However, a fundamental problem has been the lack of method standardization (see Woehler & Van Franeker 1995) combined with a lack of method validation, which together could ultimately allow results to be grouped across studies to attain a common goal. Lack of standardization reflects the varying approaches among researchers to reduce factors that bias survey counts—primarily the effect of directional bird movement that is random relative to the movement of the survey vessel (reviewed in Tasker… CONTINUE READING
