The Nuthatch are small passerine birds found in the woodlands of the northern hemisphere. He follows an omnivorous diet, dining on a mix of insects, seeds and nuts. When foraging, he hops vertically up and down the trunk of the tree, using his slender, but strong, bill to probe into crevices. Larger food will be wedged in a crevice, then pecked at repeatedly until it splinters enough to be consumed. Nests are constructed within a tree hole, and some species will reduce the size of the entrance with mud and resin, offering some protection from woodpeckers. Another species smears blister beetles about the entrance, the stink is thought to deter squirrels.
