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 by gamekeepers in the rest of the country, but has since been introduced widely in southern Britain, such as the Chilterns. The kestrel and buzzard are widely distributed, but the raven is restricted to the higher mountains. There is a wide distribution of mammals such as field voles, red foxes and badgers as well as many songbirds. The skylark is plentiful due to the extensive rough pasture present below the main peaks which allows ground nesting of the species. Pied wagtails are common near the streams and torrents running from the hill tops.
