Yellow-billed oxpecker (tick bird, Buphagus africanus) perches on the long neck of a Masai giraffe (Giraffa tippelskirchi), Grumeti Game Reserve, Tanzania. In this image I used a vertical format and framed in tightly on the long diagonal of the giraffe's neck against the almost white sky and the tick bird that appears so small compared to the huge expanse of the neck.
