Population justification: The global population has been estimated at 200,000 mature individuals (Partners in Flight 2020). In North America (USA and Canada), the total population size is estimated at 200,000 mature individuals (Partners in Flight 2020). The species' population in North America (USA and Canada) is estimated to have a slightly positive annual trend, which equates to a rapid increase in population size over three generations (50.01 years) (Partners in Flight 2024). As this region holds the vast majority of the species' global range, the global population size is considered to be increasing at a rapid rate over three generations.
Trend justification: This species has undergone a large and statistically significant increase over the last 40 years in North America (779% increase over 40 years, equating to a 72.2% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
