It's extraordinary to think that the White-throated Treecreeper Cormobates leucophaea, that lives in the eastern forests of Australia, is unrelated to the Northern Hemisphere treecreepers. Any birdwatcher spotting one of these, no matter where they were from, would immediately say 'treecreeper'!
These little brown birds like trees with rough bark, such as the River She-Oak Casuarina cunninghamiana we photographed them on at Uriarra Crossing, a popular picnic and wild swimming spot near Canberra. They have the most remarkable long toes which stick out at all angles and grip on to the tree. Up they hop, circling the trunk and poking into crevices, on the hunt for ants, their preferred food.
