  1. Control mammalian predators on islands for seabirds

    A before-and-after study on Madeira (741 km2), Portugal between 1985 and 2000 (Zino et al. 2001) found that the population of Zino’s petrel Pterodroma madeira on the five known breeding ledges increased from 12 pairs in 1987 to 29 pairs in 2000, following black rats Rattus rattus and cats Felis catus control. In 1987 (prior to cat control), ten adult petrels were killed by cats but only four were found dead between 1992 and 2000, of which two had been partially eaten by cats. Rats were controlled using 65 brodifacoum bait boxes, first set in 1986; cats were caught in traps, with eight placed in 1991, increasing to 17 by 2000.
