The more I think about it, the clearer it is that the crab is the clear winner in this comparison, even though I have not laid eyes on this supposed dancer. Maybe the dancer was named after the crab and not the other way around. It would seem more fitting, at least.

It's handsome, too, with an array of colours to rival any burlesque outfit. It definitely gains points on the dancer in the eye-stalk department, a feature which I've always loved in all creatures that wear it. 👇

The Sally Lightfoot (Crab) is, in my opinion, more agile on its numerous appendages than any human is on two. It skitters across jagged lava on pin-point feet as though it was floating through the air, with scarcely a bump or bobble to interrupt its gliding gait. 👇

The Sally Lightfoot Crab is allegedly named for a colourful Caribbean dancer who was light on her feet. I don't know if that's insulting to the dancer or the crab, but I think I'm offended on behalf of both. What sort of dancer has ten legs, anyway? 🧵

Distinct enough is this brooding heron that it was recently elevated to a species of its own, the coolly-named Lava Heron (part of a three-way split of Striated Heron). Definitely a distinction well-deserved for one of the foxiest herons around.

This dark-mode perfection serves a purpose, as the shorelines of the Galapagos are largely made of hardened lava, which is black. Like a vigilante in the night, then, the heron stalks its prey and avoids attackers under the cover of darkness, albeit in daylight. 👇

The Striated Heron, Galapagos Edition™ trades the subtle blues and jaunty cap for a smart and sexy black suit, with a little oil-slick iridescence for intrigue and a jarring pop of colour to draw the eye. It's as handsome as Bruce Wayne and as dark and mysterious as Batman. 👇

Until very recently, you could find a Striated Heron in nearly every warm part of the world. They varied a little from place to place, but you'd pretty much recognize them wherever you went. Except, perhaps, in the Galapagos. 🧵🪶

It's fascinating to imagine Darwin (and his cohorts) envisioning from scratch these ideas that we so easily accept today. It just goes to show that if you want to be a revolutionary thinker, you need to stop looking at boobies and focus on what really matters.

This diversity represents the process of adaptive radiation, where one species divides and conquers varying habitats or food sources. There is little competition on the Galapagos, so there are 17(ish) species of finches today occupying every available niche. 👇

The Galapagos finches are not finches at all, but tanagers descended from continental stock. They are strikingly similar in almost every way, but their beaks range from the chunky wedge of the Large Ground-Finch to the slender forceps of the warbler-finches. 👇

Nevertheless Darwin imagined that these birds all radiated from a single, South American ancestor at a time when the prevailing argument was "God did it", so credit where credit is due. He was right, not just about the radiation but about the point of origin for these birds. 👇

It wasn't their overwhelming beauty that piqued Darwin's curiosity, but the variation in beak size and shape. It's a good thing he had a keen interest in the details. In his shoes I'd be too busy ogling boobies (yes the birds) to revolutionize our understanding of biology. 👇

A small, grey bird is standing on a fern leaf. It has a very slim, pointy beak.

The finches of the Galapagos are famous as the inspiration for Darwin's ideas on evolution. Just as well, too, because they're not much to look at. If their ancestor had remained on the South American continent, birders wouldn't exactly be flocking to see them. 🧵🪶

A diagram shows nearly 200 circles, each labelled with a term for a distinct colour. A short description indicates that the frequency of each colour among the world's bird names is represented by the size of the circle.

A plumb, green bird rests on a branch. A green circle on the photo is labelled with the term "glistening-green".

A large, stocky gull stands on a rock. A grey circle on the photo is labelled with the word "glaucous".

A glittering purple and black hummingbird stands on a branch. A purple circle on the photo is labelled with the words "velvet-purple".

If you've ever wondered about the words we use to describe the colours of birds (who hasn't?) I've got all the answers you seek. Today on the blog: The Colours of the Birds of the World. Full-sized image available there. 🪶

The lesson, I figure, is that if you want to have it all you just need to do the opposite of what everyone else is doing and be prepared to look a bit weird. That started out as a joke but it actually sound pretty good. Go forth and be weird. What's the worst that can happen?

The Swallow-tailed Gull, with its big, googly eyes, is purpose-built for midnight snacking on the ocean's surface-feeding abundance. Fish and squid are on the menu, and with other seabirds handcuffed by their poor night vision, there's more than enough to go around. 👇

To resolve this, zooplankton - who eat phytoplankton - come to the surface at night, when the birds are asleep. Small fish and squid also visit the top floor to eat the zooplankton, so the ocean's surface at night is a seafood buffet with nobody visiting. Well, almost nobody. 👇

In the end, like all things in the ocean, it comes down to plankton. The ocean's surface is home to phytoplankton - tiny critters that make energy from the sun. Other tiny creatures want to eat the phytoplankton, but the surface is a place with many perils. Birds, for one. 👇

The world's only nocturnal gull is understandably a bit goggle-eyed in full-face. Those honkin' peepers are not unlike the ones you'd find in an owl's head, perfect for spotting prey in the dark. But what could entice this elegant bird to sport this oddball accessory? 👇

An elegant gull is standing on a rock facing sideways. It has long wings folded over its tail, a gently curving beak, and a handsome coat of soft greys.

The same gull stands on a rock, but this time facing the camera. Its eyes appear unusually large and forward facing, giving it a bug-eyed appearance.

In profile, the Swallow-tailed Gull is sublime. The soft gradients, the long wings, the gently curving beak, the tasteful pops of colour...it's a looker in side-view, no doubt. Head-on though, it's a total weirdo. 🧵🪶

Maybe the giant tortoises really have life figured out. Maybe you should climb inside a big cardboard box and breeze about the local park chewing on the greenery. It certainly sounds peaceful, if not entirely thrilling. Food for thought, I suppose.

With people everywhere trying mindfulness and meditation to cope with the chaos of the modern world, it's wild to imagine 55,000 consecutive days spent walking a few steps and munching some grass or a juicy cactus pad. No intrusive thoughts, just sleep, eat, repeat. 👇

I'm not one for buying into the hype, but standing in the vicinity of these big freaking turtles it's hard to deny just how cool they are. Their mystique is amplified by the fact that they can live well in excess of 150 years, albeit at a fairly tottering pace. 👇

If there's one thing everybody knows about Galapagos Giant Tortoises, it's that they're fairly large. Giant, you could even say. But knowing this simple fact in advance doesn't fully prepare you for the fridge-with-legs proportions of these ambling monoliths. 🧵

It's pretty weird to see penguins while you're sweating under the intense sun of the planet's waistline, but pretty cool (ha) too. The Galapagos seems to break all the rules. No complaints from our Quest Nature Tours group...bunch of rebels.

With no need for the heat-retention of a large body, the Galapagos Penguin has been allowed to become what scientists call "adorable", standing just half a metre tall. Otherwise they're pretty much regular penguins, doing penguin stuff like hunting fish and waddling about. 👇

Somebody once told you that penguins live in Antarctica, but they lied. Or, at the very least, they didn't tell you the whole truth. The diminutive Galapagos Penguin makes its home in the balmy waters of the equatorial Pacific, even occasionally ranging north of that imaginary line. 🧵🪶

Whatever the reason, I count myself lucky to have the opportunity to share space with these ocean-roaming giants, as did our Quest Nature Tours group in the Galapagos. There are many wonderful things in this spectacular place, but the albatross is a tough act to top.

I don't know what it is about albatr...these birds that speaks to me. Maybe it's their aircraftesque flight or their nomadic lifestyle. Maybe it's just how freaking big they are. Maybe it's that they're more cartoon than bird...the perfect fulfilment of my childhood fantasies. 👇
