Contrasting reactions of loggerhead shrikes to two types of chemically defended insect prey

  • Reuven Yosef

Feeding tests with loggerhead shrikes (Lanius ludovicianus) showed this bird to acceptUtetheisa ornatrix, a moth (Arctiidae) protected by pyrrolizidine alkaloids, but to avoidLytta polita, a beetle (Meloidae) containing cantharidin.

Key Words
