We have two species of Treecreepers locally. The most numerous is the Brown Treecreeper Climacteris picumnus. It can be found in forest and woodland remnants, particularly where there is an abundance of fallen wood and dead trees. Like all Treecreepers it nests in hollows. Brown Treecreepers like many of our woodland dependent birds have declined in numbers across their range, adversly affected by clearing and fragmentation of habitat. I think they are generally doing well in our area, they are usually one of the first species seen when I am out birdwatching. They are often in small groups, comprising an adult pair and young birds from previous breeding efforts.
White-throated Treecreepers Cormobates leucophaeus are less common although usually encountered in their favoured habitat. They tend to like areas with more mature trees and some understorey of grasses and shrubs. Both species can be found together with Brown Treecreepers favouring the ground and lower parts of the forest for feeding. Male and female White-throated Treecreepers can be distinguished by the female having a small rufous spot on the cheeks, such as the one pictured below.
