Summary

Data on phenology and intra-seasonal population dynamics are described for 52 species of waterbirds resulting from ship-based visual surveys conducted from late June to October 2006 off the northeastern coast of Sakhalin Island, Russia. Estimates of population, age structure and polymorphic manifestations are possible for species that are easily-distinguished by age and individual plumage variability.
