Epilogue: Last Chance to See

     When I was in the Galapagos, I brought Douglas Adam's Last Chance to See along with me. The book details some number of trips he took in the late eighties to see nine charismatic species on the brink of extinction: Aye-ayes of Madagascar, Komodo dragons on the island of Komodo in Indonesia, the Kakapo in New Zealand, Mountain gorillas and the Northern white rhinoceros in Zaire, the Yangtze River Dolphin in China, the Rodrigues fruit bat on the island of Rodrigues, Mauritius (The same island the famed Dodo hailed from), Amazonian manatees in Brazil, and the Juan Fernández Fur seal on the Juan Fernández Islands, Chile. Not only were his journeys a way for him to see these critically endangered species: they were a way for him to travel all over the world and get a feel for what their habitats were like.

Very different, I suppose, than they are today.

     I'll admit that a great part of my motivation for travel this year was to establish the most intact 'baseline' I could for Central and South America. For those of you unfamiliar with that terminology, a 'baseline' is roughly defined as the sense of intactness of an ecosystem for the people who experience it. What follows is a concept referred to as a 'shifting baseline': what people consider to be a 'normal' environment or ecosystem is based on their personal experience, and changes with each generation as environments degrade and disappear. If you want to hear more about stories concerning shifting baselines, here's a funky podcast called 'Wild Ones'. I'm glad that I got to establish my baselines for the places I visited in Latin America when I did: they will undoubtedly be very different in ten, fifteen, or twenty years down the road when I can establish myself there to work in conservation for the rest of my life.

     Adams is one of my favorite authors. It was fascinating to read about his take on the travel and efforts involved to find and protect these species, especially given his lack of experience in biology. More fascinating, in sometimes heart-breaking, sometimes heart-soaring ways, were the comparisons I was able to draw between the conservation status of these species and their habitats in the eighties and today. The Echo, or Mauritius Parakeet, and the Kakapo are conservation success stories of our age; the Northern white rhinoceros is functionally extinct in the wild, with only three known individuals outside of captivity---seven in total, and only four young enough to breed. It is speculated that this particular species will go the way of one of its brothers: The Western black rhinoceros was declared extinct in 2013. 


The last sighting of a Yangtze, or Baiji, River Dolphin was in 2002. Adams couldn't even find one when he visited. The chapter is powerful: Adams and crew go about exploring what sounds polluted the river, as the Baiji dolphin was extremely sensitive to sound and dependent on underwater vocalizations to breed; the river was a screaming static. Boats, industry, and man-made river-walls had drowned out the dolphins. 

     Adam's stories may focus on these nine charismatic species, but his message and observations go much further: into the past and future of the environment that brought forth these fantastic creatures, which other irreplaceable flora and fauna are at risk, and what our relationship and responsibilities are to these places and animals, as humans and co-habitants of this planet.
Because it's so apropos, I wanted to share the short story Adams shared in the epilogue of his book here on my blog. It's called...

Sifting Through the Embers
by Douglas Adams

      There’s a story I heard when I was young that bothered me because I couldn’t understand it. It was many years before I discovered it to be the story of the Sybilline books. By that time all the details of the story had rewritten themselves in my mind, but the essentials were still the same. After a year of exploring some of the endangered environments of the world, I think I finally understand it.

     It concerns an ancient city – it doesn’t matter where it was or what it was called. It was a thriving, prosperous city set in the middle of a large plain. One summer, while people of the city were busy thriving and prospering away, a strange old beggar woman arrived at the gates carrying twelve large books, which she offered to sell to them. She said that the books contained all the knowledge and all the wisdom of the world, and that she would let the city have all twelve of them in return for a single sack of gold.

     The people of the city thought this was a very funny idea. They said she obviously had no conception of the value of gold and that probably the best thing was for her to go away again.
This she agreed to do, but first she said that she was going to destroy half of the books in front of them. She built a small bonfire, burnt six of the books of all knowledge and all wisdom in the sight of the people of the city, and then went on her way.

     Winter came and went, a hard winter, but the city just managed to flourish through it and then, the following summer, the old woman was back.

“Oh, you again,” said the people of the city. “How’s the knowledge and wisdom going?”

“Six books,” she said, “just six left. Half of all the knowledge and wisdom in the world. Once again I am offering to sell them to you.”

“Oh yes?” sniggered the people of the city.

“Only the price has changed.”

“Not surprised.”

“Two sacks of gold.”

“What?”

“Two sacks of gold for the six remaining books of knowledge and wisdom. Take it or leave it.”

