 This has been interpreted as the re-caching bird projecting its own experiences of pilfering intent onto those of another potential pilferer, and taking appropriate action.Another tactic used by scrub jays is if they are observed caching, they re-cache their food when they are subsequently in private.In a computer modeling study using "virtual birds", it was suggested that re-caching is not motivated by a deliberate effort to protect specific caches from pilfering, but by a general motivation to simply cache more.
