Popis: Translocations often play an important role in the recovery of endangered species. To\ud assess feasibility for translocation of endangered `Akohekohe (Palmeria dolei), we\ud conducted an experimental translocation of I`iwi (Vestiaria coccinea) from east to west\ud Maui. Mist-netting, veterinary screening of candidate birds, and helicopter transport of\ud healthy I`iwi were successful, resulting in no injuries or mortalities. Translocated birds\ud were assigned to two types of release. Hard release birds were radio tagged and released\ud on the day of translocation. In contrast, soft release birds were held in large cages for 7\ud days and fed artificial nectar. During holding soft release I`iwi feeding rates, fecal\ud production, and mass were monitored. Soft release birds suffered 33% mortality during\ud the holding period. At the end of the holding period, soft release survivors were outfitted\ud with a radio transmitter and released. All translocated I`iwi were followed by radio\ud telemetry for an average of 21 days. Once released, soft release birds showed higher\ud rates of movement, possibly reflecting conflict with established hard released I`iwi. Our\ud results suggest that translocation efforts for wild `Akohekohe will be successful if hard\ud release protocols are followed.
