I don't see how that's relevant to the question of whether frogs "mind" being skewered by birds, which is the question I read from your post.
>They mind it about as much as we do, judging by how hard they try to avoid it
If there's an example of something trying hard to avoid it that's clearly incapable of minding anything, then you cannot establish a certain link between the capacity of minding it and trying to avoid it
