General Notes

The population of this species appears to be increasing, according to a recent analysis of Breeding Bird Survey records. It is possible that the North American population has increased by as much as 160% 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.
