We recently had a conversation about what cassowaries might have had to
deal with--so, the presence, number, and type of predator on these birds
is unresolved. I made the point that aggressiveness is viable only when
the prey has a chance of winning. This probably was the case with
cassowaries. It is patently _not_ the case with ostriches
vs. lions.
