General Notes

The Common Tern appears to be declining, according to a recent analysis of Breeding Bird Survey records conducted by National Audubon Society scientists. It is possible that the North American population has decreased by as much as 70% in the last 40 years, although there is insufficient data about this species to be highly confident in the actual magnitude of the population decline. The trend, however, is considered statistically significant.
