But please note that several shrews and voles have been grey characters. VF, your assumption about the sparrows is most likely correct, but it is hard to tell since they only appeared in Redwall and Mattimeo. King Bull Sparra was described as insane, so his madness was probably what drove him to attacking Matthias, along with being overprotective of the scabbard and belt.
