Ferocious for IF

I resisted the urge to draw lions and other beasts for this "ferocious" prompt, and instead followed my interest in birds. How could a bird be ferocious? Roosters can be pretty mean, and there are plenty of people who are afraid of birds. Having recently read about cassowaries I could have gone that direction. But some doodles later, this sketch of a bird over a city emerged. My son calls it a phoenix.

As I was posting this, I heard a terrible frightened sound from our parrot in an outside cage. A Harris's hawk was sitting on top of the cage trying to figure out how to get breakfast. Ferocious!
