the leap is too short, there's no need to use any aerodynamics, as opposed
to steering by means of the way the animal jumps off). Then it requires
pretty large prey, because small prey is unlikely to stand still (within a
sufficiently small area at least) for long enough that an incipient
Pouncing Proavis would have any chance.
maybe the small prey wasn't used to that sort of a predator....did
Protoavis live near areas that may've been former islands (that re-connected
to the mainland) ?
It goes without saying that someone needs to quantify this. _If_ it
comes out that the model requires, say, that something the size of a weasel
must jump off from a height of 3 m to catch something the size of a pig,
I'll consider the model disproven...
pigs can be little.
I prefer separate explanations. Wings for brooding, then exapted for... who
knows... WAIR or maybe even swimming or...
what's WAIR ? *curious*
