Great Bear Wilderness BFW: Angel in blue jeans

Ptarmigan's explanation was plausible, and to ensure that she was correct, he chomped down on his own leg. "Maybe you're dreaming, but I'm not." The black bird squawked at them, and Viggo hooted in return. "Was that a threat? You—a bird—are threatening wolves? By flapping your wings around?" He could not believe what he was hearing. It was madness, surely, and he wasn't sure he wanted to contract whatever disease this bird was carrying.

So birds really were as stupid as he had always thought. This one just happened to have been taught to speak as some kind of party trick. Without no further provocation needed, Viggo snapped at the bird, attempting to catch her in his mouth and end her life right then and there. The world didn't need such stupid creatures.
