The Southern Cassowary is a tall, flightless bird native to the tropical rain forests of New Guinea and northeastern Australia. It is a treasure to see one of these birds in the wild, even though it is smart to keep your distance. Their numbers are rapidly declining due to a variety of factors–loss of habitat due to the development of the rain forests, fatalities after being stuck by automobiles, competition for food with wild boars imported from Europe, and attacks by wild dogs introduced to reduce the boar population.

These can be dangerous, but you might be thinking of the emu. They are more plentiful. Yes, the do is distinctive!
No, it’s these. They’re labelled deadlyest.
I don’t doubt your information about the dangers of getting too close to these birds. The do looks like it could be a weapon if need be.
Oh , it’s beautiful!
Quite a bundle of feathers! It was such a treat to see one in the wild. I saw one in a zoo once.
