Below: A Heermann's Gull with aberrant white patches. I couldn't help but wonder if this would benefit the individual by adding a jaeger-like flash of white to its wings. I watched one individual chasing a jaeger that was chasing an Elegant Tern. Could the extra flash of white increase its chances of kleptoparasitism success?
