We spent two fascinating days at this wonderful place, and still didn't see everything! We took our time and absorbed the visions of animals in their almost-natural habitats. It was fun observing their behaviors, playing "Where's Waldo" trying to find the tigers and lions (who sleep nearly all the time), and picnicing out on the African plains.

We had the surprise bonus of being at the park during mating season--the perfect time to talk about mammal reproduction. It was a natural way to glide onto human reproduction a few weeks later at home. As parents, we were surprised at how easy this sometimes uncomfortable subject was to teach our children.

Its all about Habitats

This view of "East Africa" is a good representation of the kind of habitats that have been created at the Wild Animal Park (WAP). Though the cheetah couldn't get to the other animals, it seemed he was contemplating his next meal as he lounged. The WAP is a special place because they have tried hard to create natural environments for their animals. This has lead to a high birth rate among most of the species--something quite rare in captive situations.

The concept at Wild Animal Park is to put the people in the cages, as they ride around the park in the monorail cars.

Picnic in East Africa - by Amanda

We ate lunch while watching zebras, giraffes, rhinos and lots of other animals. It was almost like being in Africa.

After our picnic, I looked at baby rhinos with some binoculars. They were very cute!

Rhinoceros - Mammal version of Ceratopsian Dinosaurs

There are five species of rhinos: white, black, Indian, Javan and Sumatran. The word rhinoceros means "nose horn". They are the only living animals with horns on their noses. Unfortunately, their unique horns make them prized and hunted by humans. Because of this, all five species are very close to extinction. The Javan and Sumatran rhinos are among the most endangered animals on earth.

The Wild Animal Park has two kinds of rhinos: the white and the Indian. White rhinos are the largest of all land animals species, second only to elephants. They can be up to six feet tall at the shoulder, and weigh almost 8,000 pounds--as much as 50 men!

The skin of the Indian Rhino grows flabby, creating folds, and develops bumps. With the grey color, it looks like plates of metal armor with rivets all over. Although it isn't really armor, the Rhinos are very tough and can become angry very quickly.

A rhino's eyesight is poor, being very near sighted. Some scientists think that is why rhinos are so dangerous. Since they can't see far away, they charge at anything that may look threatening, like a jeep, or even a tree. A charging rhino can run up to 35 miles/hr. By the time the rhino gets close to the subject, it may recognize it to not be a threat, but it is too late....BASH! It is pretty hard to stop 6,000 pounds of charging rhino!

Evolution is pretty amazing, with the environment selecting which features survive. Rhinos fill the same kind of niche in the ecosystems today that the great ceratopsians (Triceratops) did in the Mesozoic period. It is no wonder that rhinos resemble ceratopsians both in look and possibly behavior.

Lorakeets - By Harrison

I got to feed some really cute parrots called Lorakeets. I fed them a special zoo recipe of nutritious nectar from a little cup. Feeding the lorakeets was like having bees buzzing around me and I stood totally still. I fed two lorakeets. I even got pooped on by the one that got on my hat. Luckily, when you buy the nectar, they give you some wipes!

Ruminants - by Susan

What are ruminants? They are cud-chewing animals, including cows, sheep, deer, goats, buffalo and antelope and other related species. Ruminants can take in large amounts of food quickly, so they are only exposed to danger from attacking animals while their heads are down. They can then find a safe place with a good view for seeing any approaching preditors, and work on digesting their load of grass.

They have 4-chambered stomachs: 1-the rumen (the fermentation chamber), 2-the reticulum, 3-the omasum, and 4-the adomasum (rennet stomach). They bring up a mouthful of grass from the rumen and chew it well, then swallow it and bring up another mouthful. As the grass passes from one stomach chamber to the next, it is broken down more and more by enzymes, until it is digestable.

We saw many types of ruminants at the Wild Animal Park, including these Thompson's Gazelles and Garanook (Giraffe antelope), where they had plenty of grazing and chewing space.

Zebras -by Harrison

Why the stripes? A leopard doesn't know the difference beetween greyscale and color. He confuses a zebra with the grass!

Are their stripes white on black or black on white? See the answer below.

Zebras are actually related to horses, too!

Gorillas - By Susan

Gorillas' skulls are larger than humans', but their brains are 1/3 the size. Their genes differ by only 3% from our own. Adult gorillas can't stand upright very long, but young ones have a lower center of gravity and can stand longer.

Gorillas belong to the ape family, which are all tail-less. Only monkeys have tails. Gorillas have bigger muscles in their arms than in their legs, and their arms are much longer than their legs. They are six times stronger than humans. Their hands are very human-like, complete with fingerprints.

They are choosy eaters, eating only the stalk of a certain kind of plant, or only the roots of another. They sometimes make neat stacks of the parts they don't want. They spend most of their time eating--up to 40 pounds of plants per day for an adult male. They rarely drink water, since they get so much moisture from the plants they eat. Their strong jaws are needed to grind up the tough plants.

Gorillas are gentle, peaceful creatures that only need adequate food to survive. They can only find the food they need in dense forests, which are being destroyed at a staggering rate. Gorillas are endangered, but most tragically the mountain gorillas. There are only about 400-600 of them living in a 285-square-mile area. Poaching also kills many of them.

Questions from our Visitors

Joann asks:
I would like to know if zebras are black with white stripes or visa versa. Most of my research shows that they have black skin and therefore are black with white stripes. My freshmen science students are trying to tell me that zebras are white with black stripes. Help!!

That was a perplexing question we had on our tour! The answer we got from one of the Park zoologists went like this:

"If you want to know if zebras are black with white stripes or white with black stripes, the answer is 'yes, they are.'"

The San Diego Zoo's spin-off "Zoobooks" by Wildlife Resources Ltd. states that they have black and white stripes. The belly of some species is white, suggesting that the background color is white, while a few have white spots or small stripes on a black background. There are even some individuals that come out all black or all white!

Scientists think that most ancestors of modern horses probably had some sort of pattern in their skin, which serves as a diffusion camoflauge to hide from preditors. It works sort of like a kaleidoscope. When the stripes of the zebra move among the tall grasses of the plains, the mixing image looks just like grass blowing in the wind, and makes it hard for a preditor to spot the animal.

Hope this answer helps!
