Starting on Valentine's Day the British Trust for Ornithology organises a week of events to encourage everyone to put up a nest box and make a feathered friend. Many natural nesting sites have been lost so nest boxes give birds somewhere to breed and should help secure a future for many of our species. Since National Nest Box Week was launched in 1997, thousands of enthusiastic naturalists across the UK have put up boxes to compensate for this loss. It is estimated that there are now 5-6 million boxes in gardens across the UK.
