Bigger than your average seagull, Laughing Gulls are similar in physical structure to a typical seagull. The yellow beak, legs, and feet are paired with predominantly white body feathers and grey wings.

Laughing gulls can drink both salt and fresh water. Laughing gulls also eat a wide variety of things, including insects and worms, small fish and reptiles. Prey can either be alive or dead. Additionally, laughing gulls will subsist on garbage of sentients.

Colonies of laughing gulls are well-accustomed to the presence of civilization. This often leads to conflict and attacks on sentients and other creatures due to their territorial nature. When a laughing gull chooses to attack another creature, it often isn't alone.

Like their smaller cousins, laughing gulls are monogamous when mating and live in coastal colonies of varying size. Mating season occurs annually, and lasts 3-4 months. Laughing gulls live an average of 30-35 years. It is rare for laughing gulls to venture too far from their colony, unless they mate with another colony.

Laughing gulls make large nests from various vegetation in the area. Females lay 2-3 eggs at a time. Both males and females spend time in the nest warming the eggs. When one parent is warming the eggs, the other goes off for food for itself. The chicks are downy and mobile after hatching, and quickly learn to fly on their own. Until then, the parental pair share the task of feeding the hatchlings.

Every so often, an overlarge egg will be laid during the mating season. These eggs typically hatch what are coloquially called "dire laughing gulls." The so-called dire laughing gulls are much larger when fully mature. Aside from their size, they are identical in behavior and appearance to typical laughing gulls.
