Of the two following Benedictine saints, the first is often portrayed with ravens while the later is rarely seen with a bird and that is usually a dove representing the Holy Spirit.
ST. IDA of TOGGENBURGIda (Ita) of Kirchberg (d. 1226) was born at Kirchberg Castle, Swabia, the daughter of Hartmann, Count of Kirchberg, and was married to Count Henry of Toggenburg, Switzerland. Henry was abusive, especially when the couple had no children.
According to legend a raven stole Ida's wedding ring. The ring was found by a hunter in the nest of the bird. When her husband noticed the ring on the hand of the hunter, he accused Ida of infidelity. He killed the hunter and Ida fell in anger from the window of his castle. Because of her innocence, Ida had been saved by God but in a miraculous way. The mistake was cleared up, but Ida wanted to dedicate her life to God. Her repentant husband agreed to her becoming a Benedictine nun at Fischingen Abbey where she died in the odor of sanctity. She is also revered as the saint of runaway cattle.
While I could find no reference to birds, there is a very lovely statue at the Monastery of St. Mechtilde on the island of Malta, by the German artist Mark Glass.
The figure shows St. Mechthilde reaching upward - as if she wants to follow birds in their flight. In her hands she holds a nightingale. She is barefoot, balancing on one leg and singing. At her feet are an owl and a raven, birds of wisdom and mystery. The statue radiates energy and vitality.
