@Arella Mae,
Arella Mae, I'm glad you like these two pictures. I think they're wonderful.
I'm going to speculate about the fox. Wolves have been seen to make such leaps to get at a small critter that's under the snow. I'm guessing that the wolves' relative is doing the same thing. The high leap is to ensure that the surface of the ice is broken and that the hunter can get to sufficient depth under the snow to get what it's after.
That is such a gorgeous horse that I gasped when I saw it. WOW and thanks.
Edit: We cross-posted. Got a look at the bunnies. Thud with two bounces.
