Description

Recent studies show that breeding bird populations are declining in continental scale. However, there are research gaps for regional dynamics of wintering bird population, especially for common sub-urban song birds. We studied the population dynamics of wintering bird populations in Central Virginia using Christmas Bird Count (CBC) data for the period of 1950 - 2018. Our research showed that several common bird species are in decline (e.g. Northern cardinal, Carolina chickadee) while a few are in incline (e.g. Red-tailed hawk, Common raven). These findings suggest that "keeping common species common" should be a conservation priority.
