Their story
(The surviving account on this page begins partway through the story.)
The writer Giraldus describes a pool frequented by St. Colman's birds, a small duck called teal. Since the saint's time they had become so tame they took food from the hand, and there were always about thirteen, like a small convent.
He reports the local beliefs: whenever the church, the clergy or the birds were wronged, the teal flew away and the pool turned foul until the offender was punished. A bird scooped up by accident would not cook in the pot, and an archer of Robert Fitz-Stephen who shot one is said to have died miserably. A fox that took one was found choked in Colman's old hut, and the bird returned unharmed. These are legends recorded by Giraldus.
Giraldus adds that the pool's water, normally clear, became putrid and useless for people or cattle while the birds were away. A man who drew up a bird by accident at night found his meat would not boil until he returned it to the pond, and then it boiled at once. The fox was found in a little hut on the lake shore, held in veneration as Colman's old retreat, after a frosty night.
