Often referred to as “Bird Island,” Genovesa supports immense colonies of seabirds, making it one of the most densely populated bird habitats in the Galápagos.

An Island Full of Birds

Genovesa is a sanctuary for seabirds, and nowhere is that more obvious than along the Prince Philip’s Steps trail. From the moment we landed, it felt like we were walking through a live aviary. Every few feet revealed different birds. First, we saw the Nazca boobies. These large, white seabirds with black-tipped wings and yellow eyes are one of the iconic “Big 15” species of the Galápagos. We saw both attentive parents and their fuzzy, down-covered chicks. Some of the chicks were already testing out their wings, flapping them clumsily as they stood in place.

The Nazca boobies didn’t seem to care about our presence. Some sat in the middle of the trail, forcing us to detour. They didn’t beg for food or try to flee. It was clear we were in their space. They looked at us with curiosity, as if evaluating our behaviour. One was even attracted to the bright coloured shoes of someone in our group. We joked at the bird was imprinting on them.

We also encountered several red-footed boobies up close (another Big 15 of the Galápagos ). Unlike the Nazca or blue-footed boobies, red-footed boobies are smaller and more agile in flight, using their dexterity to catch flying fish. They are also the only booby species in the Galápagos that nest in trees, thanks to their strong, grasping feet. Their nesting behaviour allows them to avoid the crowded ground-level colonies favoured by other species.

We also observed many great frigatebirds nesting. We had the fortunate of seeing the males with their red throat sacs inflated like balloons. However, we didn’t see the closely related magnificent frigatebird, which looks nearly identical but differs subtly in iridescent sheen and eye ring.

Further along the trail, we also spotted one of the iconic Darwin’s finches. This one was a brown finch, and though we knew it belonged to one of the local species, it was remarkably difficult to tell whether it was the small, medium, or large ground finch. These species differ primarily by the size and shape of their beaks, which have adapted to different types of seeds. In the field, even seasoned naturalists can find it tricky to differentiate them without observing feeding behaviour or using binoculars to compare subtle proportions. Genovesa is home to several of these species.

Spotting Rarities with a Naturalist’s Eye

We were lucky to be hiking with someone in our group who had spent decades as a professional naturalist. Her eye for detail helped us spot species we would have otherwise missed, including Galápagos doves nestled in a rocky crevice.

Our naturalist companion was able to spot the elusive short-eared owl. The short-eared owl is the only owl on Genovesa and is a daytime hunter, adapted to prey on storm petrels that nest in the island’s lava crevices. Seeing one is considered a highlight by bird enthusiasts.

She spotted this owl even when swarms of birds circled the crater. From a distance it looked like hundreds, maybe more.

I asked the guide how often people got pooped on by birds, and he said “all the time”.

How Did the Birds Get Here?

As we observed the vast diversity of birdlife on Genovesa, a natural question arose: how did all these birds get here in the first place? Genovesa, like all the Galápagos Islands, is of volcanic origin and has never been connected to any continent. That means every species had to arrive by sea or air. In the case of birds, it’s a mix of seabirds and land birds that flew in from the mainland over generations.

Seabirds like the Nazca booby, red-footed booby, and great frigatebird are strong fliers capable of covering vast distances over open ocean. They likely reached the archipelago by chance during migration or storms, eventually settling and breeding. Unlike land birds, which evolved in relative isolation after their ancestors arrived, many seabirds still travel between islands or even back to mainland South America during their lifetimes.

Land birds, such as the Galápagos dove and finches, probably arrived in earlier periods via rafting or wind dispersal and then adapted to island life. Their more limited range makes their evolution within the islands more distinct and well-documented.

Circumnavigating the Crater

After the hike, we boarded zodiacs for a ride around the inner edge of the caldera to get a better sense of its geologic origins. The steep, eroded walls of the crater revealed layers of volcanic tuff – compressed ash from past eruptions. In places, erosion had carved angular overhangs and caves. The crater rim is breached on one side, allowing the ocean to flood in and creating a calm anchorage for small vessels like ours.

Along the cliff face and the trees above, we continued to see more birds nesting. There were even some marine iguanas resting on rocks.

Courting Frigates and a Nap in the Sand

After lunch, we embarked on another short nature. Right as we began, we passed a sea lions sprawled out comfortably on the sand, fast asleep. They lay there without a care in the world, entirely unfazed by our presence. Many Galápagos animals are not concerned with human visitors, as long as we respect their space.

As we continued, we came across a group of nesting frigatebirds in full courtship display, with their bright red throat sacs fully inflated. They flapped their wings, made rattling calls, and shook their inflated sacs in dramatic fashion – all in an effort to catch the eye of a passing female. The sounds and motions were loud and theatrical.

