Conservation of the Dark-rumped Petrel Pterodroma phaeopygia of the Galápagos Islands, 1982–1991

  • Justine B. Cruz (a1) and Felipe Cruz (a2)

Summary

Early work on the Dark-rumped Petrel Pterodroma phaeopygia of the Galápagos Islands, Ecuador, identified colony sites and population status and alerted wildlife managers to an alarming decline in nesting numbers. Predation by introduced mammals, such as rats, cats, pigs and dogs, is the chief concern, followed by loss of nesting habitat to agricultural development. Programmes to reduce predation through poisoning and hunting, begun in 1983, increased the number of chicks fledged from the main breeding colony in eight out of nine years. Pre-breeding adults were lured by tape-recordings to ‘safe’ sites where they successfully raised chicks in artificial nests. Tape-luring offers hope for establishing new colonies on predator-free islands.
