You’re enjoying your morning coffee when a flash of brown catches your eye in the backyard. A rabbit? Maybe. But Phoenix is home to three distinct rabbit species, and what you’re seeing might surprise you.
One’s actually a hare, another stands nearly two feet tall, and the smallest weighs about as much as a bag of sugar.
Learning to tell them apart transforms casual backyard observations into fascinating insights about the Sonoran Desert’s adaptable wildlife.
1. Desert Cottontail
The desert cottontail (Sylvilagus audubonii) is the rabbit you’ll most likely spot in Phoenix neighborhoods, especially in thick, brushy areas with plenty of hiding spots. This true rabbit has adapted remarkably well to suburban life, making itself at home in landscaped yards, parks, and desert edges throughout the metropolitan area.
What They Look Like
You’re looking at a compact animal weighing between 1.5 to 2.6 pounds, roughly the size of a small house cat. Desert cottontails sport grayish-brown fur with a distinctive rufous (reddish-brown) patch on the nape of their neck. Their trademark feature is that rounded, fluffy white tail with a broad white edge that flashes as they bound away from perceived threats. The belly fur is also white, creating a two-toned appearance. Adults measure 14 to 17 inches long from nose to tail.
What really sets desert cottontails apart from their eastern cousins are those ears. They’re significantly larger than other cottontail species, an adaptation that helps them regulate body temperature in Arizona’s extreme heat. Blood vessels in those oversized ears act as natural radiators, releasing excess heat and keeping these small mammals cool even when temperatures soar past 100°F.
Where You’ll Find Them
Desert cottontails stick close to home, living their entire lives within about 10 acres. You’ll find them throughout the Sonoran Desert, but they show a strong preference for areas with thick brush, debris-filled gullies, and landscaped backyards that offer cover. During the heat of the day, they rest in shallow depressions called “forms” under grasses or brush, or they’ll appropriate burrows originally dug by ground squirrels, skunks, or badgers.
These rabbits are primarily crepuscular, meaning they’re most active during dawn and dusk when temperatures are milder. However, during cooler weather, you might spot them foraging during the day. They rarely venture far from safety, staying within a quick dash of protective cover.
Key Insight: Desert cottontails almost never need to drink water directly. They get nearly all their moisture from the plants they eat, including cacti, mesquite leaves, and grasses. This remarkable adaptation allows them to thrive in one of North America’s driest environments.
Behavior and Diet
Desert cottontails are herbivores with a diet consisting of about 90% grass. They also munch on mesquite leaves and beans, fallen fruit, prickly pear pads, and shrub twigs. During drought years, they’ll consume plants with resins and chemicals that would normally deter other animals. Like all rabbits, they practice coprophagy, re-ingesting their feces to extract maximum nutrients from their plant-based diet.
Watch a cottontail eat, and you’ll notice they always feed on all fours, using only their nose to position food directly in front of their paws. They’ll turn vegetation with their nose to find the cleanest parts before eating. The only time they use their paws for eating is when reaching for vegetation above their head on living plants.
These rabbits breed throughout spring and summer, with most young born when new plant growth is abundant. Females may have up to five litters of two to four babies per year, though predation keeps populations in check. Baby cottontails are born naked, blind, and helpless in grass-lined nests the mother digs a few inches deep. She stays away from the nest most of the time to avoid alerting predators, returning only briefly to nurse. Within two weeks, the young leave the nest, though they stick close to protective cover.
Common Mistake: Touching a baby cottontail won’t cause the mother to reject it. The mother appears absent because she deliberately stays away to protect her babies from predators. If you find a nest, leave it undisturbed and keep pets away from the area.
2. Black-Tailed Jackrabbit
The black-tailed jackrabbit (Lepus californicus) isn’t a rabbit at all—it’s a hare, and the difference matters. While this might seem like a technicality, it explains why these animals look and behave so differently from desert cottontails. You’ll find black-tailed jackrabbits throughout Phoenix’s low desert flats, mesquite scrub, and grassy basins, particularly in open areas where they can spot predators from a distance.
Identifying Features
Black-tailed jackrabbits are substantially larger than cottontails, weighing around 8 pounds and standing up to 2 feet tall when alert. Their long, powerful hind legs are built for speed and impressive leaps. The ears are their most striking feature, measuring 6 to 9 inches long with distinctive black tips that give them their name. The top of their tail is also black, creating two key identification markers.
Their coat is brownish-black, providing camouflage against the desert landscape. The body is leaner and more angular than a cottontail’s rounded shape, and those massive hind feet (7 to 9 cm long) are adapted for explosive bursts of speed when escaping predators.
Habitat and Range
These jackrabbits prefer open, flat places with sparse vegetation where they can see threats approaching from far away. Unlike cottontails that stick close to dense cover, black-tailed jacks feel more comfortable with clear sightlines. You’ll spot them in desert areas, agricultural fields, and grasslands. They may travel up to several miles each night searching for food but return to their home range each day.
