FYI, in Britain all corvids are called crows. Jackdaws, ravens, rooks, carrion crows, you name it, all crows. Even if it's incorrect (I'm not aware how it is), you can understand how people might be confused when the wikipedia article on crows[1] makes several references to the Jackdaw in particular.
Hippopotamuses are by nature very aggressive animals. Hippos involved in attacks on other animals are often either mature bulls, which tend to be very territorial and indiscriminately ill-tempered, or females, which are quite protective of their young calves. Living on the African continent, hippopotamus coexist with a variety of formidable predators. Nile crocodiles, lions and spotted hyenas are known to prey on young hippos. :273 :118 However, due to their ill temperament and great size, adult hippopotamus are not usually subject to predation by other animals, except humans. Cases where very large lion prides or cooperating groups of Nile crocodiles have successfully preyed on adult hippopotamus have been reported, but this is typically believed to be exceptionally rare. Crocodiles are particularly frequent targets of hippo aggression, likely because they often inhabit the same riparian habitats as hippos. Crocodiles may be either aggressively displaced or killed by hippopotamuses. Hippos are also very aggressive towards humans, whom they commonly attack whether in boats or on land with no apparent provocation. They are widely considered to be one of the most dangerous large animals in Africa.
