According to Kathy's website:
White Dove Releases are an ancient tradition symbolizing Love & Devotion, Peace & Unity. These Birds mate for life and when released Divine their way homeward and to their nest. These birds are specially bred for their pure white color and natural homing instinct. They are carefully conditioned for your special day to return home safely.
