COCKATRICE

The serpentine tail of the cockatrice is yellow green, its feet and beak yellow, its wings are gray, its feathers are golden brown, and its wattles, comb, eyes, and tongue are red.

They can inflict only minor wounds with their beaks, but their touch will turn flesh to stone (save versus [Petrification] or [be] petrified). 

Note that the petrification aura of this monster extends into both the Astral and Ethereal planes and can thus affect creatures in these planes as well (cf. BASILISK).

Cockatrices are found in temperate to tropical regions, both above and below ground.

The cockatrice is not a strong, steady flyer, and will not go above 300-ft unless provoked into one of its screaming fits of rage. In any case, it will never fly for more than 2-5 turns before landing to rest. 

The cockatrice's power to turn flesh to stone is an awful one, as it often need only hit to destroy its enemies, and those petrified in the air usually fall and shatter!
