Translocate wildfowl Bird Conservation

A before-and-after study on Midway Atoll, Hawaii, USA (Reynolds & Klavitter 2006), found that, following the reintroduction of 42 Laysan ducks (Laysan teal) Anas laysanensis in the Octobers of 2004 and 2005, 19 of the 20 birds translocated in 2004 survived their first year. Five of six 2004 females nested in their first year, producing 11 fledgling ducklings by December 2005. Flight feathers of introduced birds were clipped, supplementary feed supplied for the first three months, and individuals monitored with radio telemetry. Although extensive habitat restoration was completed prior to the introductions (including planting native species used as nesting substrates), introduced birds were also observed to use vegetation absent from their original habitat.