Our guide mentioned research into their mating behaviours, including experiments where scientists altered the appearance of the sacs by painting them blue. Surprisingly, the colour change didn’t seem to affect female interest. In another case, a researcher punctured the sac to study healing – and it reportedly repaired itself within a few days. These stories underscored how much remains unknown about even the most visible species.

A Cloudy Snorkel and Playful Sea Lions

We ended the day with a snorkel along the rocky beach. Unfortunately, the water was too cloudy to see much underwater life. The coarse volcanic rocks made walking on the beach difficult; a few of us got small stones lodged in our flippers, which rubbed uncomfortably against our skin.

But the snorkelling wasn’t the real highlight. Back on shore, a group of sea lions came ashore and began to play. They chased one another, nipped each other’s flippers, rolled onto their backs, and flopped in and out of the surf in an endless loop of games. Their energy and antics entertained us for nearly twenty minutes.

One thing we noticed throughout the trip was the near absence of native terrestrial mammals or amphibians on the islands. Unlike birds or reptiles, which can fly or survive extended periods at sea, most land animals couldn’t make the crossing from the South American mainland. The Galápagos are over 900 kilometres from the coast, and animals unable to float, fly, or raft on vegetation simply never had the chance to colonize these remote islands.

Palaver Point: A Frigid Visit to a Chinstrap Penguin Colony

Palaver Point was our first destination, home to a colony of chinstrap penguins.

Unlike the gentoos and Adélies we had seen on previous days, these penguins seemed to stay close to their nesting areas, seemingly reluctant to venture far in the harsh conditions.

The harsh weather conditions may have contributed to this behaviour, as the penguins sought shelter from the intensifying Antarctic elements.

Despite their limited movement, the colony was surprisingly vocal. The penguins communicated with loud, persistent calls that echoed across the few colonies present. This vocalization might have been related to the weather conditions, or serving as a way for penguin families to maintain contact during limited visibility.

Our hike around Palaver Point proved more challenging than previous excursions. The combination of extremely dry air and intense cold caused my facial skin to dry out and crack. Without a balaclava for protection, my face remained numb throughout the entire expedition on land.

The Antarctic continent is technically classified as a desert due to its minimal precipitation, and the air contains almost no moisture, particularly in these coastal areas where temperatures can fluctuate dramatically. Riding the zodiac only intensified the cold, as the wind cut through every layer, making it hard to focus on anything other than staying warm.

Harry Island: A Zodiac Tour in Whiteout Conditions

In the afternoon, we joined the scheduled zodiac tour around Harry Island, despite the worsening weather conditions. The fear of missing out on a potential wildlife sighting or spectacular ice formation motivated our decision. As we set out, the visibility quickly deteriorated. Heavy snowfall and dense fog obscured the landscape, making it difficult to see much beyond the boat. The ride itself was far from smooth – the zodiac bounced over the rough waters rather than gliding through them, creating a jarring and prolonged exposure to the elements. The splashing got us all wet, making it us all even colder. We passed by a few seals lounging on ice floes, but it was difficult to even pay them any mind.

With the snow reducing visibility, the highlights of the tour were limited to a rock tower emerging from the water and a small grotto. While these geological formations were interesting, the extreme conditions made it difficult to appreciate them fully. It didn’t help either when our zodiac driver was an older fellow who droned on about Antarctic poetry – of all things – while the wind whipped across the open water. Poetry and subzero temperatures are not a great combination. In retrospect, skipping this tour might have been the better choice, and we later learned that many others had opted to stay on the ship instead of braving the cold.

Nature Always Has the Upper Hand

The sixth day of our Antarctic journey provided a valuable lesson in respecting the continent’s unpredictable and extreme environment. They remind us that we are visitors in one of Earth’s most extreme environments, where conditions can change rapidly and where nature always maintains the upper hand.

Zodiac Tour Through Ice and Water

Our excursion took place entirely by zodiac, allowing us to navigate the icy waters and get a closer look at the Antarctic terrain. The weather was exceptionally clear, offering remarkable visibility.

As we floated through the frigid waters, the landscape around us displayed a fascinating variety – flat, smooth snowbanks, jagged cliffs, towering icebergs, and sprawling glaciers.

One of the more intriguing phenomena we observed was “scalloping” on icebergs. This process forms small, golf ball-like divots on the surface of the ice, created by the uneven melting. I tried looking into the science, but it’s actually quite technical, requiring an understanding of fluid mechanics.

Some icebergs even featured long icicles, a testament to the dynamic and ever-changing nature of Antarctica’s frozen landscape.

In some places, the water was remarkably still and reflective, creating mirror-like surfaces that doubled the visual impact of the surrounding landscape.

