I've seen lots of leopard hunting footage over the years, but I've never seen a
leopard leap onto
prey from above.
I've seen them stalking ungulates on the ground, and pursuing arborial prey
like baboons up into
the trees (where the leopard attacks from beneath), but I've never seen them
Do they infact ever leap downwards onto substantial prey? Given that they
large prey to death, I don't see the practicality of them attacking from
anywhere but underneath.
