  1. Control mammalian predators on islands for seabirds

    A before-and-after study on Juan de Nova Island (4.4 km2), Mozambique Channel in July-August 2006 (Peck et al. 2008) found that predation rates on sooty terns Sterna fuscata fell from an estimated 2,205 terns/week to 416 terns/week following the control of feral cats Felis catus. Forty three cats were removed through trapping and shooting, leaving an estimated ten remaining. Predation rates were based on the recovery of 122 tern carcasses, of which 89 (73%) showed signs of predation and consumption and 27 (22%) showed signs of predation but not consumption (‘surplus killing’).
