Galapagos: Genovesa (Part 1 of 2)

The Islander spent the entire day of May 14th anchored inside Great Darwin Bay, the flooded caldera of Genovesa, the "Bird Island," one of the most pristine in the archipelago.
How it looks from above ...
The early morning kayakers returned in time for a landing on the Darwin Bay beach.
They reboarded through a zodiac intermediary.
Most of the rim of the bay is composed of rocky cliffs,
but the promised sandy beach (top of photo)
gave us access.
It was a wet landing, but not bad.
We immediately encountered nazca boobies. They suffer from lesser popularity than their blue-footed and red-footed cousins, even though the black-and-white plumage is striking in its own right.
Birds were flying everywhere above the cliffs,
and, although the breeding season was wearing on, many were still attempting to attract mates, such as this male frigate bird with his inflatable sack.
A red-footed booby! The face and beak were colorful too.
A juvenile waited nearby.
This one has eyes shut. Glare from the sun, or just resting?
It could be incubating an egg, as with this one a few minutes later.
This booby was attempting to maneuver a very large stick into its nest, but it never did fit, and was dropped.
Then we encountered a field mostly of frigate birds.
Lots of red lanterns dotted the landscape, many screeching their mating cry.
A closeup of the sack. Parts of it are feathered!
We inspected the tidal waters. (My camera tends to create vertical stripes when panning a panoramic shot if the lighting changes strongly across the scene.)
Joan found a nearly intact sally lightfoot exoskeleton.
A couple of sea lions were snoozing.
As we waited for the zodiac back to the Islander, I admired these marine iguanas. As usual, they were utterly unconcerned about us.
Then it was time for our fifth and final snorkeling session, along the cliffs on the west side of the bay. I felt like I'd graduated from a five-step program, and now had it all: cycling socks to protect my toes from the fins, a snorkel that fit the mask properly, no need for a flotation vest, the underwater camera in my hand, and the ability to snorkel where there was some wave and current action.
The wave and current action stirred up sediment and other floating bits, so photography was difficult. Some saw a hammerhead shark, but he swam away into the murk before I could get close. I'll give you one highly processed (cropping, contrast adjustment, etc.) photo of a pufferfish, but that will be all.
In the afternoon we'll zodiac over to the east side of the caldera, climb up Prince Philip's Steps, and explore the wildlife there, including owls. (Prince Philip visited the Galapagos in 1965 and 1981.) Next post!

Galapagos: Floreana (Part 2 of 2)

After the first two activities of the day, and before lunch, it was time to go snorkeling for the second time on this trip. Both the advanced and the beginner groups would swim just off Champion Islet, the advanced snorkelers on the more active side in terms of current, and the beginners on the calmer side. However, unlike the first snorkeling trip for beginners, there would be no beach; we would slip into the water from the zodiac and never set foot on a solid surface. This was enough of a step-up in challenge for me that I decided to again use the snorkeling flotation vest, and leave the underwater camera behind. (I will have underwater photos, just later in the trip.)

Lynn Fowler, the expedition leader, accompanied our beginner group. I enjoyed it and felt a sense of accomplishment, although this was the first time I'd swum in a group. I needed to stick close to Joan, my snorkeling buddy, without bumping into anybody else. One highlight was when Joan spotted a chocolate-chip sea star.

After lunch Lynn gave an absorbing presentation on her graduate study work in the Galapagos. To quote from the Lindblad web site:
Lynn completed a doctorate (also at the University of Florida) in 1983, based on her research of the giant tortoises of Alcedo Volcano on Isabela Island, where she spent a year and a half living on the rim of the crater collecting data.
Then the Islander began to sail around Floreana to the site of the first "post office" in the Galapagos. In this photo, taken from the stern, Champion is on the left and Floreana on the right.

It's a wet landing at the post office beach.
Here's the post office. It was established by whalers in 1793; seafarers would deposit letters in the barrel and pick up the ones they could carry onward.
Vanessa explained the history and operation of the post office.
Then all the letters and cards were brought out of the barrel, and the destinations read out by our three naturalists, Vanessa, Christian,
and Jeffo, whose picture hasn't appeared in this blog until now.
There were one or two Ohio-bound pieces, but none close enough for Joan and me to consider hand delivering.

