The prairie falcon (Falco mexicanus) is a medium-sized falcon found in Western North America. A separate species from the peregrine falcon, with which it shares some visual similarities, the prairie falcon is, essentially, an arid-climate divergence of earlier peregrine falcon lineage. It is thus able to thrive on a more meager, opportunistic diet compared to that of the peregrine, and is generally lighter in weight than a peregrine of similar wingspan. Having evolved in harsher and desert environments, often with low prey density, the prairie falcon has developed into an aggressive and opportunistic hunter of a wide range of both mammalian and avian prey, as well as occasional reptiles. It will regularly take prey from the size of sparrows or finches to birds approximately its own weight, and occasionally much larger.
The prairie falcon is the only larger falcon species native strictly to North America (others are found throughout the Americas and beyond, such as the peregrine falcon with its cosmopolitan distribution). The prairie falcon is resident from Canada (mainly Alberta, British Columbia and Saskatchewan) through the Western United States (west of the Mississippi) and south into Northern Mexico.
Like many raptors and falconiformes, the prairie falcon is popular in falconry; with proper training and care, it is regarded as being equally as skilled as the more well-known peregrine, among others. Wikipedia →

Rare
Under 5% of wildlife watchers report a Prairie Falcon sighting in El Vizcaíno Biosphere Reserve on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 185th most-seen of the 237 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Prairie Falcon in El Vizcaíno Biosphere Reserve on a given day, against under 5% in December to October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Prairie Falcon sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 16
Of the 16 parks where we can rate Prairie Falcon sightings, El Vizcaíno Biosphere Reserve ranks 6th at under 5%. The best odds are in Badlands National Park (United States, about 10%), Death Valley National Park (United States, under 5%) and Joshua Tree National Park (United States, under 5%).
Same genus: Falco
The closest relatives of the Prairie Falcon that you can see in El Vizcaíno Biosphere Reserve (genus Falco, Typical Falcons) are American Kestrel (about 20%) and Peregrine Falcon (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Prairie Falcon is recorded against all the birds logged in El Vizcaíno Biosphere Reserve (16 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
