At a public park I asked a passerby if he had seen any Kookaburra around and he said "Nope, but you will hear 'em before you see 'em". I thought that was funny.
The next day we drove about half an hour out of town to search at a different place. When my wife told me she heard some people laughing I quickly ran to the location and scanned the treetops. There they were 2 pairs of Kookaburras making noise. I don't know what joy they had mocking people, but we were entertained. We heard 'em and we saw 'em.
