Monster statistics extracted from online SRD wiki, not the published hardcover edition.

Though not demons, achaierai are native to the Abyss. They are giant birds, somewhat like ostriches with short necks and four legs each. They attack as 9 hit dice monsters. Their bite attack (1d10 damage) is usable only against foes they can reach—typically those flying or over 8-ft tall. Against smaller creatures they have only two attacks with their talons.

Creatures under 8-ft tall, however, are at an equal disadvantage against achaierai. They may hit the creature’s body (AC 8) only with missile weapons, spears or polearms (such as pikes). If armed with a hand weapon, they must attack the achaierai’s legs (AC -1).
