Located in the northern part of the
archipelago, Genovesa (also known as Tower) is known to guides as "bird island" because of the many species of birds to nest there.
Because it is somewhat remote, many land species never made their way
there, allowing birds to dominate. Visitors are left breathless by
the thousands of birds who make their home here: you'll see flocks of
storm petrels, mangrove nests of frigates and much, much more.
Genovesa has an peculiar
semi-circular shape: this is because the entire island is the
mostly-submerged rim of a long-dead volcano. One wall of the volcanic
rim collapsed ages ago, allowing water into the caldera. The
remaining walls of the old volcanic rim make for some excellent
snorkeling: you'll see a variety of sealife on and around the crater
walls, and the semi-circular nature of the island prevents strong
currents and winds, making it an excellent site for novices and
intermediate snorkelers.
On the island itself, there are two
main visitor sites: Prince Philip's Steps and Darwin Bay. On the
sandy shores of Darwin Bay you'll see nesting frigate birds, gulls
and red-footed boobys, which although they are more common in the
islands than their blue-footed and Nazca cousins are seen by visitors
less frequently. Keep your eyes open as you hike around Darwin Bay:
there are some tidal pools that occasionally capture some interesting
marine life, like rays or turtles.
If you scale the cliffs via Prince
Philip's steps you will see the same birds, plus possibly the elusive
short-eared owl, endemic to Galápagos and special because it
hunts during the daytime. You'll also likely see finches and
mockingbirds on either hike. Note that Prince Philip's Steps is a
visitor site only available to smaller ships: large groups of
visitors might damage the fragile ecosystem there.
If your visit allows, try to take a
panga ride along the cliffs. Keep your eyes open for a white bird
with a long tail: this is the shy red-billed tropic bird, a fairly
common Galápagos resident but one rarely seen by visitors.
