Observe the Nocturnal Wonders: Swallow-tailed Gulls of South Plaza Guide

South Plaza Island offers a unique opportunity to witness the only nocturnal gull species in the world: the Swallow-tailed Gull. These elegant birds, with their distinctive red eye-rings and forked tails, are a captivating sight. Unlike most gulls, they primarily feed at night, preying on fish and squid attracted to the surface by moonlight. Their nocturnal habits make them a truly special inhabitant of the Galapagos Islands. The Swallow-tailed Gull's evolutionary adaptation to nocturnal feeding is thought to be driven by competition with diurnal seabirds. By hunting at night, they avoid direct competition for resources. They nest on the rocky cliffs of South Plaza, often in small colonies. Their breeding season is variable, influenced by food availability. The gulls are endemic to the Galapagos Islands, making South Plaza one of the best places to observe them in their natural habitat. Visitors to South Plaza can observe Swallow-tailed Gulls during both day and night. During the day, you'll see them resting on the cliffs or flying overhead. At night, with the aid of a guided tour and appropriate lighting (red lights are often used to minimize disturbance), you can witness their active hunting behavior. Remember to maintain a respectful distance and avoid disturbing their nesting sites. Photography is permitted, but flash photography should be avoided, especially at night.
