Effect of sampling blood of nestlings on success of fledging in white-eyed vireos (Vireo griseus).

摘要

Because the white-eyed vireo (Vireo griseus) is a less sensitive species than the endangered black-capped vireo (V. atricapilla), it served as a proxy to quantify potentially adverse effects of sampling blood. Success of fledging was quantified using split-sampled broods with non-bled nestlings serving as a control. Sex ratio of broods was determined, and sampling and storage methods for blood were assessed. Obtaining blood from nestlings did not affect success of fledging. The male:female ratio of nestlings was 65:35.Digital Object Identifier http://dx.doi.org/10.1894/0038-4909-57.4.446
