The Laughing Kookaburra is a large kingfisher. They are renowned for catching and eating snakes and other reptiles as well as other bird fledglings. They have a loud and slightly chilling call that sounds like a mad person cackling, hence the name. They are quite fearless of people , security coming from being near the top of the food chain. This bird was sitting beside a walking track in the national park I took early one morning. I suspect it was watching for breakfast.
