The island is located north of Baltra Island and stretches over 1.9 square kilometers. In spite of its rather small area, North Seymour is home to a large number of animals. One of the largest colonies of blue-footed boobies lives here and you can observe both great and magnificent frigate birds nesting. North Seymour is also home to numerous land iguanas. Land iguanas are not native to North Seymour Island but were relocated from Baltra Island by scientists in the 1930s to provide this species with better living conditions.