After returning to the Islander there were two activity choices: kayaking and zodiac cruising. Joan and I opted for the zodiacs, but saw some of the kayak operations. Here the kayakers are being helped into their vessels from the embarkation zodiac. (Click on the image to enlarge.)
The kayakers' zodiac kept an eye on things after all the kayaks set out.
This zodiac cruise was the best so far. Early on we approached a beach full of resting sea lions.
The sand must make a great back-scratcher.
Some sea lions were enjoying the surf.
At least one was determined to investigate us.
Sally Lightfoot crabs, and oystercatchers.
Here's a brown pelican.
I love this picture of the snoozing sea lion and the sally lightfoot.
This great blue heron didn't want to pose for me, but instead sat stealthily in the mangrove, where these birds nest.
Two kayakers passed in front of a large mangrove thicket. These salt-tolerant plants have extensive underwater root systems that provide invaluable shelter for young fish and turtles. The extensive nutrients in the brackish water (sea water diluted by freshwater seepage) also encourage bird nesting. The endemic and endangered Galapagos penguins of Isabela island depend on mangroves.
This clump shows that the tide is in.
Kayaks as well as zodiacs must take the channels between rocky islets.
Other tour boats are at anchor here, but we seem to own this patch. The Islander does have the 2pm-6pm slot.
A visit from another Islander zodiac.
Rick shares our zodiac, and he's having a great time too.
Sunset comes quickly at the equator -- the sun doesn't approach the horizon at an angle, but drops straight down.
It's time for everybody to return to the Islander and the evening program.
Not to mention dinner!

Galapagos: Floreana (Part 1 of 2)

This post covers only half of May 10. As with most days of this week-long Galapagos trip, it was almost non-stop.

We awoke at the Galapagos island of Floreana, having sailed west during the night.
Joan and I joined the pre-breakfast outing, which began with a wet landing at Punta Cormorant (named for a wrecked ship, not the bird). In Lindblad-speak, a "wet" landing means the zodiac will go as far up the beach as it can, and then you slide out into an inch to a foot of water and walk the rest of the way. This means wearing appropriate footwear, and perhaps changing it at the beach.

Punta Cormorant is known for its brackish-water lagoon that attracts flamingos, and for having two different kinds of sand: Green Beach, built from ground olivine crystals, and the Flour Beach, made from pulverized coral. Our wet landing was at Green Beach. We split into groups, and Joan and I joined the one led by the naturalist Jefferson "Jeffo" Marquez. A heavy fog hung over our heads as we made our way to the observation point for the flamingo lagoon, where it was difficult to see much.
The trail led up over a low ridge and back down, to the Flour Beach. Green sea turtles nest at this beach.
A frigate bird, hoping to spot an egg or baby turtle, patrolled up and down the beach.
Various other birds were using the beach, including yellow warbler, plover (probably semipalpated, but there are 5 species in the Galapagos), and sandpiper (25 species!) The lighting wasn't good for photographing active little birds ...
Sally Lightfoot crabs abounded.
What are these pits in the sand? (Click on the image to enlarge.)
Jeffo explained that they weren't green turtle nests, but were borrow pits from which the turtles scooped dirt to refill a nest and cover up the eggs. A true nest might be harbored somewhere around the rim.

We returned the way we had come,
to discover that visibility at the flamingo lagoon had improved.
Most of the flamingos were on the far side, sharing the waters with a heron ...
but two came in closer. Our binoculars proved worth carrying into a wet landing.
A striated heron snatched a meal.
Then it was time to return to Green Beach and the waiting zodiacs.
An alert went up! Just down the beach a pair of blue-footed boobies were going through courtship/bonding rituals. Here is a collage (click on the image to enlarge).
Returning to the ship, we launched into breakfast. Afterwards our expedition leader, Lynn Fowler, announced zodiac tours to the islet of Champion, barely off the coast of Floreana, to view wildlife and scout snorkeling locations. Of course Joan and I went. In this photo we're leaving the Islander behind.
There was more than one zodiac ... note the sea lion peeking up at left.
Vanessa Gallo was the naturalist on our craft.
She pointed out these prickly pear cacti, a variety elevated on trunks instead of growing closely to the ground. This occurs on islands where the plants would otherwise be consumed by herbivores including the land iguana, 80% of whose diet is the pads, fruits, flowers, and even spines of the prickly pear.
Also visible on Champion were candelabra cacti.
On our tour we saw sea lions on land, usually snoozing,
and curious pups in the waters around us,
sometimes several at once.
Resting birds included the brown noddy,
and the swallow-tailed gull.
As we turned around a frisky sea lion youngster saw us off.
Snorkeling time was imminent -- in the next post.
