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 Mesa on a given day, based on 52 verified sightings from GBIF citizen-science data. It is the 203rd most-seen of the 268 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Prairie Falcon in Mesa on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 10 cities where we can rate Prairie Falcon sightings, Mesa ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Las Vegas (United States, under 5%), Phoenix (United States, under 5%) and Denver (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Prairie Falcon is recorded against all the birds logged in Mesa (52 verified sightings), 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.
