General Notes

The population of Crows appears to be increasing, according to a recent analysis of Christmas Bird Count and Breeding Bird Survey records. It is possible that the North American population has nearly doubled in the last 40 years. There is sufficient data about this species to have a very high level of statistical confidence in this magnitude of growth.
