Peregrine falcon
Cliff ledges provide nesting sites for seabirds including fulmar, shag, black-legged kittiwakes and gulls. Peregrine falcon, chough and raven nest on secluded cliff slopes and carns. Areas of scrub on the cliff tops and in the valleys provide nesting sites for European stonechat, whitethroat and sedge warbler. Grasshopper warblers breed in the scrub associated with the mires at Boswednack, which also provides suitable conditions for wintering water rail, Eurasian woodcock and Eurasian curlew.
