Australia Zoo does not actually have any amphibians, however we do have wetlands birds and reptiles so we would be willing to talk about these animals.
Marty is a familiar face around the Zoo grounds. He’s been here for a long time now and is an old favourite with the Zoo Crew. He will always give you a honk good morning, which to us sounds like the punching of a car horn, but to all the other birds in the wetlands it’s a very clear "I’m the boss, I’m the boss!" He doesn’t like anyone to be within his head-butt range (which is about a metre).
