Antarctic Peninsula from Astrolabe Island

The seal has not been out drinking. His seemingly bloodshot eyes are not the result of excess. Like us, all seals must hold their breath when they dive. Because they dive so much deeper and longer than us, they have to supersaturate their blood with oxygen and it is that oxygen that reddens the blood and in turn reddens the eyes. Color tells you nothing of this animal’s emotional state or level of stress.

The Ol’ Red Eye

We tend to look for gross cues from wildlife. If they growl, we get it: “Too many, too close, or both – go back the way you came!” Except by then it is usually too late. In the case of this particular seal, his still and direct stare was his “growl.” To the seal this was as loud and clear as he needed to be, a sign in 3 foot letters.

Wendell Seal Takes A Backwards Look

It’s not just that we ignore the cues. We want to get too close. Why? Because we are so much alone here. And the soft thick fur and cat-like face of the seal only add to the force of attraction. It is not a trivial need. Companion animals even lower our blood pressure. Imagine then, the state of human well-being in a world without wild animals. It will be a state of perpetual aloneness of a kind we may not be able to endure.

How to get there:

I found the weddell seals in these photographs on Astrolabe, a small island off the Antarctic Peninsula. My fieldwork there and throughout the Antarctic was made possible by One Ocean Expeditions. They can get you there, and back.

Black-browed Albatross

West Point is a small island at the tip of the West Falklands. There, upon the high cliffs that rise like insurmountable steps, and inland among the rolling hills of tussock grass strange bedfellows nest. The cliffs are in the possession of a colony of Black-browed Albatross. No one else can get there.

The Place where only Wings will carry

In the tussock grass is where Rockhopper Penguins nest, the slope down to the sea at an angle just low enough that they can just barely, hop and scramble their way up several hundred vertical feet to build their nests and breed, and daily, hop back down again to feed. But wings will take you where feet cannot and in among the penguins pockets of the albatross. Because there is nothing to stop them.

Neither species much cares for this arrangement. The greatest fliers and the greatest swimmers here argue over space and the mud and straw with which they build their cup-shaped nests. Loudly. Incessantly. They lock bills.

They cry out.

Rockhopper Penguin Vocalizing

The sense of desperation conveyed is real. Both species are in decline. Fishing nets entangle the great wings of Black-browed Albatross. Fishermen steal the food on which Rockhopper Penguins depend. The climate itself is changing, and this also works against the birds. Faced with an ever warming ocean, the fish are moving south in search of cooler water. And at the base of the food chain, the krill are in serious decline. Many species of penguin depend directly on the krill, but now, so do men. Among others, Norway and Japan are already harvesting krill in quantity, and the Chinese are about to launch the largest krill processing boat in the world, crushing the source of life at its source.

Hard times ahead for everyone.

What you can do:

Call, email, write or visit the embassies of the countries with the largest take of krill, namely, Japan, South Korea, China, and Norway (contact information below). Ask them to please reconsider the harvesting of krill. Go to your local health food store and urge them to stop carrying fish oil products made from krill. While your there, find out who produces krill-based fish oil and call them too. And please let me know how it went, MSL(at)MarkSethLender(dot)com.

Reticulated Giraffe Lying Down

A herd of giraffe consists of a group of adult females and their offspring, or a group of males in a bachelor herds of their own. Individual males are only occasional visitors to the female herds. Although a herd of impala might run to 30 individuals or more, the largest herd of giraffe I’ve ever seen had 11 members with 5 to 7 animals being closer to the norm. There are many reasons for this but one stands out. When acacia trees (the giraffe’s preferred food) are over-grazed they produce toxins in their sap that are distributed by the capillaries into the leaves. Worse, a tree under attack somehow messages the other trees in the vicinity, so that if one acacia in a stand goes “sour” the others will follow suit. Exactly how this is accomplished is not known but giraffe are well aware of it. They nibble only a little, and move on. Obviously, the larger the herd the more impractical this strategy becomes. Too much browsing and palatability will set a limit much before the total number of trees and leaves. Another contribution to small herd size is the long gestation period of giraffe. They just don’t reproduce that fast. Plus, unlike most ungulates, newborn giraffe are slow to gain independence. There is just too much to learn. Namely, how to feed, where and how to drink and when it is safe to do so, and – for the young males – how to compete for females.

