Gust (Ex): As a standard action, a Pidgeotto can trample creatures it flies over. The Pidgeotto merely has to fly above the enemy within 5 feet of it. A Pidgeotto's gust attack deals 1d6 + Dexterity Modifier of subdual damage. A gusted opponent may attempt an attack of opportunity with a -4 to the attack roll (assuming that it has a reach of 5 feet or more). A gusted opponent who chooses not to make an attack of opportunity may instead attempt a reflex save for half damage (DC 10 + 1/2 Hit Dice + Dexterity Modifier).
