Duh, if it 'rests' in trees, it's likely to live more of it's life in
these same trees, if it 'sets' on the ground it's more likely to spend
more time on the ground out of the trees.
 Thus indicating whether or not it's arboreal.  If early dino-birds
perched, they were much more likely to live an arboreal existance,
compared to ones that might have slept laying over on their sides like
a dog, or 'setting' like a duck or emu.
