I can only assume that what photographer Porsupah Ree captured here are binkying bunnies. A binky is a playful and happy expression made by a rabbit in which it jumps in the air and twists its body around in a convulsive fashion.

I think these guys might be the ones that inspired the saying “mad as a March hare”. There’s a type of hare that, in March, competes for mates in wildly rapid boxing matches that involve leaping into the air like this, making them look slightly insane.
