Population justification: The global population is estimated to number 20,000-40,000 individuals (H. Whitlaw in litt. 2007).
Trend justification: This species is declining rapidly (Rogers 1997; Wolfe et al. 2007), owing to conversion and development of prairie grasslands. It has undergone a large and statistically significant decrease over the last 40 years in North America (99.6% decline over 40 years, equating to a 75.7% decline per decade; data from Breeding Bird Survey and/or Christmas Bird Count [Butcher and Niven 2007]).