Giraffe defend against predators by kicking. You do not want to be kicked by a giraffe. Neither would another giraffe, so keep from killing each other they engage in what is called “Necking,” in which they swing their heads and slam each other with their ossicones, the horn-like structures on their heads. Pushing against each other is another form of competition and applies much the same logic as Necking: Weight wins.

Elder Brother & Little Man

What then to make of the two young giraffe I call Little Man and Elder Brother? The mismatch in size is obvious and therefore, the outcome of any contest a forgone conclusion. Why go through the exercise? The simplest and therefore the most likely interpretation is that this was a Teaching Moment

In the wild, weight and physical size matter almost more than anything. The biggest male lions are the masters of both their prides and the hunting territories those prides control, just as the heaviest elk is the one most likely to prevail in a clash of antlers. In a catfight between cats of different species (cheetah versus lion for example) a cheetah has a stark choice: Run or Die. Some of that is jaw strength, and there is also age and experience to consider; in all, weight is the trump card. Personality of the individual can inflect the outcome, but cannot conquer size.

Elder Brother as well as weighing half again as much as Little Man was also three heads taller, creating a substantive advantage in reach and leverage as well as throw-weight. Little Man not only lacked impact, he could not deliver his blows to the right places, especially when striking across the back of Elder Brother because his neck was not long enough to get there. This was a contest of No Contest. Yet Elder Brother showed great restraint and perseverance. Every move Elder Brother made was repeated many times by Little Man and there was no reason other than a desire to show him “how” for Elder Brother to allow it. He may have had a degree of benefit from what you might call “target practice,” but this alone does not and cannot account for the space and time Elder Brother gave Little Man to try. Elder Brother’s perseverance becomes a de facto transfer of knowledge and experience.

Getting there:
I flew to Kenya on KLM from JFK via Amsterdam to Nairobi. Donald Young Safaris picks its clients up at the airport (which is a huge help). They then either drive you to your destination or you can fly directly from Jomo Kenyatta International Airport. The flights are short, and comparatively cheap, about $250 per person each way. The drive is about four hours to the areas where the company has a large and elegant house (at El Karama) or luxury tents (in the northern Maasai Mara). If you want to see the towns (and I would recommend it at least one way) the drive is worth the trouble. One word of caution, in that it can be a dusty ride and if that is a concern you are probably better off flying. The experience at the end of the road or just off the airstrip as the case may be will be life-changing. A trip of 5 days duration plus a day each way for travel is the minimum I would recommend. In that time, with two game drives a day, you can see an amazing amount of wildlife. All-inclusive, trips are about $850/day plus airfare. Booking well in advance I was able to find a flight with KLM, JFK to Nairobi via Amsterdam, for about $1000 a round-trip. Don’t let the low fare dissuade you, my three favorite airlines by the way are Iceland Air, Norwegian, and KLM.

Donald Young and Newland, Tarlton & Co.
The giraffe in this story live in 15,000 acres of private reserve in Kenya, called El Karama. I was the guest there of Don Young, at Kiota House. Don also served as my host throughout the Maasai Mara. Every place he took me, over the two weeks I spent with him, was replete with wildlife. He freely shared his bottomless knowledge of Africa (people, places, animals) and if that were not enough he is a raconteur of African stories in the grand tradition. Don also has a great crew. Traditional Maasai, they are well-paid and treated with great respect (something that is not always the case in Africa), and their familiarity with terrain and an impeccable eye mean that very little wildlife is missed. They are a pleasure to be around.

If there is only going to be one wildlife expedition in your life, do this one. I cannot recommend it highly enough.
