Genovesa Island, Galapagos--not to be missed!

Each island seems to be my favorite as we move through the Galapagos.  Our visit to Genovesa began with a “dry” landing, where you move from the panga to a quay or rock without stepping into the water.  Genovesa is a tiny island with a very large, circular lagoon open to the Pacific.  It’s a former crater with a section that collapsed, thus opening the lagoon to the ocean.  The entire perimeter of the lagoon is cliffs, and, fortunately, a crack in the cliff wall in one place where you can climb some steps to the flat top of the island.

This is a birder’s paradise.  As we walked across the flat top of the island, we were surrounded by thousands of birds in all directions.  This is nesting season, so we saw many varieties nesting in rocks, in bushes and on the ground.  Genovesa is the main breeding area for red-footed boobies and frigate birds.  We saw parents sharing time incubating their eggs (larger than duck eggs and no more than 2 or 3 in each nest)—one parent sits on the egg while the other goes off in search of fish to feed its mate.

Many of the nests (really a euphemism since most of these “nests” are simply cleared spaces on the ground) had recently hatched chicks, adorable little balls of white fluff with beautiful eyes and beaks.

Some birds were still in full mating frenzy.  Male frigate birds have a bright red pouch under their beaks which they puff out to enormous size when they are trying to attract a female.  Apparently the bigger the red pouch, the better, and dozens of males were displaying their attributes in hopes of enticing a female into mating distance.

There is a small owl on Genovesa, the short-eared owl, that is mostly a ground-dwelling bird.  It hangs out in the rough lava rocks and grabs storm petrols as they swoop close above the ground, tempting fate and sometimes losing.

Genovesa has only one small species of iguana and several lizards, but is mostly a haven for birds, particularly during breeding season.  Some bird species only nest here.

Our next stop was along the cliffs of the lagoon for snorkeling.  We tried two spots, but found the water today to be pretty murky, not as crystal clear as our other snorkeling trips over the last few days.  But—we did see 2 enormous marine turtles eating algae off the rocks on the ocean floor.  When they see anything in the water above them, they take off for the deep ocean, but I was able to follow one for about 50 yards before it dove too far down for me to see it anymore.

These turtles live far out at sea, often traveling thousands of miles in search of food, but come back to the Galapagos Islands to mate and lay their eggs.  Then, they’re off again.  This is turtle breeding season and you can see their tracks on the sand, leading to their nests, holes they dig in the sand dunes where they deposit their eggs and then cover them over with sand.  Having done her job, the female leaves her brood to incubate themselves and heads out to sea again.  She will usually repeat this process 6 to 8 times a season, laying 60 to 80 eggs each time.  The eggs are very vulnerable to predators, including large rats that probably arrived in the Islands on ships, but also pigs that were brought in by farmers more than a century ago.  Once the eggs hatch, it is a mad race for the sea by the tiny, newly hatched creatures, trying to beat the hordes of birds who swoop down to devour them.

Our afternoon visit was to a small beach inside the lagoon, filled with birds, fur seals (uncommon in the Galapagos) and sea lions.  Thousands of birds filled the area around the lagoon with their nests and now their chicks, which have to be ready to fend for themselves in only a few weeks.  Meanwhile, the parents are very busy securing food—fish—and feeding the babies.  Usually only one chick will survive the contest for food and enough safety to survive to adulthood.  We saw many abandoned eggs, probably victims of their parents’ need to beat off starvation and predators.
