Australian Creepers: Climacteridae - Diet

birds treecreepers insects radiation

Australian treecreepers are primarily insectivores, insect eaters, with ants composing the biggest portion of their diet. They forage, search for food, for ants and other insects along the trunks and branches of trees they have climbed, especially trees that have rough bark. Treecreepers are known to peel bark, or dig into fissures, cracks, in order to find their prey. Their long claws make it possible for them to hang onto a trunk or branch in an upside down position, but they seldom move downward on a tree. The other insects they eat include beetles, larvae, and spiders. Rarely, a treecreeper might take nectar or seeds in addition to insects.

GREAT AUSTRALASIAN RADIATION

The Great Australasian Radiation refers to the period of time when many different birds evolved across Australia and Asia—the birds evolved in isolation for eons. Australian treecreepers are part of that radiation. Data has indicated that they are related to lyrebirds, scrub-birds, and bowerbirds. The birds' behavior had originally placed them near the northern treecreepers, spotted creepers of Africa and India, and Philippine creepers. But they are not related to any of these birds. Their tree-climbing is an example of convergent evolution, where species develop similar characteristics although they are not related.
