Antarctica: Outline of the trip
Written By robta on Saturday, August 11, 2012 | 8:55 AM
The vast majority of expedition cruises to Antarctica go from South America to the Antarctic Peninsula, and the map shows why. South America extends much farther south than Africa or Australia, and the Antarctic Peninsula is the northernmost point of the white continent, so the crossing is feasible for many kinds of ships. There are also some expedition cruises that go south from New Zealand and take in the subantarctic islands of that country, and a few cruises that go south through the bird-rich waters of South Africa to the continent's edge, and we would like to try those routes eventually. But so far, all five of my trips have originated in South America.
Most world maps (like the one above) show Antarctica as an ill-defined mass along the lower edge, so it's hard for most people to get an idea of the continent's size. Antarctica is huge -- near the size of Australia and Europe combined. It is roughly centered on the South Pole, and the interior of the continent is the coldest region on earth. We confess that, as naturalists, we're not very interested in visiting the South Pole; nothing lives there except a few dedicated scientists. Remarkably, the South Polar Skua has occurred there as a stray, having flown many hundreds of miles across lifeless ice and rock, but we'd rather watch birds like this out at the Antarctic coastline where they belong.

Antarctica: Day One, Pre-trip Birding in Ushuaia
Written By robta on Sunday, August 5, 2012 | 7:26 AM
We've already written about some of the birds we saw around Buenos Aires, and we saw more on the official pre-trip to Otamendi on January 5, but things really got underway on January 7th in Ushuaia. This city, located on the Beagle Channel in southernmost Argentina, prides itself on being at the "end of the Earth" -- or "Fin Del Mundo," as the signs say on the edge of town. Ushuaia has become a major stopover point for tourists, as almost all the cruises going to Antarctica make their turnarounds here.

Our friend, your friend, heck, it's everybody's friend, the Rufous-collared Sparrow.
The local American Robin look alike--the Austral Thrush. Kim loves the name of this bird. This is obviously a juvenile, all decked out and bedazzled with spots galore.


The act is getting classier. This beautiful bird is the Patagonian Sierra-Finch. It was all over the National Park, frequenting camp sites, looking for scraps left behind by campers. It reminded Kim of a Mourning Warbler at first glance.
This bird was, without a doubt, a highlight for everyone in the group! The Magellanic Woodpecker is a glorious looking bird. In the genus Campephilus (yes, the same genus as the Ivory-billed) one thing that's particularly fun about this species is that the female is the really gorgeous one in the pair. She sports this amazing top-knot with a forward-curving crest of slightly curled feathers. The photo is of the male, but we had stunning looks at the female too. A hell of a time for one's camera battery to go dead. Wouldn't you say?! [Kim's screams of frustration echo through the night...]
On the way back into town we stopped the bus in the middle of the street to enjoy watching a small group of Austral Parakeets. Clambering about and performing impressive acrobatic manuevers among the branches of the Southern Beech Trees, they were a blast to watch. Even if we had to perform our own acrobatic manuevers in the bus seats to get in position to take this photo.
Back into Ushuaia, we birded a series of ponds and coastal lagoons on the edge of the city. This Crested Duck was one of several species of waterfowl that we saw.
The lovely Dolphin Gulls were a nice change of pace from looking at Ohio's rather drab and homely Ring-bills and Herring Gulls. [Kim's thought...Kenn asks for a disclaimer here.] Not quite as sharp as Heermann's Gulls, but close.
You are one day closer to BABY PENGUIN PICTURES!
Update from Antarctica
Written By robta on Thursday, July 19, 2012 | 9:27 AM
Anyway -- It appears that we won't be able to attach any photos to this message, so we'll just have to paint a picture with words for the moment. Today (Monday January 19) we were at sea all day, cruising south from the South Orkney Islands toward the Antarctic Peninsula. We saw no land today, but we saw hundreds of icebergs, some of them huge towering mountains of ice, others great flat tabular bergs more than a quarter of a mile across. Birds were not as abundant today as on some of our previous at-sea days, but we saw flocks of Cape Petrels and Southern Fulmars, scores of Wilson's Storm-Petrels and Black-bellied Storm-Petrels, and various other birds. Beautiful snow-white Snow Petrels were flying around many of the larger icebergs, and late in the day we were visited by a few strikingly patterned, fast-flying Antarctic Petrels. Most remarkable of all was a lone Emperor Penguin swimming in the open water, all alone, miles from any land.
Despite seeing such amazing birds, mammals stole the show today: the ship was able to maneuver slowly and respectfully close to several Humpback Whales and huge Fin Whales, and we watched some distant Orcas (Killer Whales) late in the day. At one point, passing a large area of floating pack ice, we saw several Leopard Seals hauled out on the ice -- these big seals are fast-swimming predators, the terror of all the smaller penguins, and the ones on the ice stared at us as we passed, their large reptilian heads frozen in permanent evil grins. We expect to see more Leopard Seals tomorrow, patrolling the waters just off the big Adelie Penguin colony on Paulet Island.
Internet access out here at sea is sporadic at best, but we'll write again when we can. Eventually (after we're back in Ohio, maybe) we'll post a lot of photos from the trip, and more descriptions of the birding highlights.
Antarctica: Day One, Beagle Channel and Magellanic Penguins
Written By robta on Monday, July 16, 2012 | 10:50 AM

