Population justification: This species is not well known, however the population size has recently been estimated at 170,000 mature individuals (Partners in Flight 2019).
Trend justification: This species has undergone a drastic decrease over the past decades in North America. Long-term data from Partners in Flight Landbird Conservation Plan suggest the species’s population decreased by 94% between 1970 and 2014 (Rosenberg et al. 2016). Declines are currently estimated at ~5.7% per year, which equates to a 48% decline across three generation lengths (~11 years) (Partners in Flight 2019) and similarly significant declines are extremely likely to continue into the future. Such declining trends were similarly concluded by the North American Breeding Bird Survey (Sauer et al. 2017).
