@Kikohahaha The velociprey/drome along with jaggi/great raptors attack the flying wyvern because rath wyverns attack and sometimes predate on them. Also said rathian could be much too close to their nesting area of the raptors and the adults know that their eggs and hatchlings are in extreme danger. Thus bringing out the feirce paternal instincts of the raptors that drives them to aggressively mob the intruding flying wyvern. You see similar situations today like a pack of wolves attacking a cougar or bear that gets to close to their den that holds their pups.
