Translocations often play an important role in the recovery of endangered species. To

assess feasibility for translocation of endangered `Akohekohe (Palmeria dolei), we

conducted an experimental translocation of I`iwi (Vestiaria coccinea) from east to west

Maui. Mist-netting, veterinary screening of candidate birds, and helicopter transport of

healthy I`iwi were successful, resulting in no injuries or mortalities. Translocated birds

were assigned to two types of release. Hard release birds were radio tagged and released

on the day of translocation. In contrast, soft release birds were held in large cages for 7

days and fed artificial nectar. During holding soft release I`iwi feeding rates, fecal

production, and mass were monitored. Soft release birds suffered 33% mortality during

the holding period. At the end of the holding period, soft release survivors were outfitted

with a radio transmitter and released. All translocated I`iwi were followed by radio

telemetry for an average of 21 days. Once released, soft release birds showed higher

rates of movement, possibly reflecting conflict with established hard released I`iwi. Our

results suggest that translocation efforts for wild `Akohekohe will be successful if hard

release protocols are followed.
