About Brown Treecreeper
Small, with slender downcurved bill and proportionately large, strong legs and feet; upperparts brown with gray head and neck, buff eyebrow, dark patch through eye; upper breast gray with patch of fine streaks in center, black in male, reddish-brown in female; pale buff streaks edged with black on lower breast, flanks and belly; under tail coverts have barred black and white pattern; pale buff wing-band in flight.
The Brown Treecreeper breeds mostly from June through January depending on location. They build a cup-shaped nest in a tree hollow, stump or fence post, which both the male and female build together. The nest is made of grass lined with feathers, hair or fur, with the base built up of grass or the dung of animals, such as horses, cattle or kangaroos. They have 2-3 pink eggs, marked with red and purple streaks and freckles.
This bird is nicknamed “woodpecker” for its tree climbing lifestyle. However, it is not related to the woodpecker; Australia has no woodpecker species. Like their counterparts, the Brown Treecreeper and the five other species of Australian Treecreepers have a distinctive feeding behavior. They climb a tree trunk in spirals with jerky, mouse-like movements, pecking at or probing into the bark for insects as they go, and often continue along into the upper branches.
They live in pairs of up to six birds, usually made up of a breeding pair and the couple’s male offspring, who help feed the female and her young.
