The antelope jackrabbit is the giant, white-flanked hare of Arizona’s southern borderlands, and within that narrow band it is a regular sight rather than a rarity. Open occurrence databases hold 477 Arizona records for the species, 303 of them iNaturalist photos, a solid picture for a hare whose entire U.S. Stronghold sits in one corner of one state.
A hare of the southern desert grassland
Almost every Arizona record falls in the south. Records are most frequent in Pima County, followed by Santa Cruz and Pinal, tracing mesquite savannas, desert grasslands, and broad valley bottoms south and east of Tucson. The animal needs open running room paired with grass, forbs, cactus, and shrubby shade. It favors productive Sonoran grassland fed by the summer monsoon over bare hardpan or high forest. Few records occur north of that core, so the map documents a southern Arizona range rather than a statewide one.
Reading the record
Sightings hold up through much of the year because the antelope jackrabbit is a year-round resident, but it is easiest to catch around dusk, dawn, and into the night, when it leaves its shaded daytime form to feed. Cooler weather can push more movement into daylight. The huge, blood-rich ears that let it dump heat are also the field mark that separates it from the smaller black-tailed jackrabbit it shares this country with.
NatureServe ranks the species S3, vulnerable, in Arizona, a reflection of its limited footprint rather than any sudden decline. Loss of grass cover, drought, and road mortality on southern Arizona’s grassland highways are the real local pressures. Saguaro National Park, Madera Canyon, and the Buenos Aires refuge grasslands are among the best places to watch for that unmistakable white-sided run across open desert.
