Here is a White-throated Sparrow from back in the fall. White-throated Sparrows can be either tan morph or white morph, and this is a tan-morph individual. Color morph does not indicate the bird’s sex, but individuals almost always mate with a bird of the other color morph. So, a male tan morph will made with a female white morph, and a female tan morph will mate with a male white morph.
