Here's a question for your deliberations (please) from an observant Mt Rogers walker this morning.

Presumably Sulphur Crested Cockatoos don't deafen themselves with their own screeches. Would the way they fly &/or their aural structures prevent self-deafening?

Perhaps they have selective hearing?

Thanks

Rosemary
