Re: Theropod vs. synapsid: golden eagle kills sika deer in Russia
Golden eagles usually only resort to tackling such risky large prey during the
winter, when smaller
prey become scarce. If given a choice, they'd much rather be tackling something
smaller and less
risky (as would any carnivore).
It makes you wonder whether some of the predator/prey associations infered from
the fossil record
(Deinonychus/Tenontosaurus, Velociraptor/Protoceratops, etc) represent typical
whether they represent rare occurances born out of occasional desperation.
