The Fluttering Shearwater Puffinus gavia is endemic to New Zealand and has recently been in the news because an unknown number were oiled by the Rena disaster, although at least 198 oiled corpses were found (click here).
Helen Gummer and Lynn Adams report in a 2010 publication by New Zealand's Department of Conservation that 225 Fluttering Shearwater chicks were transferred from Long Island across the Cook Strait to the Mana Island Scientific Reserve during 2006-2008. The project follows on from previous successful efforts to establish Common Diving Petrels Pelecanoides urinatrix and Fairy Prions Pachyptila turtur on the island in an attempt to restore an ecosystem influenced by burrow-nesting seabird activity. At least 191 chicks (85%) were presumed to have fledged successfully in good enough condition to survive post-fledging. The publication describes the selection of chicks, transfer methods and hand-feeding protocols; and presents emergent behaviour, fledging results and a summary of the success of the translocation.
Translocation of chicks to former and to new breeding localities is increasingly becoming a valuable conservation option for burrow-nesting seabirds. Less effort so far has been put into translocating chicks of surface-nesting procellariiform seabirds, such as those listed by ACAP. However, pioneer efforts are being made in the North Pacific with albatrosses, notably with the Short-tailed Albatross Phoebastria albatrus with the on-going attempt to establish a new breeding colony on Japan's Mukojima Island (click here).
It is interesting to speculate what other ACAP-listed species would benefit from translocation exercises to extinct or new breeding sites: for example Tristan Albatross Diomedea dabbenena back to Tristan da Cunha or the Spectacled Petrel Procellaria conspicillata to Amsterdam Island. Maybe one day...
