Natural nesting sites for many species of birds are rapidly disappearing. As we continue to modify the landscape to suit our own needs (agriculture, housing, etc.) its all too easy to forget about how wildlife is affected, especially birds, and how our actions have a direct impact on their lives. Birds in particular have had a rough time with the destruction of many of their normal nesting habitats.
Our gardens can play a massive part in redressing this imbalance. Planting hedges in or around our gardens is a fantastic way to provide shelter, safety and breeding places for many species of birds and wildlife in general. However, there are a number of cavity nesting birds that prefer a more enclosed nest site. Each species has its own particular requirements, although birds can be remarkably versatile and opportunistic, seeking out the most unexpected nest sites if insufficient natural holes are unavailable. Putting up a nestbox or two in your garden is a great way to help create more potential nest sites for many of your garden bird visitors. The sight of young birds fledging from a nestbox never fails to lift your spirit, whether you are a casually interested home-owner or an avid bird watcher!
