The antelope jackrabbit (Lepus alleni), also known as Allen's hare, is a species of North American hare in the family Leporidae found in southern Arizona and northwestern Mexico. Considered the "handsomest" of the hares, it occupies dry desert areas and was one of the last of the North American mammals to be formally described.
The antelope jackrabbit was first described in 1890 by American naturalist Edgar Alexander Mearns, who named it "Allen's hare" (Lepus alleni) after Joel Asaph Allen, curator of mammals and birds at the American Museum of Natural History and the originator of Allen's rule.
Fossil evidence places the genus Lepus as having first appeared in North America approximately 2.5 million years ago. A now extinct jackrabbit species, Lepus giganteus, was thought to exist in North America during this time. This species shared similar physical traits with the antelope jackrabbit, making it difficult to differentiate fossils of the two species. In a 2014 study, researchers hypothesized that L. giganteus served as a common ancestor to the antelope jackrabbit and black... Wikipedia →

With luck
About 10% of wildlife watchers report an Antelope Jackrabbit sighting in Saguaro National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 24 mammals we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report an Antelope Jackrabbit in Saguaro National Park on a given day, against under 5% in April and June, the lowest months. That is one of Saguaro National Park's wettest months, with about 50 mm of rain against almost none in May.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Antelope Jackrabbit sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Saguaro National Park, in our data
Saguaro National Park is the only park on Wallace's Line with enough records to rate Antelope Jackrabbit sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Antelope Jackrabbit is recorded against all the mammals logged in Saguaro National Park (28 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.