“It seems to us,” said the people of the city, “that you can’t be very wise or knowledgeable yourself or you would realise that you can’t just go around quadrupling an already outrageous price in a buyer’s market. If that’s the sort of knowledge and wisdom you’re peddling, then, frankly, you can keep it at any price.”

“Do you want them or not?”

“No.”

“Very well. I will trouble you for a little firewood.”

She built another bonfire and burnt three of the remaining books in front of them and then set off back across the plain.

      That night one or two curious people from the city sneaked out and sifted through the embers to see if they could salvage the odd page or two, but the fire had burnt very thoroughly and the old woman had raked the ashes. There was nothing.

Another hard winter took its toll on the city and they had a little trouble with famine and disease, but trade was good and they were in reasonably good shape again by the following summer when, once again, the old woman appeared.

“You’re early this year,” they said to her.

“Less to carry,” she explained, showing them the three books she was still carrying. “A quarter of all the knowledge and wisdom in the world. Do you want it?”

“What’s the price?”

“Four sacks of gold.”

“You’re completely mad, old woman. Apart from anything else, our economy’s going through a bit of a sticky patch at the moment. Sacks of gold are completely out of the question.”

“Firewood, please.”

“Now wait a minute,” said the people of the city, “this isn’t doing anybody any good. We’ve been thinking about all this and we’ve put together a small committee to have a look at these books of yours. Let us evaluate them for a few months, see if they’re worth anything to us, and when you come back next year, perhaps we can put in some kind of a reasonable offer. We are not talking sacks of gold here, though.”

The old woman shook her head. “No,” she said. “Bring me the firewood.”

“It’ll cost you.”

“No matter,” said the woman, with a shrug. “The books will burn quite well by themselves.”

So saying, she set about shredding two of the books into pieces which then burnt easily. She set off swiftly across the plain and left the people of the city to face another year.

She was back in the late spring.

“Just one left,” she said, putting it down on the ground in front of her. “So I was able to bring my own firewood.”

“How much?” said the people of the city.

“Sixteen sacks of gold.”

“We’d only budgeted for eight.”

“Take it or leave it.”

“Wait here.”

The people of the city went off into a huddle and returned half an hour later.

“Sixteen sacks is all we’ve got left,” they pleaded, “times are hard. You must leave us with something.”

The old woman just hummed to herself as she started to pile the kindling together.

“All right!” they cried at last, opened up the gates of the city, and let out two ox carts , each laden with eight sacks of gold. “But it had better be good.”

“Thank you,” said the old woman, “it is. And you should have seen the rest of it.”

She led the two ox carts away across the plain with her, and left the people of the city to survive as best they could with the one remaining twelfth of all the knowledge and wisdom that had been in the world.

    Remember how I talked about the Brazilian Amazon in my summary post? Between Iquitos, Peru, and Manaus, Brazil--even beyond--you can fly in a plane and see -no trace of man- for many hours, in every direction. We're losing that forest faster and faster with each year that passes; the Western black rhinoceros, the Golden Toad, Hawaiian honeycreeper species; our bees, even. Chytrid fungus is wiping out an unprecedented number of amphibian species, white-nose fungus is killing American bat species, vultures in India have declined to almost 5% of their original population numbers because of poisoning from a commonly employed cattle sedative. Many people are realizing that climate change is the biggest threat facing the planet as we know and love it; we're watching the books burn faster and faster every year.

So. When will we pay up?

What will be our ending balance? Three volumes--two volumes? One volume?

None?

There's a lot of Amazon left. There are many, many species we could still save. And many we have started to. Humans are the most beautifully complex, wildly capable, and fascinating species on this planet; but we're just one of billions. We, unlike many of the others, have the power to care for the world around us. And we should be doing quite a bit more of just that.

The New Zealand Kakapo. 

Let's start paying up today: we'll cherish the volumes that we've saved tomorrow more than any gold.

Cheers,

Las Islas Galápagos y Parque Historico de Guyaquil

Captain's Log for May 3-6: AND FINALLY, with two weeks left in Ecuador, and the arrival of the next Aviary intern, Kristen Tobin, quickly approaching...I fled to the Galapagos. Eight plus years after my ninth-grade biology teacher gave me the Voyage of the Beagle, I made it to Darwin's islands, found Darwin's finches, and extensively questioned all the guides and scientists I ran into. I knew the Galapagos had world-famous ecological wonders, but man, I was still knocked flat at every turn. Swimming with the golden rays and marine iguanas, rapt with attention as the guides rattled off the subtleties of Darwin finch identification tricks, gleeful with my first encounters with albatrosses, flamingoes, and penguins in the wild...it was a biologist dream-cation. On my way back from the islands, I passed through Guyaquil and visited the historical area, where they have an awesome wildlife park...

