谁能介绍下笑翠鸟（要用英文）

The kookaburras, also known as the "laughing jackass", is a special bird in Australia. Its voice is hoarse, so it is often used as background voice in movies or TV programmes when people want to show the sound of jungle. The kookaburras is about 46 centimetres and weighs about 500 grams. It is the largest in size among all species of kingfishers. It mainly perches in Eastern Australia, but now it is successfully introduced into Western Australia. Unlike other species of kingfishers, it does not eat fish, but feeds on mice, little birds, snakes and insects. While in the west, it also takes chickens and ducks as food.
