  1. Control mammalian predators on islands for seabirds

    A before-and-after study on The Chicken Islands, North Island, New Zealand (Parrish 2005) found that nesting success of Pycroft’s petrel Pterodroma pycrofti and little shearwater Puffinus assimilis increased from 20% in 1992-3 to 75% in 1994-5, following the eradication of Pacific rat Rattus exulans from Lady Alice Island (1.4 km2) in 1994. Rats were eradicated using brodifacoum-impregnated cattle feed.
