Falco mexicanus
The prairie falcon 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.

Time the record covers
At least 2 thousand years on record.
The record covers at least 14 ka to 11.7 ka. No occurrence read is dated outside 210 ka to 0 Mya.
10 occurrences of Falco mexicanus on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
10 occurrences- Pleistocene89%
- Holocene11%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 10 sites for Falco mexicanus, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 10 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not.
