I've raised £250 to provide swift boxes at the church in Dinton, Bucks

This web page here tells the story about swifts in the Anglican Diocese of Oxford. Oxford Diocese has promised to be sympathetic to swifts using their properties, be they existing colonies or potential new colonies. An Oxfordshire-based group of swift enthusiasts were the pioneers but now churches in other parts of the diocese are joining in. We already have a two Buckinghamshire churches with established or establishing swift colonies but a new project has emerged.
This is at St Peter and St Paul Parish Church at Dinton.
This project only requires a modest sum of money to cover the cost of materials required to construct boxes which will be installed in the bell tower. We invite all nature lovers to contribute whatever they can, whether they are residents of Dinton or live further afield.
Should we exceed our target, the excess funds will be used to start up any further swift projects in the county.
