We also heard about a scheme running in Stevenage to encourage swifts - tenants can opt to have a swift nest box installed in their roof as part of routine roof work. The population of swifts has dropped by 40% in the last 15 years, as breeding sites have been lost, so this project is trying to increase the breeding sites available to swifts.
Sarah also told us about the 2012 Members Day, Wild in the City, which will take place on Saturday 27th October, in Cassiobury Park Local Nature Reserve. As well as guided walks, games and activities, the 'Urban Birder' David Lindo will also give a talk. David has worked on television programmes such as Springwatch and The One Show, and believes that you don't need to go out into the countryside to appreciate nature: the wildlife in our cities can be just as fascination.
