The Lava Gull only lives in the Galapagos Islands. Many animals in the Galapagos Islands have evolved in a unique way because the islands are so far away from the continent.
The Lava Gull eats fish, crabs, the remains of dead animals, and food scraps that people throw out.
Most gulls nest in flocks, but the Lava Gull only makes nests in male-female pairs. If another pair comes inside their territory, the gulls fight them off.
A gull with unusually colored plumage
When you think of a seagull, you most likely imagine a bird with gray wings and a white face and body. Most gulls do in fact have either white and grey plumage or white and black plumage. However, the Lava Gull, which lives only in the Galapagos Islands, is unusual for a gull in that it has dark gray feathers all over. It is also the rarest gull in the world and is in danger of extinction.
Natural predators are animals brought to the islands by humans
The Lava Gull is in endangered because of animals brought to the islands by humans. Eggs, chicks, and sometimes even adult Lava Gulls fall prey to dogs, cats, and pigs. Because it evolved in an environment where there were no natural predators, the Lava Gull cannot defend itself well. In the Galapagos Islands, where wildlife has evolved in unique ways, there are many animals now in danger of extinction for the same reason.
