depending on the area and landscape.

Barn Owls can also nest on poles, such as telegraph poles or fence posts. These elevated structures provide a vantage point for the owls to hunt from and a potential nesting site.

Old barns, especially those with suitable openings or cavities, can serve as nesting sites for Barn Owls. These structures offer the owls a safe and spacious environment to raise their young.

Hollow trees are natural structures that can provide suitable nesting sites for Barn Owls. These trees offer the owls a protected space to lay their eggs and raise their young, similar to tree hollows.

Cavities, such as rock crevices or holes in buildings, can also serve as suitable nesting sites for Barn Owls. These cavities offer the owls a safe and hidden location to establish their nest.

Converted buildings, such as old churches or barns that have been repurposed, can also provide suitable nesting sites for Barn Owls. These buildings often retain the characteristics that make them suitable for nesting, such as open spaces or elevated ledges.

Roosting Preferences

Barn Owls have specific preferences when it comes to roosting. They prefer roosting on wood, hay/straw, or stone rather than metal. These materials provide a more comfortable and natural roosting surface for the owls. They may choose to roost on wooden beams, hay or straw bales, or stone ledges within their nesting or roosting sites.

Unlike many other bird species, Barn Owls do not build nests. Instead, they lay their eggs in the bottom of a cavity or on a wide ledge, usually elevated and hidden. The absence of nest building is a unique aspect of their nesting behavior. The owls rely on suitable cavities or ledges within their chosen nesting sites to provide a safe and secure location for their eggs.

Barn Owls do not engage in the process of constructing nests. Instead, they lay their eggs directly on the floor of a cavity or on a wide ledge. The absence of nest building is a characteristic behavior of Barn Owls and sets them apart from other bird species.

The eggs are typically laid in the bottom of the chosen cavity or on a wide ledge within the nesting site. This placement provides stability and security for the eggs during incubation. The owls may choose to line the area with regurgitated pellets or additional nesting material for added comfort and protection.

Historical Nesting Sites

Historically, Barn Owls have made use of specific nesting sites. These include tree hollows and rock crevices. These natural locations provided the owls with suitable nesting conditions and were readily available in the environment.

Tree hollows have been a long-standing nesting site for Barn Owls. The owls would seek out the hollows within trees, which provided a natural shelter and protection for their eggs and young. However, the availability of suitable tree hollows can vary, as they are dependent on the presence of mature trees.

Rock crevices have also been utilized by Barn Owls as nesting sites. These narrow spaces within rocks or cliffs provided the owls with a secure and hidden location to establish their nests. Rock crevices are abundant in certain landscapes, making them a viable nesting option for Barn Owls.

Impact of Farming Practices

Changes in farming practices have had a significant impact on the availability of suitable nesting sites for Barn Owls. Most traditional farm buildings that were once suitable for Barn Owls have disappeared, either through demolition or conversion.

This loss of nesting sites has led to a decline in the Barn Owl population in some areas.

Traditional farm buildings, such as barns and sheds, provided Barn Owls with ample nesting opportunities. However, with changes in agriculture and farming practices, many of these buildings have either been demolished or converted for other purposes.

This loss of suitable nesting sites has made it increasingly challenging for Barn Owls to find suitable places to nest and raise their young.

Suitability of Old Barns and Nestboxes

While old barns and purpose-made nestboxes can be potential nesting sites for Barn Owls, not every structure is suitable. There are certain requirements that need to be met for a nesting site to be suitable for these owls.

Old barns may vary in their suitability as nesting sites for Barn Owls. Factors such as the presence of suitable openings or cavities, the structural integrity of the building, and the availability of nearby hunting grounds can influence whether a barn is suitable or not.

Likewise, not all purpose-made nestboxes will be suitable for Barn Owls due to variations in design and placement.

Access Requirements

There are specific access requirements for Barn Owls when it comes to nesting sites. These requirements ensure that the owls can safely enter and establish their nests.

The minimum hole size required for Barn Owls to access a nesting site is typically around 70 x 70mm. This size allows the owls to enter without difficulty while preventing larger predators from gaining access.

A suitable nesting site should have a minimum width of around 250mm for the nest ledge. This width provides ample space for the owls to establish their nest and comfortably incubate their eggs.

Regional Variation in Nesting Sites

The types of nesting sites used by Barn Owls can vary across the United Kingdom. There are regional variations in the prevalence of certain nesting sites.

In the western regions of the UK, buildings are more prevalent as nesting sites for Barn Owls. This may be due to the availability of old farm buildings or the landscape’s suitability for the construction of farm structures.

In the eastern regions of the UK, tree hollows are more prevalent as nesting sites for Barn Owls. This may be due to the presence of mature trees that have suitable hollows for the owls to use as nesting sites.

Barn Owls do not positively select isolated sites or avoid sites close to human habitation. They have shown no selection or avoidance based on the distance to humans. This lack of selection allows Barn Owls to live in a variety of habitats, including areas close to human activity.
