Hi! I’m Chiku, the chimpanzee. We chimps are champs at climbing trees—and much, much more. Keep reading and you’ll see.

Chimps are Champs, May 2010 Ranger Rick magazine  

Lucky me! I live in a big, beautiful African rainforest! I hang out here with my mom and my older sisters. From time to time, other family members and friends join us. Sometimes we gather in trees, and other times on the forest floor. Either way, we have a great time, eating and relaxing together. We chimps are champs at chillin’.

We’re winners at all kinds of play, too. Little chimps, for instance, like to roughhouse, wrestle, poke, and grab each other. We also do somersaults and spin round and round. Sometimes we laugh a lot — making chuffing or panting sounds. Other times, we play with pieces of bark or small branches, inventing games with these “toys.” Like your younger brother or sister, we may carry some of our toys around with us everywhere we go.

Snack Snaggers

We chimps are totally awesome at tracking down meals. The grownups in our family may spend six hours a day tromping through the underbrush or swinging through the treetops to find good eats. But find them, they do. Favorites are fruits, especially ripe figs. Mom also goes for green leaves and stems. I’m still nursing, so she just gives me little tastes of these treats every now and then.

Chimps also chomp on such things as seeds, blossoms, bark, bird eggs, ants, termites, and sometimes even small monkeys. So you see, we’re hardly picky eaters. If you invited us for supper, we’d probably clean our plates in no time — and then ask for seconds!

Up There — Where?

Trees can be great places to grab a bite. But that’s not all. They’re also perfect spots for snoozing. Every night, we chimps build nests of branches and leaves up in the trees. Then we settle in to catch some zzz’s. Best of all, trees are our very own jungle gyms. Right now, I’m just getting the hang of moving hand over hand through the canopy. But I’ll soon be going a little ape, swinging and leaping crazily through the branches like a real acrobat!

Chimps are natural champs at these high-jinks. That’s because we have super-strong shoulders and extra-long, flexible arms. (A chimp’s arms can reach the full height of a grown man.) Our thumbs also help us grip branches. So, all in all, life in the trees is easy.

Great Talkers

We chimps are amazing when it comes to communicating with each other. You should hear all the sounds we make. Like you, for example, we sometimes cry and whimper. And when excited, we let out a pant-hoot. That’s a loud, ear-splitting call that can carry about a mile through the rainforest. Each chimp’s panthoot is different. So we may not see who’s calling, but we can usually tell who it is!

Keeping Close

We show our feelings by touching each other. For example, when we’ve been away from our friends for a while, we greet them with hugs and
kisses — as you may do!

And two chimps often strengthen the friendly ties between them with another kind of touching called grooming. That’s when the chimps take turns picking dirt and pests out of each other’s hair.

That’s me in a quiet moment with Mom. Holding her hand makes me feel safe and peaceful.

Giving Comfort

Like you, chimps often turn to others for support. A nervous chimp may grab hold of a buddy. In fact, older chimps may each have as many as five close pals. The friends reach out to one another when they’re stressed. They also eat, travel, rest, and sleep near each other.

Of course, when little chimps like me are afraid, we turn to our mothers. After all, who’s better at making us feel that everything is all right?

Good Lookers

The expressions on our faces also tell other chimps how we’re feeling. That’s why chimps in a group constantly "read" how everyone looks to check out their moods. Our faces reveal many different emotions.

Free Riders

I think my mom is the champ of all chimp mothers! She nurses me, keeps an eye on me, and showers me with lots of affection. She also makes sure I’m learning all I’ll need to know when I’m grown up.

And if I’m not by her side, I’m almost always going along for the ride! Like all grown chimps, Mom walks on all fours, leaning on her knuckles. (Some people call chimps “knucklewalkers.”) But when she sets off somewhere, I don’t walk — I hop aboard my mother!

And take it from me, it’s a fun way to travel. When I was really little, I clung to Mom’s chest. But now that I’m a year old, I perch on her back like a jockey. Up here, I can take in all the sights. It’s relaxing, too. I often fall asleep to the gentle rhythm of Mom’s walking.

Chimp mothers seem to know the best ways to play with their babies. Here’s how it usually happens with me and my mom: She’ll be grooming me, and I’ll start acting silly. Then, before I know it, she’s tickling me. Soon, we’re into one big, squirmy-wormy, ticklefest! I’m giggling now, just thinking about it.

Bet you wish you could be a fun-loving champ of a chimp like me. Well, what’s stopping you? Go on—climb a tree, tickle a friend, give a hug. Oh, and don’t forget to laugh a lot!

Recent Chimpanzee Discoveries



  1. Young chimps have super-sharp memories. In a computer experiment, a young chimp could recall the location—and order--of numbers 1 through 9 that flashed only briefly on a monitor. Smart college students couldn’t do this anywhere near as well.
  2. Young chimps play with “dolls.” The chimps sometimes carry around rocks and sticks and may even cradle and groom these “dolls.”

  3. Chimps can think and plan ahead--by making complex tools. Scientists have known for a while that chimps were smart and could make tools. But recently, people have observed chimps using the most complicated, known tools ever made by animals, other than humans. For instance, in central Africa the animals have made a set of at least five different kinds of tools to get at underground honey.

  4. Chimps know when they need help—and who to pick as helpers. Chimps know when they need help from another chimp to solve problems, such as getting at hard-to-reach food. A chimp also remembers from their past experiences which among the group is the best at cooperating. So it goes and gets that helpful chimp for the task at hand. This is another sign of chimp smarts!

  5. Some male chimps woo mates in special ways. In one area, the males steal fruit from farms and orchards and offer it to nearby female chimps. The males appear to be showing off their food-gathering skills to the females—as a way to win them over.

  6. Chimps use gestures (pointing, mimicking actions) the way we do. People once thought that only humans used gestures or pointing to “say” something. But a chimp may scratch a certain spot in a loud, exaggerated way. This makes it clear to a nearby chimp, “I need you to groom me right here.”
