The following game statistics are inspired by this Penny Arcade strip.
This vile feathered creature appears at first a massive, corrupted crow. A disgusting multitude of eyes are mounted above a powerful antlike beak, and four lethal talons ready themselves before a heavy, swinging tail.
This terrifying creature is responsible for night raids on farms that are often mistakenly blamed on dragons or common cattle thieves. Swooping down out of the darkness on massive wings, the powerful bird simply lifts off with livestock in its talons. Its roost is frequently littered with the smashed skeletons of former meals, with recognisable skulls evidencing that the terrible creature has no compunctions about eating human flesh. Growing ever larger with age, truly ancient deep crows are fearsome creatures indeed.

Snatch The deep crow can choose to start a grapple when it hits with its talon or bite attack. If the deep crow gets a hold on a creature of Small size or less, it squeezes each around for automatic talon damage. The deep crow can drop a creature it has snatched as a free action or use a standard action to fling it aside. A flung creature travels 1d6 x 10 feet, and takes 1d6 points of damage per 10 feet traveled. If the deep crow flings a snatched opponent while flying, the opponent takes this amount or falling damage, whichever is greater.
Flyby attack When flying, the deep crow can take a move action (including a dive) and another standard action at any point during the move. The deep crow cannot take a second move action during a round when it makes a flyby attack.
