When you look at a Killdeer (Charadrius vociferus) in isolation it looks boldly-striped—the antithesis of what you’d expect from an animal trying to blend into its background. But in natural settings the black-and-white stripes work very effectively to break up the silhouette of the bird, making it surprisingly hard to spot against the background.