Galapagos animals, conservation, and adventure. GO.

You can fly out to the islands on two national airlines in Ecuador. They're about five hundred kilometers offshore. 

Picture.
Me being me, I was ECSTATIC over the chance to see Darwin's finches. Talk about celebrity status: these little guys helped bring about the theory of evolution. 


I was also in love with the Lava Lizards. There were a few species on the islands: the females were more brightly colored than the males. 
Lonesome George: they've made him into a clothing company. meep.

I stayed in a hostel on Santa Cruz, in Port Ayora. This is the most heavily visited area in all the Galapagos: super touristy, with nightclubs and restaurants galore. There are ferries and boats that leave for the other islands from this port every single day, and often there are cruise ships docked in the harbor. 

Yellow warbler. 

Large-billed flycatcher. 


The lava and the mangroves: sea lion napping sites.  

The MARINE IGUANAS. They're awesome, and they're everywhere. They forage on the marine alga: males tend to be the only ones that dive to forage, while the females wait for low tide.  

"I think we're being watched..."

Sally lightfoot crabs. Such color. 


Awesome brine-water fissure on Santa Cruz: the terrain varied incredibly from dry forest in the island highlands to volcanic craters and tunnels on Floreana and Isabela; mangrove forests and rocky outcrops for bird nesting, brine or freshwater filling canyons like this one, and a number of small ponds and lakes inland. 

Male lava lizard!

Check this out: a bunch of marine iguanas come ashore at this site on Santa Cruz every afternoon. 

They 'sneeze' to expel the saltwater they consume while foraging, and are often salt-stained. So many! Lounging all over the beaches. 

Nice camouflage, guys. 

Lava heron....or just a morph of the striated heron? YOU decide. 

Inland marshes and pools. 


Galapagos mockingbird on Isla Santa Cruz. 



Great Frigatebird! Much like the Magnificent Frigatebird. Frigatebirds rock. 


Isla Floreana. 


There are twelve Galapagos-native finches and three others spread across the islands. They are relatively drab, but differ drastically in beak shape and size---and sometimes foraging strategy, as is the case with the 'Vampire' or sharp-beaked ground finch, which feeds off of the external parasites and blood of other Galapagos shorebirds. Their variations are what got Darwin musing about evolution. 


The highlands of Floreana. The islands are quite large!

Similar to the endemic finches, there were originally eleven species of galapagos giant tortoises: one for each of the volcanoes around the island. With the death of Lonesome George, there are only ten species remaining, and many of them are critically endangered due to hunting and trafficking. 

The way that they are trying to help these threatened populations is through breeding programs on Santa Cruz, Floreana, and Isabela. The turtles are closely kept and placed in breeding corrals on these islands, where they are reproducing at much faster rates. Members of the Environmental Ministry of Ecuador and these breeding centers hope one day to have the populations stable enough to re-release the turtles into their natural habitats at the base of the volcanoes where they evolved. 

The experiences with these breeding centers really got me thinking hard about how desperate our measures need to be to save these creatures now, and how tourism, though detrimental to these areas, is necessary if we want to prevent their utter destruction. 

For now, the support of visitors is enabling these breeding and conservation programs to move forward with superhuman efforts to save these incredibly iconic species...and tourism is crucial to the future of the Galapagos. 

Marine Iguana lounging on Playa Negra, Floreana. 

I love this: they call sea urchins 'sea hedgehogs' in Spanish. Erizos del mar. This is a sea urchin skeleton. 


Marine snails.

Sleepy sea lions everywhere. 

I wish I knew more and could tell you about all the amazing fishlife I came in contact with while snorkelling. The underwater sounds of sea turtles chomping down on plants and alga, their beaks clicking, was particularly delightful. 

Isla Floreana.

If you can focus on the rocks beyond the boat, there are Galapagos penguins, which are endemic. My first penguins in the wild. 

Hey there, cuties. There aren't many of them on Floreana; we got lucky. 

The Winged albatrosses, storm petrels, and other pelagic seabirds were incredible when seen taking off above the waves between islands. It took us an hour and a half to two and a half hours to reach Isabela and Floreana; I didn't visit San Cristobal, rumored to be the most beautiful, or Espanola, where the Albatrosses court and breed this time of year. 

Lava gull. 

Outdoor foodstands, or Kioskos, on Santa Cruz. 

