Tackles McCann

And the first one came leaping out of the air at him with its hind legs held back, then it slashed them forward. He saw it only as a blur before it crashed into his chest and knocked him down. As he fell, his fist convulsed on the pistol grip of his rifle, and it went off in another tearing crack of automatic fire.
The thing was on top of him, ripping, shearing away his flesh in flurries of shining claws. He screamed as the claws ripped open his belly. The thing raised its bird-like head and squawked again.
More of its fellows joined it, leaping into McCann's dying vision and starting to tear at his body as he lay twitching, his insides steaming as they were scattered through the ferns. The pack fed, crooning and squabbling and hopping up and down.
Like sparrows at a bird feeder.
