Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
Partners in Flight estimate the global population to number 3.2 million mature individuals (A. Panjabi in litt. 2017).

Trend justification
This species has undergone a large and statistically significant decline over the last 50 years in North America (65.9% decline between 1966 and 2015 based on the North American Breeding Bird Survey [Sauer et al. 2017], 71% decline between 1970 and 2014 based on Partners in Flight [A. Panjabi in litt. 2017]). However recently, overall numbers appear to be stabilising because habitat management has resulted in population increases in Saskatchewan (Jones et al. 1998, COSEWIC 1999, Sauer et al. 2017).

This species breeds in the prairies of Alberta, Saskatchewan and Manitoba (Canada), as well as in North and South Dakota, Montana and Minnesota (USA). It winters in Arizona, New Mexico and Texas (USA), and Sonora, Durango, Chihuahua and Coahuila (Mexico) (Jones et al. 1998).

This is a grassland species. It is reported to depend on habitat structure rather than species composition, and occurs in non-native habitats, although its breeding success in these habitats is unknown (C. Hyslop in litt. 2000).

Conversion of prairie to agriculture has drastically reduced the occupied range and population, but it remains abundant where suitable prairie habitat persists (Jones et al. 1998).
