Translocate songbirds
A before-and-after study from February 2003 to December 2005 investigated the reintroduction of 32 rifleman Acanthisitta chloris to Ulva Island, New Zealand in February 2003 (Leech et al. 2007) and found that at least 20 birds survived and bred by November 2003, and offspring were observed breeding in the second year. The 58 rifleman were captured on Codfish Island and kept in 14 x 4.5 x 2 m aviaries for up to four days before release. Of these, 26 died in captivity and transport, including 14 deaths while in the aviaries. Transport mortality was highest when birds were kept in transfer boxes for long periods of time (6-8 hours), or when transfer boxes were in close proximity and birds attempted to attack one other.
