Treecreepers favour trees with a rough bark and can be found almost anywhere on the estate where there are suitable trees. They start at the base of the trunk and work their way up the tree looking for food under the bark. They use their long curved beak to search in the cracks. They work their way round and round the trunk, so will disappear from view for a time. If you see a treecreeper, they will often be in a pose similar these. Look at the size of those claws, for gripping onto the bark.

I have seen them from the wildlife hide, but these were in the woods, on the way to the Walled Garden. The two below were on the outside wall the Walled Garden. Note the male is giving food to the female - pair bonding.
