Jack

July 16, 2024

While my mind is on the subject of local wildlife residents (see my long-tailed weasel post just a few days ago), I’ve been wondering a bit about the black-tailed jackrabbit (Lepus californicus). Fairly common in our area (and throughout most of New Mexico and the West), it’s always exciting to see one of these swift, long-legged desert “Jacks” bolt and run when spooked. To escape a predator, at the very last moment before discovery, the jackrabbit uses the element of surprise by leaping from his hiding place in the tall grass. The predator, now in hot pursuit, is usually left in the dust as the jackrabbit continues to leap, then leaps/runs until the “Jack” reaches top running speed all the while zig-zagging in an unpredictable manner. And poof! Gone! The predator, now completely baffled, gives up the chase, while the clever jackrabbit lives another day. 

So back to my wonderings.  Just how fast can a “Jack” actually run? How far can he leap? Doesn’t the jackrabbit get its genus name, Lepus, because they “leap?”

What I learned is the top running speed for a jackrabbit is 35-40 mph (Zoom!) and they can leap 15-20 feet in a single bound (super Jack!). Their top speed + their leaping nature allows them to easily escape most predators. But the name Lepus has nothing to do with leaping. Lepus, as translated from the Latin, means rabbit/hare. And one other thing that was news to me …… a jackrabbit is actually a hare, not a rabbit as the common name would imply!   Of course this sparked another wondering.  What’s the difference between a hare and a rabbit?

Various sources cleared up the hare vs rabbit conundrum ….. 

Hares are usually larger than rabbits, have longer ears and black markings on their fur. Hares have 48 chromosomes; rabbits have 44. Hares haven’t been domesticated; rabbits have. Hares live and give birth in shallow depressions in the grass; the young are born fully furred with eyes wide open, able to fend for themselves soon after birth (precocial).  Rabbits usually live and give birth in burrows; the young are born blind and hairless and totally dependent on mom (altricial). Hares usually live alone; rabbits live in large communities called warrens.

There’s so much more to learn, but this will have to do to satisfy my curiosity for now. If you have hares living near you, or perhaps you have a pet rabbit, share your experiences and observations of one or both species.  

P.S. I had fun drawing this jackrabbit (jackhare???), and did so as a gift for a dear friend who happens to love hares/rabbits. Wonder which one is her favorite? I’ll have to ask!

As always, thanks for stopping by!
