Dinosaur Nest 'Trashing'




Ray,
This trashing behavior sounds rather aberrant to me. Crows are pretty smart, and perhaps finding food in human environments is so easy that they flat out get bored. Reminds me of some humans who have an overabundance of time and resources, and resort to non-survival behavior to keep themselves amused (e.g., the explosion of silly Guinness World records).
Since birds and mammals are known to decorate their own abodes with items that strike their fancy (and is definitely of reproductive value in male bower birds for attracting a mate), such behavior might have occasionally occurred in some dinosaurs (non-avian), but not trashing a plundered nest (what a waste of energy).
However, this trashing of a plundered nest sounds like it might be some natural behavior that is being expressed in some unusual way (that has no survival value in a natural setting that I can imagine). Maybe the crow's water supply was polluted and it was a little "brain-damaged". So many possibilities that could cause aberrant behavior in our increasingly unnatural world (is there much pollution in your area?).
Even if a bored or "crazed" dinosaur rarely did such things, the odds of it being of fossilized would probably be close to zero, even in China.
Cheers, Ken Kinman

    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).
