Up to 47cm/18.5in in length, it’s larger than its blue-winged cousin (length to 40cm) and by far the largest Australian Kingfisher. Unlike male blue-winged, birds of both sexes have brown tails and are not easily told apart. The third photo shows a breeding pair of Laughing Kookaburras, photographed near their nest site in a tree hollow in the botanic gardens (the Palmetum) in Townsville.

Older males can, however, be distinguished by having bluish rumps,  like one making his presence very audible in the third photo. Kookaburras are very territorial and defend their territories by having calling matches and by performing circular display flights as far as the boundary of the territory. A territorial group consists of either just a breeding pair or a dominant breeding pair and several ‘helper’ birds so the calling matches can be very noisy indeed when everyone takes part.

Juvenile birds are recognisable by the pale brownish scalloped edges to the plumage, most noticeable on the back like the right hand bird in the fourth photo. This bird is barely fledged and has a very short tail.

Kookaburras are carnivorous and they hunt from perches, doing long glides down to catch terrestrial prey, typically large insects and small mammals and reptiles. The bird in the fifth photo has just caught a mouse. They will immobilise their prey by beating it on the perch, and will automatically do this even when fed dead food such as strips of meat.

The original range of the Laughing Kookaburra comprised only mainland eastern Australia from the tip of Cape York in the north south to Victoria and as far west as eastern South Australia. Since european settlement it has been successfully introduced to southwestern Western Australia, Tasmania, the islands in Bass Strait and Kangaroo Island in South Australia. Unfortunately, in these areas it competes with the native wildlife for food and with species that nest in tree hollows such as Southern Boobooks.

Lee’s Addition:

While we were at the National Aviary last summer, we had the privilege of seeing and hearing the Kookaburra in action. Below is the video I took up there. The Kookaburras are in the Alcedinidae – Kingfisher Family of the Coraciiformes Order.

The 5 Kookaburras are the Shovel-billed, Laughing, Blue-winged, Spangled and Rufous-bellied Kookaburra.

Blessed are you who hunger now, For you shall be filled.  Blessed are you who weep now, For you shall laugh. (Luke 6:21 NKJV)
