Cockatrice ( lesser )

 There is also the lesser cockatrice, though I will not go into detail on that creature, as it is not considered sentient enough.  

-Concering Dragons, Wyverns and Serpents 

Lesser cockatrae are much like their high Cockatrae counterpart, though much less intelligent and large in size. They are often the size of cows, and only have the ability to fly for a short while, as their wings are too small to traverse any large distance.

Lesser cockatrae are common throughout the Dragon Lands and west of the Stallern Mountains, near the Candlemarsh. Lesser cockatrae are hunted for the alchemical properties of their blood and teeth.

Cockatrae use their sharp tail and talons as a lethal weapon during combat, and a slash of their tail can cut through the finest of mail.
