CHAPTER 9
Getting animals used to the presence of humans is at the heart of the art and science of zookeeping. The key aim is to diminish an animal's flight distance, which is the minimum distance at which an animal wants to keep a perceived enemy. A flamingo in the wild won't mind you if you stay more than three hundred yards away. Cross that limit and it becomes tense. Get even closer and you trigger a flight reaction from which the bird will
not cease until the three-hundred-yard limit is set again, or until heart and lungs fail.
Different animals have different flight distances and they gauge them in different ways.
Cats look, deer listen, bears smell. Giraffes will allow you to come to within thirty yards of them if you are in a motor car, but will run if you are 150 yards away on foot. Fiddler crabs scurry when you're ten yards away; howler monkeys stir in their branches when you're at twenty; African buffaloes react at seventy-five.
Our tools for diminishing flight distance are the knowledge we have of an animal, the food and shelter we provide, the protection we afford. When it works, the result is an emotionally stable, stress-free wild animal that not only stays put, but is healthy, lives a very long time, eats without fuss, behaves and socializes in natural ways and—the best sign-reproduces. I won't say that our zoo compared to the zoos of San Diego or Toronto or Berlin or Singapore, but you can't keep a good zookeeper down. Father was a natural.
He made up for a lack of formal training with an intuitive gift and a keen eye. He had a knack for looking at an animal and guessing what was on its mind. He was attentive to his charges, and they, in return, multiplied, some to excess.
CHAPTER IO
Yet there will always be animals that seek to escape from zoos. Animals that are kept in unsuitable enclosures are the most obvious example. Every animal has particular habitat needs that must be met. If its enclosure is too sunny or too wet or too empty, if its perch is too high or too exposed, if the ground is too sandy, if there are too few branches to make a nest, if the food trough is too low, if there is not enough mud to wallow in—and so many other ifs—then the animal will not be at peace. It is not so much a question of constructing an imitation of conditions in the wild as of getting to the essence of these conditions. Everything in an enclosure must be just right—in other words, within the limits of the animal's capacity to adapt. A plague upon bad zoos with bad enclosures!
They bring all zoos into disrepute.
Wild animals that are captured when they are fully mature are another example of escape-prone animals; often they are too set in their ways to reconstruct their subjective worlds and adapt to a new environment.
But even animals that were bred in zoos and have never known the wild, that are perfectly adapted to their enclosures and feel no tension in the presence of humans, will have moments of excitement that push them to seek to escape. All living things contain a measure of madness that moves them in strange, sometimes inexplicable ways. This madness can be saving; it is part and parcel of the ability to adapt. Without it, no species would survive.
Whatever the reason for wanting to escape, sane or insane, zoo detractors should realize that animals don't escape to somewhere but from something. Something within their
territory has frightened them—the intrusion of an enemy, the assault of a dominant animal, a startling noise—and set off a flight reaction. The animal flees, or tries to. I was surprised to read at the Toronto Zoo—a very fine zoo, I might add—that leopards can jump eighteen feet straight up. Our leopard enclosure in Pondicherry had a wall sixteen feet high at the back; I surmise that Rosie and Copycat never jumped out not because of constitutional weakness but simply because they had no reason to. Animals that escape go from the known into the unknown—and if there is one thing an animal hates above all else, it is the unknown. Escaping animals usually hide in the very first place they find that gives them a sense of security, and they are dangerous only to those who happen to get between them and their reckoned safe spot.
CHAPTER 11
Consider the case of the female black leopard that escaped from the Zurich Zoo in the winter of 1933. She was new to the zoo and seemed to get along with the male leopard.
But various paw injuries hinted at matrimonial strife. Before any decision could be taken about what to do, she squeezed through a break in the roof bars of her cage and vanished in the night. The discovery that a wild carnivore was tree in their midst created an uproar among the citizens of Zurich. Traps were set and hunting dogs were let loose. They only rid the canton of its few half-wild dogs. Not a trace of the leopard was found for ten weeks. Finally, a casual labourer came upon it under a barn twenty-five miles away and shot it. Remains of roe-deer were found nearby. That a big, black, tropical cat managed to survive for more than two months in a Swiss winter without being seen by anyone, let alone attacking anyone, speaks plainly to the fact that escaped zoo animals are not dangerous absconding criminals but simply wild creatures seeking to fit in.
