caption: The image shows a European nuthatch perched on the side of a tree trunk with moss growing on it. The bird is a light brown color with a white underside and a black cap on its head. Its wings are slightly spread out and its beak is slightly open, as if it is about to take a bite of the moss. Its long, thin beak and legs are tucked in close to its body, and its eyes are focused on something in the distance.
