Shrikes will hunt and kill more prey than they can eat in the short term, stashing the prey for later consumption. This habit of killing prey to consume later makes Shrikes adapted to feeding on lubbers. After the lubbers die, the defensive phenolic toxins begin to degrade to non-toxic metabolites. Shrikes will stab and stash multiple lubber grasshoppers. The shrikes never consume the freshly killed lubbers, only those that are properly aged. Two days after Lubbers are killed, shrikes can be safely consume them.
