WHY DOES THIS CASSOWARY LOOK SAD?

It might be because he is reflecting that, even though he is the world's third-largest bird, he gets little of the respect that he deserves. Even his handsome crest is not enough to elevate him in people's eyes. He might be thinking cruel things about ostriches and emus, and wishing they would go extinct so he could be number one. Then, he feels guilty about wishing for such things. And he feels even less significant as a bird. It's a downward spiral of shame.

I hope that this cassowary feels better at some point in the future, but I think that for this to happen, he is going to have to seriously rethink his assumptions and priorities. Does he have the strength for that level of self-reflection? It remains to be seen. We can but hope.

ps. While I was searching for pictures of cassowaries, I came upon this wholly delightful bit of nonsense)
