2 Swallow-tailed Gulls at Prince Phillip’s Steps on Genovesa in Galápagos, EC

These swallow-tailed gulls were sleeping among the rocks in the early morning rain until rudely awakened by tourists trudging up Prince Phillip’s Steps. You might joke the bright red rim around their eyes means they were out all night. They were. The creagrus furcatus is the only gull species in the world that feeds nocturnally. Their primary diet is squid augmented by small fish. Approximately 35,000 swallow-tailed gulls live in the Galápagos. A large percent of the 50 colonies are here at Genovesa and two other eastern islands.
