Scruvo was the male leader of a gang of jackdaws residing in Saint Ninian's. He was attracted to shiny objects, as most of his kind are. Like his gang, he was a thief, and was responsible for taking one of the Tears of all Oceans from a house martin's nest in Redwall Abbey.
He and his group viciously attacked Craklyn, Gerul, Piknim and Tansy; Tansy, Craklyn, and an injured Gerul survived, but Piknim unfortunately died.
Scruvo was killed by Rangapaw, the daughter of Skipper. He is a very minor character, nothing else is known.
Scruvo is the only named jackdaw in the Redwall series.
