General Notes

The population of Ring-necked Duck appears to be increasing significantly, according to a recent analysis of Christmas Bird Count and Breeding Bird Survey records conducted by National Audubon Society scientists. It is possible that the North American population has increased by as much as 250 percent in the last 40 years, although there is insufficient data about this species to be highly confident in the actual magnitude of the population growth. The trend, however, is considered statistically significant.
