Our answer: The winter song of Northern Shrike–a fearsome predator if ever there was one–frequently includes imitations that are attractive to the smaller birds that make up a significant part of the shrike’s winter diet. The Gray Butcherbird of Australia is also said to use a similar hunting technique.
