Galápagos Day 3 (morning) - Prince Phillip's Steps, Isla Genovesa

After a long overnight cruise north-east we woke to find ourselves anchored in Great Darwin Bay on Isla Genovesa. This bay is the remnant of a large volcanic caldera where the south west wall has collapsed allowing the ocean to flood in.


Our early morning landing was at Prince Phillip's Steps on the eastern peninsula of the bay. The skies were heavily overcast and it drizzled rain on and off all morning but the birdlife was spectacular. The light remained dull for the whole morning which made for continual juggling of ISO and aperture to get shutter speeds fast enough to capture the birds.

The pangas pulled into a landing at the foot of a cliff which was scaled via a set of "steps"--a combination of steep natural rock steps and cuttings--to the plateau above. Immediately on arriving at the top of the climb, we were scrambling again, this time to assemble camera gear as there were birds everywhere.

Nazca Boobies perched on the rocks at the top of the steps and displaying on the track right in front of us.

Gálapagos Mockingbird looked extremely bedraggled but was singing melodically in a nearby tree.

Hundreds of Great Frigatebirds spiralling in the skies above us. All less than ten steps from the edge of the cliff we'd just climbed.

The walking trail took us across the peninsula to the southern side of the island. There was plenty to keep us occupied on the way - it took over an hour to walk about 1km! It is a National Parks requirement that visitors stick to the trails but this was no impediment to photographing birds with many taking up perching, displaying and nesting sites on or right next to the trail.

Red-footed Boobies prefer to perch in the trees, their prehensile toes able to wrap tightly around the branches.

Nazca Boobies prefer the ground...

so the trail makes a good place for courtship displays,

some completely oblivious to the human activity around them. You are not supposed to get closer than two metres to the animals but Jo was watching some other birds in the trees and these two walked out of the bushes and started bill-clapping right next to her. I managed to grab this shot before she realised they were there and could move away.

Nazca boobies also 'nest' directly on the ground.

Red-footed Boobies build stick nests in the low trees, some right next to the trail.

Red-footed Boobies come in two colour morphs: white and brown and different locations apparently have differing proportions of the two morphs. This colony is mostly brown morphs but we found the 'mixed pair' right beside the trail.

A Yellow-crowned Night-Heron also sat beside the trail looking miserable (it's hard not to be anthropomorphic sometimes).

Not so, the photographer...despite the rain, this place is paradise! The poncho was used as a camera cover. I can still function (well, mostly) when wet, the camera does less well...

As we approached the south coast we came across Great Frigatebirds nesting.

Great Frigatebirds can be easily distinguished from Magnificent Frigatebirds by the colour of the iridescence on the males - green in Great, purple in Magnificent - and the eyering colour in females - pinky red in Great, pale blue in Magnificent.

Juvenile Great Frigatebirds have rust coloured patches on head and neck.

The males of both species, develop large throat sacs of bright red skin during the breeding season.

There is a huge colony of Galápagos Storm-petrels on the south coast and we hoped to find Short-eared Owls, which prey on the storm-petrels as the land next to their burrows in the lava tubes and crevices.

It didn't take long before we started spotting owls stalking around on the lava.

and I managed to see two catch and kill their prey. The capture happened too quickly to be photographed but both these birds hung around post-kill allowing photographs of them with their prey trapped in their talons.

As we were about to leave I spotted this male Great Frigatebird on a nest with the storm-petrel colony and a few pairs of nesting Nazca Boobies in the background, capturing the essence of the morning.

 It was still raining when we got back to the boat but I spotted this Red-billed Tropicbird flying around the cliffs and a flock of Great Frigatebirds decided that the rigging on the sailing ship anchored nearby made for a good roosting spot so I couldn't resist breaking out the camera again.
