There are numerous different species of bird in the area, and they include the red kite, common buzzard, kestrel, carrion crow, common raven and skylark to name a few of the most obvious residents. The red kite was previously restricted to this and adjoining areas in South Wales such as Mynydd Mallaen, owing to persecution from farmers and gamekeepers who thought (wrongly) that the bird attacked game birds. The red kite has since been re-introduced widely in many parts of Britain, such as the Chilterns and Northamptonshire. The kestrel and buzzard are widely distributed, but the raven is mainly restricted to the higher mountains.
