We used differential counts of white blood cells to determine heterophildymphocyte ratios in the Maui Creeper (Paroreomyza Montana), air endemic, non-endangered Hawaiian honeycreeper, as a measure of stress in response to varying distance and handling technique during translocations. The Maui Creeper was used as an in stru experimental model for the Po'ouli (Melamprosops phaeosoma), an endangered species For whom translocation is critical for its recovery. We translocated 18 Maui Creepers across rugged retrain by hand-carrying individual birds For two distances (1.0 or 2.5 km) inside portable containers. We tested two methods of confinement that varied in the degree of physical restraint during translocation. Birds translocated across longer distances developed significantly higher heterophildymphocyte ratios than those moved shorter distances. However, no significant difference was seen between container types. Our findings build oil a Previous study of stress response in passerines, and indicate that using heterophil:lymphocyte ratios to measure stress may be a valuable tool for evaluating management practices for other critically endangered passerines.
