Laughing Kookaburra

Description:

According to an Aboriginal legend, the kookaburra's famous chorus of laughter every morning is a signal for the sky people to light the great fire that illuminates and warms the earth by day. The legend captures the imagination, but the true function of the familiar cacophony is to advertise the territory of this bold bird.

Habitat:

The Laughing Kookaburra is the largest of the kingfisher family, but unlike most of its relatives, it is sedentary and occupies the same territories the year round. Before spring breeding season, when family groups adjust their boundaries, an observer can actually locate the territories by listening to the noisy choruses at dusk as each group calls in turn and awaits the replies of neighbouring groups. Laughing Kookaburras live in woodlands and open forests. They do not need free water to exist and occur in almost any part of eastern Australia with trees big enough to contain their nests and open patches sufficient to provide hunting grounds. You can see Laughing Kookaburra north of Cape York Peninsula, inland to western fringes of Great Diving Ranges and southwest to Eyre Peninsula.

Notes:

Laughing Kookaburras birth rate is low to keep pace with their longevity, and the population turnover is slow. Kookaburras form permanent pairs and take so long to rear their young to independence that more than one clutch a season is unlikely. Instead of being forced out of the territories on reaching maturity, most young stay to help parents defend the boundaries and rear/protect further offspring. Their nesting season starts in September and finishes in January. They nest a large cavity in almost any object big enough to contain an adult, usually a hole in a tree or termite mound. Incubation begins with the first egg laid of up to four. Incubation and feeding of young is carried out by all members of the group.
