Note the distinctive white underside and mottled brown upper parts, the Treecreeper is a small bird easy to overlook as it is well camouflaged against the bark of trees. It often looks like a small mouse running up a tree. Note the birds long thin curved bill and eye stripe making it hard to confuse with other common species although there are other similar but rarer Treecreepers.
