The theory I'm talking about involves Dromaeosaurids, Oviraptorosaurs, and maybe Therizinosaurs, Ornithomimosaurs, Pterosaurs, and Troodontids having the behaviour similar to that of the Black eagle and Shoebill stork.
Now, to those who don't know what the Black eagle is, the Black eagle (Ictinaetus malaiensis) is a bird of prey. The birds of prey of course consisted of hawks, eagles, falcons, vultures, and owls. The Black eagle is known for letting their children kill each other, which is similar to the Shoebill stork (although, I got that info from Casual Geographic and Be Amazed so I might have gotten and explained that terribly, so if I got that wrong, be sure to correct me). So the theory is, what if Dromaeosaurids, Troodontids, Oviraptorosaurs, Therizinosaurs, Ornithomimosaurs, and Pterosaurs did something similar to that of Shoebills or Black eagles?
Let's take Acheroraptor for example. An Acheroraptor mother is at the nest and it sees 2 of its children fighting each other, it of course watches and let's the stronger sibling kills the weaker one. Or, the Acheroraptor mother is away from the nest and then, while the mother is away, the older/stronger sibling attacks and hurts the younger/weaker sibling, and then, later on, the younger and weaker sibling dies due to its injuries it sustained from the older and stronger sibling.
Because the Dromaeosaurids were likely similar to that of birds of prey, this made me think, what if Dromaeosaurids were similar to that of the Black eagles or Shoebill storks? Think about that for a moment, Dromaeosaurids were similar to that of birds of prey so, if they were similar to that of birds of prey, they probably could have had a similar behaviour to that of the Black eagle, or, though not a bird of prey, the Shoebill storks. Of course, this is just a theory, a paleo theory.
