Another mystery solved

As my sister and I were walking through Anandale on our unsuccessful car caper (perhaps a story for another day) I finally, definitely heard a kookaburra! I have been dying to hear one and I saw a couple at the wildlife park in Tasmania (where the 'roo picture is from) but they were stubbornly silent. But this was an honest to god kookaburra call(s) that started out as sort of a fast laugh (I think I have heard that before) that then crescendoed into an incredibly loud monkey laugh. Oo oo ah ah!!!! I think there were two of them, laughing away.
