Choosing a Nest Box

Across Australia, natural tree hollows are becoming increasingly difficult for wildlife to find.

Many native birds, parrots, owls and possums depend on these hollows for shelter, raising their young and escaping predators. Unfortunately, suitable hollows can take well over a century to develop in mature trees.

Installing a well-designed nest box is one simple way to help replace this lost habitat and support local wildlife.

Let's look at how to choose the right nest box for your backyard.

🌳 Why Nest Boxes Matter

Many Australian animals cannot build nests from scratch.

Instead, they rely on natural tree hollows that have formed over many decades through weather, insects and the natural ageing process of large trees.

As older trees are removed from urban areas, suitable nesting sites become much harder to find.

A properly designed nest box can provide an important alternative for many native species.

🐦 One Size Doesn't Fit All

Different animals require different nest boxes.

The most important feature is the entrance hole, as it determines which species can safely use the box.

Smaller entrance holes suit small parrots and other cavity-nesting birds, while larger openings may be required for larger birds or possums.

Choosing the correct hole size also helps reduce competition from larger animals.

🦉 Which Species Can Use Nest Boxes?

Depending on the design, Australian nest boxes may be suitable for:

• Rainbow Lorikeets
• Crimson Rosellas
• King Parrots
• Eastern Rosellas
• Kookaburras
• Microbats
• Brushtail Possums
• Ringtail Possums

Each species has its own preferred entrance size and internal dimensions.

🪵 Why Timber Matters

Natural timber provides excellent insulation against changing weather conditions.

Compared with many synthetic materials, timber helps keep nest boxes cooler during summer and warmer during winter.

Using reclaimed timber also gives new life to quality materials while reducing waste.

📍 Where Should You Install a Nest Box?

Choosing the right location is just as important as choosing the right box.

For the best chance of success:

• Mount the box securely to a healthy tree.
• Place it well above ground level.
• Avoid direct afternoon sun where possible.
• Provide a clear flight path to the entrance.
• Keep the entrance away from prevailing wind and heavy rain.

Different species have different preferences, so the ideal height and location can vary.

🛡️ Help Keep Wildlife Safe

A good nest box should be designed with the safety of its occupants in mind.

Useful features include:

• Drainage holes to prevent water build-up.
• Ventilation to reduce heat.
• A sloping roof to shed rain.
• Strong construction for long-term durability.

Regularly inspect the box from the ground for signs of damage, but avoid disturbing wildlife during the breeding season.

🌿 Be Patient

It may take weeks or even months before wildlife discovers a new nest box.

Some boxes are occupied surprisingly quickly, while others remain empty until local animals become familiar with them.

Patience is part of creating a wildlife-friendly backyard.

Frequently Asked Questions

Will birds use a new nest box straight away?

Not always. Some birds investigate quickly, while others may take months before nesting.

Can possums use a bird nest box?

Usually not. Possums generally require a larger entrance hole and a larger internal space than most bird species.

Should I clean out my nest box?

If the box is unoccupied, it can be checked and cleaned when necessary. Avoid disturbing nesting animals during the breeding season.

Can I paint a nest box?

If painting is desired, only use wildlife-safe exterior finishes on the outside of the box. The inside should remain untreated.

How high should a nest box be installed?

The ideal height depends on the species you're trying to attract. Research the requirements for your local wildlife before installation.

Final Thoughts

Installing a nest box is one of the most rewarding ways to support Australian wildlife.

By choosing the right design and installing it in a suitable location, you can help provide safe shelter for birds and possums while bringing more native wildlife into your backyard.

Even a single nest box can make a valuable contribution where natural tree hollows are becoming increasingly scarce.
