Under the 1992 bird count there were 40,140 breeding pairs of guillemot ("Uria aalge"), representing at least 1.8 percent of this breeding East Atlantic seabird population. Smaller numbers of other seabirds nest at Fowlsheugh, including Atlantic puffin ("Fratercula Arctica"), razorbill ("Alca torda"), herring gull ("Larus argentatus"), and fulmar ("Fulmarus glacialis"). Occasionally a peregrine falcon disturbs nesting kittiwakes as it swoops by the cliff edges. Lesser numbers of lesser black-backed gull ("Larus fuscus"), great black-backed gull ("Larus marinus") and common shag ("Phalacrocorax aristotelis") are also to be found.
