Control predators not on islands for seabirds
A before-and-after study at a common tern Sterna hirundo colony in eastern Canada (Guillemette & Brousseau 2001) found that fledging success was higher in 1994 when chick-predating gulls (four herring gulls Larus argentatus and one great black-backed gull Larus marinus) were selectively shot, compared with 1993 and 1995, when no gulls were culled (16% of 115 eggs fledged vs. no chicks fledging from 165 eggs).
