How does a pitohui bird defend itself from predators?

The pitohui bird defends itself from predators by possessing toxic alkaloids in its feathers and skin, which it acquires from its diet of certain toxic beetles. This toxicity makes the bird unpalatable to potential predators. Additionally, the bright coloration of the pitohui serves as a warning signal, indicating to predators that it is toxic and should be avoided. This combination of chemical defense and warning coloration helps the pitohui effectively deter threats.
