Nest Boxes for Tawny Owls

However, due to deforestation and urbanization, their natural nesting sites are becoming increasingly scarce. A tawny owl nest box provides a secure shelter, helping these birds thrive while offering you the opportunity to observe them up close. 

Why do tawny owls need a nest box?

Unlike barn owls or little owls, tawny owls prefer deep, enclosed spaces for nesting. In the wild, they usually seek out large tree cavities or old woodpecker holes. However, as ancient trees are felled and green spaces diminish, tawny owls struggle to find suitable nesting spots.

Benefits of installing a tawny owl nest box

• Supports tawny owl populations – Providing an artificial nesting site helps maintain and increase local tawny owl numbers.
• Encourages natural rodent control – Tawny owls feed on mice, voles, and other small mammals, reducing the need for harmful pesticides.
• Enhances biodiversity – Creating a bird-friendly garden attracts more wildlife and promotes a balanced ecosystem.
• Offers a unique wildlife experience – Watching tawny owls raise their young is a fascinating and rewarding experience.

Choosing the right tawny owl nest box

When selecting a nest box for tawny owls, it’s essential to consider their natural nesting preferences. These owls prefer deep, enclosed boxes that mimic the hollow trees they would use in the wild.

Key features of a good tawny owl nest box

• Deep vertical design – Provides the necessary security for chicks to grow safely.
• Durable, weather-resistant material – Thick wooden or WoodStone construction ensures longevity.
• A large, round entrance hole (about 10 cm) – Allows easy access for the adult owls while keeping predators out.
• Internal ladder or rough surface – Helps young owls climb out when they are ready to fledge.
• Drainage and ventilation holes – Prevents moisture buildup and keeps the nesting space dry.

Best materials for a tawny owl nest box

• WoodStone – Highly durable, weather-resistant, and offers excellent insulation.
• Thick natural wood (at least 20mm thick) – Provides a natural appearance and is a sustainable choice.
• Reinforced screws and hinges – Ensures the box remains sturdy over time.

Where to place a tawny owl nest box?

Placement is crucial to ensure the success of your tawny owl nest box. These owls prefer quiet, secluded areas with easy access to open hunting grounds.

Ideal placement guidelines

1. Height – Install the nest box at least 3-5 meters above the ground.
2. Location – Choose a wooded area, park, or large garden away from human disturbance.
3. Direction – Face the entrance away from strong winds and direct sunlight, ideally southeast or east.
4. Tree selection – Mount the box on a sturdy tree trunk with some cover but a clear flight path.

How to maintain a tawny owl nest box?

Although tawny owls require minimal interference, occasional maintenance helps keep their nest box safe and inviting.

Cleaning and maintenance tips

• Check annually in late autumn – Ensure the box is clean and free from parasites.
• Remove any old nesting materials – Prevents the buildup of bacteria and mites.
• Inspect for damage – Repair any cracks, loose hinges, or broken parts.
• Avoid disturbing the nest during the breeding season – Tawny owls are territorial and may defend their young aggressively.

Encouraging tawny owls to use the nest box

Not all tawny owl boxes are immediately occupied. If owls are not using the box, consider these strategies:

• Ensure a suitable location – If the box is too exposed or too close to human activity, relocate it to a quieter area.
• Avoid artificial lighting nearby – Owls prefer dark environments and may avoid nesting near bright lights.
• Provide nearby hunting grounds – Open fields, meadows, or woodland edges with plenty of small mammals will attract tawny owls.
