Re: L'origine et l'évolution des oiseaux, with a twist

The key to this thread is long legs (longer tibia than femur) = cursor.

Possible, but not a given.

Help me think of an exception.

Not sure about leaping, other than that last arboreal fling before becoming airborne.

Why would you expect them to run to takeoff speed ? Like most everything else that small, it would appear at first blush that they could probably leap to takeoff speed. If so, why do it the hard way.

You're reading into it.

It can walk.
It can run.
It can leap.
It can glide.

No implied order to any of these activities, especially if arboreal.
