The Monkey the Forest Hid for Twenty Years

Professor Pip trotted along a misty forest path, tail swishing, his big brass magnifying glass held up like a knight's shield. "Follow closely, my fellow scientists!" he called. "The forest is full of clues today."

Mia and Leo padded behind him, peering through cardboard-tube binoculars they'd made that morning.

"Clues to WHAT?" whispered Leo.

"To a monkey," said Pip, eyes twinkling. "A monkey the forest kept hidden for almost twenty years."

"Twenty years?!" gasped Mia. "How can a monkey be lost?"

Pip stopped at a fallen log. From one bulging pocket, he pulled out a stack of dried leaves. From another, a chart with lots of little monkey sketches on it. "Aha! Here's the trick," he said. "Every animal on Earth has a name — a species name. Scientists give one to every kind of creature so they can talk about it. But you can only give a new species a name if you're POSITIVELY sure it isn't just another kind we already know."

He laid ten leaves in a row. "Sort these into piles that look the same."

The children got to work. SNIFF, RUSTLE. Nine of the leaves went into one pile. But one leaf, a smaller one with a tiny orange dot on its edge, went into a pile by itself.

"THIS ONE'S DIFFERENT!" Mia announced.

"Precisely!" cried Pip, clapping his paws. "That is exactly what scientists do with animals. They compare fur, faces, bones, calls, and even DNA. In a huge national park in the Congo called Lomami, a team took a photo of a small black monkey way back in 2008. But they weren't sure it was a NEW kind. So year after year, they collected more photos. More facts. More clues."

He held up his magnifying glass. "And here's the special clue — a bright pinkish-cream patch of skin all around its mouth, like a little dab of ice cream. No other colobus monkey has that. Its closest cousin lives more than a thousand kilometers away!"

"Oh!" said Leo. "Like when we found the button in the sofa that didn't match ANY of our shirts!"

"Curiouser and curiouser!" laughed Pip. "Exactly right. Local people call it likweli — that's its everyday name. Scientists just gave it its official name: Colobus congoensis."

He looked up at the swaying canopy. "There may be fewer than a thousand likweli in the whole world. Which means we've found them just in time to help protect them."

He handed each child a tiny pocket notebook. "Now you try. Go home, watch a creature in your backyard, and write down FIVE things about it no one else has noticed. That's how discovery begins."
