This is mostly a point of curiosity, since the frog in question isn't my pet and I don't know much about him or her, but if anyone's seen this kind of behavior before, I'd really love to know what was going on -
I was driving in my neighborhood (probably about a half-hour after sunset), and as I was turning around a corner, I saw a Cuban Tree Frog hopping in the road to one side of my car. It wasn't in immediate danger from my car, but I paused to make sure that it actually got safely out of the road, and the frog just stopped in the middle of the road and stared at me (through the open window).
There wasn't any traffic, so I turned off the engine and got out to shoo the frog out of the road. When I nudged it sideways with my foot, though (which usually prompts them to start hopping away, unless they're so freaked out by the whole experience of being stuck in the road that they just freeze), it jumped almost vertically, probably about three feet in the air, and landed a few feet away with a really painful-sounding thump. I tried nudging it again, and this time it jumped high enough to land on my arm for a second before jumping off again.
At this point, I was fairly worried, since I'd never seen a healthy tree frog make that kind of almost-vertical jump. The frog was still next to my feet, so I tried to carefully pick it up to check for injuries. (The only other time I'd seen a frog jumping so erratically was when I found another Cuban Tree Frog with a severe eye injury last year, also in a nearby road, so I thought this frog might have vision or balance problems.)
The frog let me pick it up and sat very calmly in my open hands as I walked in front of my car's headlights for a better view. As far as I could tell, it looked perfectly healthy; it was a medium-size (adorable) Cuban Tree Frog, and it continued to sit on my palm as I held it up to my face and squinted at it. (I know that many wild frogs become much calmer after sitting on a person's hand for a few seconds, but this was an incredibly calm frog.) It wouldn't actually leave my hand when I walked over to the side of the road and tried to put it next to a tree, so I walked a few feet sideways and had to push the frog off my palm to convince it to jump onto the grass.
The clinging-to-my-hand part wasn't all that unusual, especially for a tree frog; I've had to rescue other frogs from roads/other dangerous places before, and many of them seem to decide that I'm essentially a walking tree, once I've picked them up and am no longer a scary giant mammal. The clumsy nearly-vertical jumps seemed strange, though. Has anyone seen that before...? I'm hoping that I didn't just abandon a frog with some significant medical problem on the side of the road, although I know that Cuban Tree Frogs are both invasive and common here (Tampa). They're adorable, though.
