Hoffmann's Woodpecker - Melanerpes hoffmannii

Named after Karl Hoffmann, this is the most common woodpecker on the Pacific Coast of Nicaragua. The Golden-fronted Woodpecker ranges further north and when the species interbreed, the plumage is intermediate. The tinge or red in the neck feathers might be a clue that this woodpecker is a hybrid.
