One hypothesis: to keep their broods of hatchlings out of the way of nocturnal 
mammalian predators (by the way this is the same reason that ground birds do it 
today). A T. rex gobbling flocks of small paravians out of tree crowns may 
stretch credulity. But we know for certain that terrestrial Mesozoic mammals 
like Repenomamus or the Deltatheridiid that swallowed Archaeornithoides preyed 
on small juvenile dinosaurs.
