Speaking of nests, my wife and I saw (about four years ago) a crow eat
and/or destroy all of a smaller bird's eggs and then -- to our utter
amazement -- it went around the neighborhood picking up every available and
manageable piece of trash, and filled the nest with it! That makes me
wonder if any avian or non-avian mesozoic dinosaurs might likewise have
'trashed' nests after eating the eggs or hatchlings. Do any known dinosaur
nest findings suggest such 'trashing' behavior? I guess it could provide
some survival advantage(s).
