This is the photo I’ve been longing to take. I love the way that the Nuthatch uses old Woodpecker nests, reducing the size of the entrance hole with mud to prevent larger birds raiding its nest, as in this picture. I’ve been keeping a special look out for one, and today, while Daniela and I were doing a Common Birds Census for SPEA, the Portuguese Bird Study Association, I had my chance and grabbed it!
