Southern Cassowary and Emu: is one more dangerous than the other? Emus seem to get treated as more gentle or less dangerous than cassowaries, but is that accurate?
I've seen emus attack people wearing glasses (possibly a reaction to seeing their reflection?) - but it's more of a lunge with the beak rather than any attempt to kick or use their legs.
I've also never seen any emu actually hurt someone - although I've no doubt it happens.
Emus are often allowed to roam free around a zoo or at least in a walk-through enclosure, while zoo staff would never allow the general public into a cassowary enclosure. I don't think that would be as a result of stereotypes - I have no doubt that zoo staff will have seen how aggressive a cassowary can be at times.
In my experience of emus (both in captivity and in the wild), I would generally consider them to be low risk.
