Population justification: Partners in Flight (2019) estimated the global population of mature individuals at 5,700,000.
Trend justification:
Partners in Flight (2019) estimate the population of A. carolinensis to be declining at 2.275% per year, which equates to a ~24% decline over the last three generations (12 years). Similar declining trends are further supported by Rosenberg et al. (2016), the Christmas Bird Count (T. Meehan in litt. 2018) and the North American Breeding Bird Survey (Sauer et al. 2017). As a result, current declines are placed in the range 20-29% over three generations.