During the evening we were mostly admiring the scenery -- just as Darwin did when he arrived here in 1833 -- but of course we were also birding, and people who stayed on deck late enough saw the first penguins of the trip, the first of the eight species that we would encounter. These were distant views of swimming birds, and observers were startled to hear that these mysterious distant "ducks" or "grebes" were really Magellanic Penguins. The photos below were all taken a couple of days later in the Falkland Islands.

The first thing to notice in this close-up portrait is the color of the background: green. The public may think of penguins as birds of the deep-freeze zones, but Magellanic Penguin belongs to the genus Spheniscus, a group of four penguins that are all limited to mild climates. These are Galapagos Penguin on the Equator, Humboldt Penguin in western South America, Jackass Penguin (yeah, that’s one of its official names) in southern Africa, and the Magellanic, which is found all around the southern coasts of South America. The latter has several large colonies in Argentina, and seeing it in the Beagle Channel was no surprise.
The second thing to notice is that the bird has, let’s face it, sort of a slow-witted expression. Penguins aren’t at their best on land anyway, but Magellanics come across as rather dim bulbs.

As we would see on the Falklands a couple of days later, it’s a common thing to see Magellanic Penguins standing around peering at holes in the ground. But they have a good excuse: that’s where they nest. They’ll dig burrows up to six feet deep, laying their eggs in a cavity at the end of the burrow, and tending their young underground until the chicks are large enough to be safe from most predators. Penguins in the Antarctic nest out in the open, but several kinds in the temperate zone are burrow nesters.

Here’s an adult Magellanic Penguin peering out of its burrow. The striking face pattern is a lot less obvious once the bird is in the shadows, and it may serve as disruptive coloration, breaking up the bird’s outline and making it less conspicuous.

Zooming in and overexposing another shot of a penguin in its burrow, we can see a couple of chicks lurking in the background.

And here’s a better look at a slightly larger chick out at the entrance to the nest burrow with one parent bird. The chicks are fed by both parents for at least two months before they molt out of their fluffy down and go out to sea.
Antarctica, Day Two: I.D. At Sea
Written By robta on Monday, June 18, 2012 | 1:19 PM
So a day at sea, looking at challenging or tricky seabirds, turned into a wonderful ongoing discussion and series of impromptu seminars in birding. For me, with my long-time interest in advanced bird identification, and for Kim, who is interested in all of these things and who was seeing some of these southern seabirds for the first time, this was a day of total fascination. Some people might imagine that all those hours on the open ocean could become boring, but for a birder, nothing could be further from the truth.
Antarctica, Day Three: Punks and Saints
Written By robta on Thursday, May 10, 2012 | 12:07 AM
Ferried ashore in the Zodiacs, the sturdy inflatable boats that are a mainstay of adventure cruising worldwide, we got an eyeful and earful of wildlife on Saunders Island. This fabulous first stop presented a series of spectacles that kept us gasping with delight for the entire morning. Magellanic Penguins (about which we wrote in our post of Feb. 6) were in the water and on the beach, to be upstaged by hundreds of Gentoo Penguins and dozens of King Penguins. We’ll write more about those soon. But the star penguins of the day were the bold, weird little Rockhopper Penguins. We knew that Saunders would be our main encounter with this species, so we all spent a lot of time watching them.

Of course we shouldn’t assign human expressions to animals, but with the Rockhoppers it was almost impossible to resist the temptation. For example, we couldn't help wondering what this adult might be telling its fuzzy half-grown chick. 
Everyone on these Antarctic cruises is instructed not to approach the wildlife - - to stay back at least 15 feet from the birds (or farther for some species). But if you stand still, some of the birds will walk up to you. The Rockhoppers seemed curious, in a grouchy way, waddling up to members of our group and staring at them as if to say, "what the hell ... ?" 
("Hey, human chick, you wanna step outside and repeat that?")
Of course, once we were into this mode of anthropomorphizing (that is, applying human characteristics to animals), it was hard to get out of it. Nesting on the same hillsides as the Rockhoppers were colonies of Black-browed Albatrosses. We had seen many of these at sea the day before (along with lesser numbers of the much larger Wandering Albatrosses). But here we were able to watch them up close, tending their young, and we were struck by how they seemed gentle, benign, even wise.

