General NotesThe North American population of this species has increased by 100% between 1966 to 2006, doubling the population in forty years, according to a recent analysis of Christmas Bird Count and Breeding Bird Survey records conducted by National Audubon Society scientists. Though there is always some inherent variability in the source data, there is a sufficient quality and quantity of data for this species to be able to quantify the change in population with a high level of statistical confidence. |
