Kookaburras are tree birds found only in Australia and New Guinea. Â These birds are classified as relatively large birds and their bodies could stretch to as long as 17 inches. Â Kookaburras are also known to be carnivorous birds and this simply means that they feed on other smaller animals like insects, mice, snakes, and other birds. Â One distinct characteristic of kookaburras is the call or sound they make. Their call is likened to human laughing because it resembles the sound that people make when they laugh. Â This distinct call by kookaburras is mainly due to the territorial behavior of these birds. They make the call to basically tell other birds that they own a particular area or territory. Â The kookaburra call is like an announcement that a bird wants to declare a particular territory as his/her own. Â Whenever another bird enters this supposed territory, the kookaburra call could also be warning signal to the visiting bird. Â Most often, kookaburras in a particular territory will call out each other and seemingly laugh together to ward off other birds of a different species.
Aside from its territorial nature, the kookaburra call is also used for communication between other kookaburras. Â Depending on the pitch and tone, the kookaburra bird calls or sings with other birds as a form of communication between themselves. Â In this way, the kookaburras will feel safe and secure knowing that their call is responded with another call from other kookaburras in the area. Â Calling other kookaburras will also help some birds to know if a particular area is free to take over or not. Â Whenever a kookaburra calls and there is no other bird who responds, it may be a sign that the territory is unmarked and uninhabited by other birds and thus it is free for any bird to take over and reside.
