Happy Laughing Bird?

The Laughing Kookaburra is native to eastern Australia and makes a very familiar call sounding like raucous laughter. Their call is used to establish territory among family groups, most often at dawn and dusk. One bird starts with a low, hiccupping chuckle, then throws its head back in raucous laughter. Often several others join in. If a rival tribe is within earshot and replies, the whole family soon gathers to fill the bush with ringing laughter. Hearing kookaburras in full chorus is one of the more extraordinary experiences of the Australian bush.
