Clad in dusty browns to match its grassland or shrubland habitats, the Prairie Falcon is a fast and powerful hunter. It uses its speed in pursuit of mammals more often than many falcons, but will also take birds using high-speed dives.

The Prairie Falcon reaches the northern end of its distribution in the dry grasslands of southcentral British Columbia and southern Alberta and Saskatchewan. The species overwinters from the southern edges of its Canadian breeding range through much of the western United States and Mexico. There are approximately 2,400 individuals in Canada, representing 2% of the global population and a low degree of responsibility for Canada. The Breeding Bird Survey indicates that the population has shown little change relative to 1970, but confidence is only medium because of limitations to survey coverage. The national population of Prairie Falcon is within its goal range.
The Canadian population of Prairie Falcon is best monitored by the Breeding Bird Survey (BBS), which samples a medium proportion of the Canadian range, but has high precision. The trend shows some inter-annual fluctuations, but overall a gradually increasing trend from the early 1970s to early 2000s, and a subsequent decline back to approximately 11% higher than in 1970. This is comparable to the 20% increase over the same period in the continental trend from the Christmas Bird Count (CBC), but the Canadian population is only a very small part of that sample, and overall confidence in the status therefore remains medium based on reliability of the BBS.
The goal for Prairie Falcon is to remain at or above its average population level from 1970 to 2022, based on the Breeding Bird Survey. Recent data show that the population is within its goal range.

Clad in dusty browns to match its grassland or shrubland habitats, the Prairie Falcon is a fast and powerful hunter. It uses its speed in pursuit of mammals more often than many falcons, but will also take birds using high-speed dives.
Prairie Falcon is reported nearly uniformly throughout the year in Canada.
Nesting period starts between late March and mid-April and ends in late July, depending on the region. Before or after this period, the probability of an active nest is lower.
