Partnerships among researchers and corporations are continually pushing the advancement of animal tracking technology, allowing smaller animals to be tracked for longer periods, over greater spatial scales, and at finer scale spatial resolutions. Yet the statistical analyses of these data is lagging behind. Using a novel, state-of-the-art network of 57 automated telemetry arrays distributed across southern Ontario, we will develop statistical methodologies to quantify the migratory movements of birds.
Counts of birds passing a geographic location during migration to or from their breeding grounds are often used to estimate long-term population change. However, birds often stop at count sites for several days to fatten for their next migratory flight, affecting probability of detection. The migratory path followed might also vary among years. The influence of such factors on population estimates are unknown.
