  1. Translocate songbirds

    A before-and-after study in New Zealand (Taylor & Jamieson 2007) investigated the translocation of 46 saddlebacks Philesturnus carunculatus from Breaksea Island to Erin Island in September 2003 and April 2004 and found that no birds survived until June 2006. Birds carried for an hour before ringing had higher mortality in the first two weeks (20/22 individuals dying) than birds caught within 20 m of the banding hut (9/25 dying). Male saddlebacks with low body condition scores and females with ectoparasites (e.g. ticks, fleas) were most likely to die within 11 days of release. A measure of inbreeding and the total time held in captivity were not good predictors of initial saddleback mortality. Birds were kept in a 2 x 4 × 7 m aviary for up to five days before translocation.
