North Seymour Island
Today you will take a morning excursion to North Seymour. The trail on North Seymour crosses the inland through the island and then explores the rocky coast. Along the way the trail passes colonies of blue footed boobies and frigate birds. The magnificent frigate bird, a large black bird with a long wingspan, and a hooked beak, is extremely fast and has excellent vision. Frigate birds are known for the large red pouch on their necks. During mating season the males throw back their heads, inflate the pouch (sometimes to the size of a soccer ball), and shake trying to capture the attention of female frigates.
Boobies and frigates have an interesting relationship. Sharing the same nesting area on North Seymour, blue-footed boobies nest on the ground making their nests from the twigs of the palo santos trees, while the frigate birds nest just above them in the saltbushes.
After lunch you will visit the small sandy island of Mosquera, it’s a relaxing, picturesque stop. Along the rocks and in the tide pool, sally lightfoot crabs (red lava crabs) scamper back and forth, skipping across small pools of water in search of food. These crabs with their bright red shell tops and blue under shells are stunning against the black lava.
