  • Do nestling calls actually attract predators?;
  • How do parents warn young of danger without betraying nest location to predators?
  • How do young reduce predation risk independently of parents?

I show that vocalizations by scrubwren young are indeed risky, that parents use strategic trade-offs when deciding whether to warn young, and that young learn to use a diverse range of cues about danger.
