Population justification: The population size has not been quantified, but is estimated to number >10,000 mature individuals.
Trend justification: This species is thought to have undergone a decrease in North America. Taken from long-term trends (Christmas Bird Count data for 1966-2017), data suggest an annual decline of 0.78% (0.26-1.48% annual decline). This would equate to a reduction of 11.51% (4.03-20.79%) over three generations (T. Meehan in litt. 2018).
