Question: what is the difference between a nuthatch and an treecreeper?
Answer: The treecreeper is exclusively insectivorous which is why it isn't attracted to bird tables. In contrast, the nuthatch is a seed and nut specialist (hence its name) and is easily drawn to feeders. ... Treecreepers like to nest on trees with thick bark, so they prefer boxes with an open back attached direct to the trunk.
