When it comes to intelligence, human beings are the top dogs of the animal kingdom. But in recent years, scientists have been documenting surprising intelligence and emotional depth in animals ranging from honeybees to elephants. Here are some amazing examples.

Artistic Monkey Business

Jannet Schmid, director of the Little River Zoo in Norman, Oklahoma, learned a lot about the intelligence of capuchin monkeys. She and her busband adopted a young male, named Bailey. The capuchin particularly liked taking car rides, insisting that he insert the key and ride in the front passenger’s seat.

Now Bailey has become a devoted painter. He uses brushes to create colorful, abstract paintings, and prefers not to be disturbed.

Prairie Dog Sound

Through a variety of birdlike sounds, prairie dogs warn each other of approaching creatures. They demonstrated a surprisingly complex communication system. In his 25 years of study, Slobodchikoff, a professor of biology, has recorded them pronouncing ten nouns including hawk, deer and coyote, a number of adjectives to identify color, size and shape, and even some verbs to indicate speed.

In an ongoing study, Slobodchikoff learns that their brain contains a very extensive vocabulary. He once used his best prairie dog sound to say coyote, and they just looked at him in anger as if he had said a bad word.

Ivy League Parrot

One African grey parrot Alex is said to have the cognitive abilities of a five-year-old child. Alex can identify 50 different objects, seven colors, five shapes, quantities up to six, and the concepts of bigger, smaller, same and different.

Also Alex is considered to make reasoned decisions. During an experiment, researchers gave Alex different-colored blocks in sets of two, three and six. When asked which color group had five blocks, Alex replied, “None.” And he answered the same in repeated tests. Obviously, he interpreted the concept of “none” as an absence of quantity all on his own. That’s a lot like a high school student answering questions on a quiz show.
