Lore
''Generally posing no serious problem to the traveler, these swift, delicate creatures can peck annoyingly about the head if they are disturbed or threatened. ''

- from "Compendium", Ultima VI

This type of creature is not openly hostile to human beings, but many will probably attack if provoked or frightened.

- from "Fellowship", Ultima VII

''A variety of avian creatures inhabit the land, though an attractive silver-winged creature seems the most prevalent. Preferring fruits and vegetables, birds rarely attack people, though I have witnessed a few that were so inclined. One of the most colorful birds, the parrot, is even rumored to be able to converse in human language.''

- from "Beyond the Serpent Pillars", Ultima VII/2
