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

A small controlled study over the summers of 1986-1988 tested two transportation methods (prior to reintroduction attempts) from Michigan to Ohio, USA (Bocetti 1994) and found that Nashville warblers Vermivora ruficapilla were more likely to survive using a modified technique that provided dark, quiet environments, prompter delivery of food and water and reduced handling time.  When the standard technique for introducing warblers to captivity was used, 79% of warblers appeared to adapt to the captive environment and five birds died. When the new technique was used, 88% and 96% warblers (1987 and 1988 respectively) adapted, significantly more than when using the standard technique. A total of 188 trips (612 km one-way) were made without fatality.
