 148 different species were recorded during 2009 alone—including one new record, a vagrant woodchat shrike which was the first recorded in Warwickshire—and 66 species bred at the site.These figures have been assisted by a nest box scheme; in 2008 there were 49 occupied nest boxes which produced 270 fledged young, and by 2009 these numbers had increased to 65 and 352 respectively, including two owl species, barn owl and tawny owl.As well as birds, the reserve also harbours a varied selection of mammals.
