White Throated Tree Creeper
As the name suggests, white-throated tree-creepers are most commonly seen spiralling up tree trunks - usually eucalypts with rough fibrous bark. They tend to prefer trees with rough barks over smooth so keep an eye out for these types of trees as the birds’ camouflaged plumage can make them hard to see.
The white-throated treecreeper feeds mainly on ants which it snatches in its beak while travelling up and down the bark of tree trunks, but it will also eat other insects and nectar.
