I just witnessed such a thing as I have never before seen in my life.

Still in the vicinity of Tucson, Arizona, on a resort in the foothills.
As I posted on another thread, the resort plantings are natural, but groomed within an inch of their lives. A garden really. Guest accommodations are no concentrated high-rise, but little buildings of one floor, scattered around the acreage.

As the sun went down tonight, I was on a lawn chair within a little courtyard surrounded by the "casitas." Watching the hawks and crows harass each other, listening to faraway coyotes (VERY high-pitched yipping), watching thin clouds move in over the previously clear blue sky. The courtyard has generous patches of ... oops ... green grass. Now, I wonder how natural THAT green grass is? Locally indigenous or not, there are these grassy places, and the grass is very green indeed.

And a pair of jackrabbits were simply too hungry
to wait for the humans to turn in for the night.

So the two jackrabbits, one larger and plumper than the other, headed for the lovely green grass and got busy grazing. Serious business, grazing. Very single-minded about it; people walking past on the sidewalks through the grass, and the jackrabbits didn't even budge.

And when no people were moving about, and I was VERY still on the lawn chair,
the dancing started.

BOUNCE BOUNCE BOUNCE on all fours, straight up in the air. A little moving about so as not to get jumped on. I just have never seen the jackrabbits jump straight up in the air and back down where they were,
before, in that fashion.

And no, they did NOT do the dirty deed for which rabbits are infamous.

In the resort clubhouse, I told a staffperson what I had watched.
The rabbits are hungry, the staffperson confirmed, and this is when they come out to feed.
