Re: FW: The ground-nowhere hypothesis on the origin of bird flight (joke)
Hmmm. Perhaps the drop-bear is attracted to camera straps?
More seriously -- mammals need to eat way too often to be able to just sit in a
tree and wait for something to happen to walk underneath them. There is another
factor too; most prey is alert enough that missing your initial pounce is
likely, and if a prey species are slow movers, then actively searching works
better than waiting anyway. All in all, I think pouncing is highly over-rated,
at least in today's world.
The local anoles seem to use it w/ success on insects, though, so I think it
still plays in flight evolution cartoons.
Humans hunt deer from trees of course, w/ good success, but use projectile
weapons to greatly increase their killing range as well as various baits,
scents, and calls. I once calculated the cost of licensing, special clothes,
weapons, trucks, refrigeration and other accessories and came up w/ a total
cost 250$US/lb for venison (although assuming 2 deer/year for 10 years, and 10
years per truck it gets closer to 15$US).