They handle a slightly less harsh environment than antelope jackrabbits and have a range that doesn’t extend into the southernmost parts of Sonora. In the Phoenix area, they’re common in the low deserts west of the city and throughout open desert terrain.
Pro Tip: If you’re out early in the morning or at dusk and spot a large rabbit with huge ears sitting perfectly still in open ground, it’s almost certainly a black-tailed jackrabbit. They rely on their excellent vision and ability to freeze in place before bolting at speeds up to 40 mph if threatened.
Behavior Patterns
Black-tailed jackrabbits are surprisingly social animals. Large groups of 25 or more congregate, especially on moonlit nights. Their courtship displays are dramatic, featuring high-speed chases, charges at each other, leaps over one another, and sprayed urine. They breed year-round, with females giving birth to one or two babies about six weeks after mating.
Unlike cottontail babies, jackrabbit young are precocial—born fully furred with their eyes open and able to move around within hours of birth. This fundamental difference reflects their hare heritage and open-habitat lifestyle where immediate mobility matters for survival. The youngsters may stay with their mother for several months while learning to navigate their territory.
These jackrabbits are herbivores, feeding on grasses, forbs, mesquite leaves and beans, and cacti for moisture. When they browse on twigs, they leave clean, slanted cuts, distinctly different from the rough, nibbled appearance of cottontail feeding damage. They’re primarily crepuscular and nocturnal, resting during the day in shallow forms under brush or grass.
Where to Spot Them
Black-tailed jackrabbits often flush at longer distances than cottontails when they sense humans approaching. If you’re hiking desert trails west of Phoenix or exploring areas with mesquite scrub and grasslands, scan open areas with binoculars. They’re particularly active during early morning and late evening hours when they emerge to feed. Look for their distinctive silhouette with those enormous ears backlit against the dawn or dusk sky.
3. Antelope Jackrabbit
The antelope jackrabbit (Lepus alleni) is the giant of Phoenix’s rabbit world and the largest hare in North America. These impressive animals inhabit the drier portions of the Sonoran Desert, including creosote bush flats, mesquite grassland, and cactus plains. While less common than their black-tailed cousins, antelope jacks are an unforgettable sight when you encounter one.
Size and Appearance
Antelope jackrabbits can weigh up to 10 pounds and stand nearly 2 feet tall, making them roughly the size of a small dog. Their ears are proportionally even larger than the black-tailed jackrabbit’s, and their overall build is more substantial. The name “antelope” comes from their white sides and rump that flash when they run, similar to an antelope’s warning signal.
These jacks have grayish-brown coats that blend into the desert landscape, but those white patches become highly visible when they’re in motion. The ears lack the black tips of their black-tailed relatives, helping you distinguish between the two species. Their powerful hind legs are adapted for speed and endurance across open terrain.
Habitat Preferences
Antelope jackrabbits favor the driest areas of the desert where vegetation is sparse. They inhabit creosote bush flats, mesquite grassland, and cactus-studded plains, particularly in areas with open space where they can detect predators early. Their range extends into and beyond southern Sonora, with Phoenix representing the northern edge of their territory.
You’ll find them in places where the antelope jack’s larger size and higher food requirements can be supported. They need to consume roughly a quarter pound of food per day, more than black-tailed jackrabbits require. This means they seek out areas with adequate vegetation despite preferring open terrain.
Important Note: Antelope jackrabbits are less commonly seen in urban and suburban Phoenix than the other two species. Your best chance of spotting one is in more remote desert areas southeast of the city or in undeveloped regions where natural desert habitat remains intact.
Behavioral Traits
Like black-tailed jackrabbits, antelope jacks are true hares with precocial young born furred and mobile. They breed throughout the year, and their courtship behaviors mirror those of other jackrabbits with dramatic chases and leaps. The young can move about shortly after birth but may remain with their mother for extended periods.
Antelope jackrabbits are herbivorous, feeding on grasses, forbs, mesquite, and cacti. They require more food than black-tailed jacks due to their larger body size. These hares are primarily active during dawn, dusk, and nighttime hours, spending the heat of the day resting in forms under vegetation.
Their feeding creates the same clean, slanted cuts on twigs that characterize all jackrabbit browsing. During drought conditions, they’ll consume plants that other animals avoid, relying on moisture from cacti and other vegetation since they rarely drink standing water.
Spotting Opportunities
Finding antelope jackrabbits requires venturing into wilder desert areas. Focus on open spaces with creosote bushes and mesquite where they have clear sightlines for predator detection. Early morning and evening provide the best viewing opportunities when they’re actively foraging. If you spot a jackrabbit that seems unusually large with white flashing on its sides as it moves, you’ve likely found an antelope jack.
These animals prefer places with less human activity, so hiking trails in more remote desert preserves and undeveloped areas southeast of Phoenix offer your best chances. They’re less tolerant of human presence than desert cottontails and more skittish than black-tailed jackrabbits, often fleeing at considerable distances when they detect people.