Humpback Whale Encounter

As we ventured further, we spotted several humpback whales surfacing in the distance. Each whale’s fin pattern is as unique as a human fingerprint. A website, HappyWhale, allows citizen scientists to upload images of whale fins, contributing to global tracking efforts and expanding our understanding of whale migration patterns.

We watched as they gracefully moved through the water, occasionally expelling misty bursts from their blowholes.

Lounging Crabeater Seals

Seals were another common sight throughout the day. We encountered a few crabeater seals resting on ice floes. Despite their misleading name, crabeater seals primarily feed on krill, using their specialized teeth to filter these small crustaceans from the water.

Up close, these seals are surprisingly cute with their expressive faces that appear to be smiling when relaxed. Their primarily white coats with scattered dark speckles help them blend into the snowy environment. When resting on ice, they often adopt a contented pose with eyes half-closed and flippers positioned as if waving to passing boats.

One of the seals rolled over lazily, seemingly indifferent to our presence. The narrator pointed out that it was a female, identifying it by its ventral slit.

It was a simple but fascinating moment – one of those times when I’m reminded how cool it is to watch animals just doing their thing in the wild.

Gentoo Penguin Spotted

We also saw our first gentoo penguin, perched alone on an iceberg.

The moment was made slightly awkward when one of the guests on our zodiac made an odd catcalling noise toward the penguin only to be swiftly shut down by our zodiac driver.

Sailing Onward

After returning to the ship and setting sail for our next destination, we continued to spot small icebergs with seals lounging on them. One particularly interesting sight was a seal resting on an ice floe marked with what appeared to be either guano or blood stains – perhaps evidence of a recent penguin meal.

The crew has yet again planned another successful excursion allowing us to again see another dimension of Antarctica we did not see before.

Bongrain Point

The morning began with a slightly challenging landing at Bongrain Point. Our skilled zodiac drivers carefully navigated through numerous small icebergs scattered across the water. At one particularly difficult passage, one of the crew members actually had to enter the frigid water to push an iceberg out of our path – they were there to make sure their guests were safe and could enjoy the adventure.

Once ashore, we were greeted by a colony of Adélie penguins spread across the rocky beach. The colony had a distinct orange hue – a result of their filthy guano staining the landscape.

We even got to see the adult penguins feeding their young.

We watched as penguins hopped onto the small icebergs near the shore, skillfully balancing on the shifting ice.

Nearby, we spotted skeletal remains of birds, though their cause of death was uncertain. Given recent concerns about avian flu, we briefly speculated about the possibility, though it was more likely a natural occurrence, but we’ll never know.  

Similar to our previous visit to Red Rock Ridge, we remained along the shoreline during our exploration. Looming inland were massive mountains that would present a significant challenge to traverse on foot. Beyond these natural barriers likely lies little more than additional rock and ice formations, as Antarctica lacks terrestrial life forms that cannot swim or fly, with the exception of some extraordinarily hardy plant species and microscopic fauna.

One fascinating geological feature we noticed was the abundance of rocks with remarkably clean splits along the beach. The most likely explanation was probably due to water seeping into tiny cracks in the rocks, then as the ice freezes, it expands, gradually forcing the stone apart.

Lagoon Island

Our afternoon activity shifted from a landing to a zodiac tour around Lagoon Island, allowing us to experience the Antarctic environment from a different perspective.

We cruised past groups of elephant seals sprawled on the shore, their massive bodies lounging contentedly after feeding (I interpret this to be a food coma). We learned that these seals will eventually engage in territorial battles to establish dominance, with the victorious male earning mating privileges with the females – nature’s ancient selection process at work. They are the deepest diving air-breathing non-cetaceans and have been recorded at a maximum of 2,388 m. They eat a wide variety of sea life such as squid, fish, and krill.

Further along our journey, we spotted what initially appeared to be another penguin colony from a distance. However, our knowledgeable guides identified them as Antarctic cormorants. While penguins and cormorants are both black and white, the key distinction is that cormorants can fly, unlike penguins, and their colonies aren’t orange with guano. Our guide shared a helpful identification tip: “if it looks like a penguin but flies, it’s probably a cormorant.”

The zodiac tour also provided a close-up view of icebergs in various stages of melting. Their shapes and sizes were ever-changing, shaped by differences in ice density and shifting weight distribution. Occasionally, when a section of an iceberg melted unevenly, it could rotate about, exposing a fresh surface to the elements.

In the distance, we could see enormous ice mountains stretching across the horizon. The clear Antarctic air created an interesting optical illusion—these massive formations appeared much closer than their actual distance. This phenomenon made it challenging to accurately gauge the scale of the landscape, adding to the otherworldly quality of the Antarctic environment.

Just like the day before, as we experience the continent in different ways, we continue to gain a new appreciation for the immensity and raw beauty of Antarctica – a continent largely untouched by human influence, where nature still reigns supreme.