They sold slipper lobsters for ten bucks apiece. I'd never seen these guys before; so weird without claws!

Winged Albatross nesting....in a picture on a calendar in my hostel, because you can only reach Espanola via cruise ship. SIGH. 


Isla Isabela had some increeeeeedible snorkelling. Saw a set of twenty-some sea turtles resting on the ocean floor at one point; felt like the marine iguanas meandering around near me swam like crocodiles. 

Blue footed boobies!


Great Blue Heron. 

Crazy lichens on island lava fields; TONS of lava lizards. 

More Galapagos Penguins! They swam RIGHT UP to us...

Brown Pelicans. Always awesome. 

More lava lizards...so pretty...

Pencil urchin. 

Iguanas nested on the outer edges of Isabela: a lot of the habitat was off-limit to visitors. 

A wild and sad story: the Mangrove Finch is now much like many of the turtles; being sequestered on other islands to save the species. The decline of Mangrove Finches, native to Isabela, is due to a parasite that eats mucosal membranes, rendering the finches unable to eat. There is a ton of research and work being done on this phenomenon at the moment...conservation medicine. This is what it's all about. 

Watching for reef sharks in a fissure on the edge of the island. They like to come into protected areas to eat developing fish. 

Some crablife. 

HERE'S A FISH PICTURE. Because my camera can't go underwater with me. 


There was a small man-made lake on Isabela where a handful of Greater Flamingoes were feeding. 

Amazing: these guys must have flown their way to the islands at some point in the past. Greater Flamingoes. 


There were also some White-cheeked Pintails here!


More turtle breeding centers. 




Banded birds! They're monitoring the Isabela Mockingbirds. 


Volcanoes supporting different giant tortoise populations. 



Logo gets to the point, I suppose. 

Always birdwatching...



On Santa Cruz, they had an admittedly fascinating, and questionably ecologically sound practice: they turn on the docklights at night, which attract swarms of fish...and thus rays, sharks, and sea lions. 


Even some pelicans were poaching late-night snacks. 

Cute little reef sharks. 

Port Ayora lit up at night. 

And sea lions. 





Yellow Warblers. 

On my last day, I took a walk through some dry forest with a guy who definitely knew his finches. The field stations on Santa cruz were asking for people to contribute any underwater photos of sharks they had in order to bolster datasets for behavioral research. Yay citizen science!

The Islands. Santa Cruz is the largest one. 


Really cool cacti and very different plants: sadly, it was pouring rain in the dry forest, and I didn't get many pictures. 

Male vegeterian finch!

Traps for invasive wasp species along the path. Nice. 

Protected turtle nesting areas. 



Finches eating skin and external parasites off marine iguanas!

Mmmm....iguana skin. 

Hermit crabs. 


SUPER POISONOUS Manzanillo trees. 

...the giant tortoises can eat the fruits, though. 

The home of the late Lonesome George: the turtle breeding center in Darwin Station on Santa Cruz. 




Apparently, giant tortoise females can store sperm up to three years to optimize the time they lay their eggs. Because of this, the two females of similar species they tried to hybridize with George before his death are still isolated at the breeding center. 

Success is baby tortoises. They have many. 

Funny side-story: I met a bunch of sperm whale biologists working with Dr.Hal Whitehead, from Del Housie University in Nova Scotia. I got to go see him speak, and hang out with them for a night. Yay biology!

Dr.Whitehead himself. 


Annnnnnnnnd they collect whale stool samples to analyze diet. Field biology is the craziest.

Me with the whale field crew!

On my last morning, I visited 'Los Gemelos'--two MASSIVE volcanic craters. It was incredible how much of the Galapagos I didn't get to see in my four short days there...I would definitely return. 


Until next time, Galapagos...

Visited the Historical Park in downtown Guyaquil. They have a similar setup to Amaru: a natural zoo-type display and educative materials about the rescued animals they care for. 


I have to say, the historical park was by far the most natural and most beautiful wildlife park I've ever been to. 






It was also, coincidentally, the first and only place I've seen Harpy Eagles in real life. 


They have a magnificent, three-story tower near the expansive aviary they have for their NESTING PAIR. I stayed up here for the better part of an hour. 

Harpy Eagles have the craziest calls: they sound like chickens, sometimes---othertimes as mournful as Common Loons. They're fantastic creatures. 















Pacific parrotlets nesting in telephone poles! Yeee. 

Took the bus back to Cuenca. The area around Guyaquil is truly fantastic; and so fun to see the coast fade to Andes. 

Quite the adventure. 

Cheers.
-A very happy biologist, NB
