A few weeks ago I caught a fleeting glimpse of a Barn Owl (Tyto Alba) hard at work reducing the local mouse population. These beautiful creatures are one of the most widespread birds of prey in the world, and I held my breath as I watched her at going about her business.
Seeing this magnificent bird got me thinking about the balance of nature, and especially what do about our population of mice. Sure I could lay poison for the rodents, but then I risked killing the owls through secondary poisoning. The problem is not too many mice, but too few birds of prey like the Barn Owl.
The biggest limitation on our population of birds here on the Rock Farm is the number of suitable nesting sites. A lot of birds nest in hollows, and unfortunately these take a long time to form naturally. Whilst the Rock Farm has been blessed with innovative and forward thinking tree planting in the past, sadly there are very few really old trees on the property. This means that nesting hollows are few and far between. This is a problem we shared with our last property, and the boys enjoyed a project there making nest boxes for cockatoos (https://rockfarming.com/2016/10/23/helping-birds-with-nesting-boxes/)
So my lockdown project was to build a nesting box for a Barn Owl.
It was a relatively simple build from some dimensions I found online. I used some old exterior paint I found in the shed to protect it for a few years. The hardest part was mounting it high enough up a tree for the birds to feel safe. I picked an Apple Box near the shed as the site of our first nest box, so I can keep an eye on who might move in.
I knew it would be a bit of a challenge lifting the large box into the tree – and given the soft nature of the ground I decided to put a harness on. Oh and I got my lovely wife to come and keep and eye on me just in case gravity got the better of me.
I must admit I was a little relieved to get back onto the ground safe and sound, with the nest box mounted securely in the tree. I hope the birds think it looks as good as I reckon it does. I hope the old adage, “if you build it, they will come” holds true.
If anyone else is looking a for lockdown project and would like to build some nesting boxes for us to mount in our trees, please let me know. We have lots of young trees that would be the perfect place to mount various sized boxes to support our avian friends.
