Heermann's Gull territorial dispute

The Seaside Heermann's Gulls are busy staking out nesting territories for the coming breeding season. The gull on the right was minding its own business and preening on the roof of the Holiday Inn Express when the one on the left picked a fight. After a little harmless bickering they went back to their usual gull business. Filming from across the street, my shotgun mic was able to pick up some of the long call, but couldn't quite get the open-beaked call the gulls were making, which sounds almost like a duck's "quack!"
