Gulls, or seagulls, were birds transported to Safehold from Earth during the intial terraformation of the planet.

They were typically medium-to-large birds, usually grey or white, often with black markings on the head or wings. They made harsh wailing or squawking calls, and had stout, longish bills, and webbed feet. In many port cities, such as Tellesberg they competed with sea wyverns for food. (BSRA, MTAT)
