Small gull, Red legs black outlined head. The Black-headed Gull was feeding with the other gulls and in the same manor, scraping the concrete walls. The Black-headed Gull was quite protective of its space. If other gulls got near, it would drop its head, open its bill and push at the other gulls as it vocalized. The other gulls were submissive and would move away or fly off. Not once in the nearly 30min did another gull push the Black-headed Gull away.
