Abstract: Lay Summary Defending your home is worth the risk. Great tits communicate for many reasons, but when predators are around, communicating can draw predator attention and is risky. Great tits sing less when predation risk is increased; the benefits of communicating are less than the potential costs of predation. However, when great tits are confronted with an intruder in their territory, they behave the same regardless of predation risk; the benefits of communicating are more than the potential costs of predation.
