Use techniques to increase the survival of species after capture Bird Conservation

A small controlled study on Hawaii in December 1996 evaluated the effects of translocation on common amakihi Hemignathus virens and Japanese white-eyes Zosterops japonicas (Work et al. 1999). Birds kept overnight without thermal support had significantly higher mortality rates (4/10 birds in both species) than those provided with thermal support (0/10 common amakihi and 1/10 Japanese white-eyes), and birds that lost the most weight had the highest mortality. Birds were captured, transported by car for four hours and kept in captivity for 48 hours before release.  All birds suffered weight loss, and fat and protein store depletion, with all deaths occurring within the first 24 hours following capture, regardless of whether the birds were quarantined and then transported or transported and then quarantined. Bird age, capture weight, or fat score did not affect survival rates.
