Treecreeper clinging onto a tree trunk


At first glance, treecreepers look very much like mice as they hop up tree trunks, which gives them the fitting country name: tree mouse. That is, of course, if you can spot one in the first place, given that their plumage makes for perfect camouflage against the rough bark of an oak tree. Unlike the similar nuthatch, treecreepers can't actually climb down again, and so must leap off and fly to the base of the next tree in their endless search for beetles, earwigs and woodlice to pull out of the bark.