Admittedly, the young were cute enough that they seemed worth guarding with care!
Maybe we can’t really tell what the adult albatrosses are thinking, but they do have beautiful faces. Can you deny the sense that these look like gentle giants?Antarctica vs. Galapagos: clash of claims
Written By robta on Saturday, April 21, 2012 | 1:15 PM
Adelie Penguins: Cool birds, but they're not in a biodiversity hotspotIt would be amazing, if it were true. But it isn’t true.
We live in an era when information can be flashed around the globe in an instant, perpetuated and multiplied a millionfold, whether it’s accurate or not. If it’s a remarkable piece of information and it seems to come from a reliable source, it will be repeated verbatim forever.
Here’s the background. Researchers from the British Antarctic Survey and the University of Hamburg carried out a detailed study of life on the South Orkney Islands and in the surrounding seas, down to a depth of 1500 meters. Between their own findings and a search of published records, they documented 1224 species of animals in the area, including five species new to science. All of this is very impressive, and the researchers are to be congratulated for their discoveries. It’s important for us to know that biodiversity at the edge of the Antarctic is higher than previously believed.
However, there was a problem with a press release from the British Antarctic Survey on December 1, 2008. This press release mentioned the Galapagos comparison just as a brief aside, but other news stories made this the headline. NewScientist presented it this way: "Antarctic islands surpass Galapagos for biodiversity." PlanetEarth Online said: "More Biodiversity in Antarctica than the Galapagos." Science Daily and LiveScience both said: "Antarctica Has More Species Than Galapagos." Dozens of websites, blogs, and newspapers repeated variations of the same.
It simply isn’t true, and I’ll give you the data in a minute, but it’s odd to me that so many news outlets repeated this uncritically. Certainly any birder on the news desk would have questioned it. After all, birders tend to be more aware of the realities of the world than most nonbirders. And I know I’m not the only birder who has been to both the Galapagos and the Antarctic.
Yes, the Galapagos Islands are arid and isolated. Diversity is not overwhelming there. Putting aside migrants and strays, the number of nesting bird species on the Galapagos is only about 60 -- but on the South Orkneys, the number is fewer than 20. What about insects? Birders often notice insects, if only for the fact that they’re often good bird food. The Galapagos have only about 400 species of beetles, to mention one insect group, but I guarantee that the South Orkneys have fewer than that. What about plants? After all, biodiversity involves all living things, not just animals. I don’t have figures for the South Orkneys, but it sticks in my mind that the number of flowering plant species on the Antarctic Peninsula is two. The Galapagos, arid and isolated though they are, have at least 550.
In fact, the figure given for the South Orkney Islands study, 1224 species of animal life, falls far short of what’s on the Galapagos. A study by Stewart B. Peck published in 1997 listed 1859 species of marine invertebrates in Galapagos seas, 2257 species of invertebrates on the islands and in fresh waters, and 431 species of vertebrates, for a total of over 4500 species. With new discoveries in the last ten years, the current number would be even higher. Add in the 1467 species of plants, fungi, and lichens listed in the Stewart Peck study, and the Galapagos are home to over 6000 known species of living things. The 1200-plus species around the South Orkneys are impressive, all right, but they don’t surpass the Galapagos.
Please understand that I’m not trashing the Antarctic region. The South Orkneys may have fewer than 20 species of breeding birds, but these probably add up to well over a million nesting pairs. Kim and I are leaving for the Antarctic in less than a month, and we’re insanely excited to be going. But I predict that ten years from now, people will still be repeating this false idea that the Antarctic has more biodiversity than the Galapagos, and I’ll still be wondering: How could so many news outlets repeat this without checking its accuracy?

This is a distant view of a tiny fraction of the King Penguin colony at Salisbury Plain on South Georgia Island. Look closely! Each little black and brown figure in this photo is a penguin! The brown ones are the big, fat woolly youngsters. They looked so much like bowling pins in fur coats! We saw tens of thousands of penguins on this trip, representing eight species, and we'll describe each species in separate posts after we get home.

Encounters with marine mammals provided some of the non-avian highlights of the trip. Whales, dolphins, and seals are all part of the Antarctic birding experience. Just wait until you see the Orca stuff we have to share!

It's going to take us a while to fully assimilate everything that we saw during the last few weeks, but we'll try to organize it all into posts on the blog so we can share what we experienced and we've learned about Antarctica with you.
