Smart, Social Animals
Recently, researchers have found that dolphins know their own names much like people. Dolphins talk to one another with whistles (口哨) and calls. Scientists have known that the animals also use unusual whistles to name each other. They had thought that dolphins only heard each other's voices. However, the scientists didn't know that dolphins listen for their names too.
To test this idea, the researchers caught 14 dolphins and recorded their name calls. The scientists then copied each dolphin's voice. When the changed recordings were played, the dolphins replied strongly to the names of their relatives and close group members. They paid no attention to the names of dolphins they did not know.
Dolphins live in large groups that grow and change. Each dolphin's unusual whistle helps it quickly find a friend or a family member, or call for help. Understanding their calls requires learning. It's a skill that's seen in very few animals, which include humans, elephants and bats.
Elephants, for example, communicate with sounds. Their sounds can be heard by other elephants miles away. Dolphins, too, communicate with each other by making sounds like this.
Elephants also communicate by moving their head, feet and trunk. In much the same way, dolphins communicate through their movements. They often touch each other to express friendship.
Unlike dolphins, elephants also communicate through their great sense of smell. They can recognize other elephants through the smells they have.
Why do dolphins and elephants share the gift of communication? Scientists think it may be because they are social and smart animals. Both have strong family relationship. Now, whether they also have nicknames is another question!

"Then how can you live happily all the time? Don't you think the mark makes you {#blank#}5{#/blank#}?" I asked.
"No, actually, the mark makes me special. I always tell {#blank#}6{#/blank#} that I have no way to decide what I look like, {#blank#}7{#/blank#}I can decide what I want to be. I'm much luckier than those that can't walk or run. At least I'm a healthy

Mike is a 13-year-old bird-watcher. He knows a lot about different birds. He can tell their different sounds. "I enjoy watching birds. I would like to know what kind of bird I will see after waiting for a long time," says Mike. Mike started watching birds in early 2020. His parents stopped the family's journey plans because of the virus(病毒). So he often watched the birds flying outside his window. "When you watch birds flying through trees, you will feel like you are one of them running after one another," he says. During his holiday, he often went with his father on birding journeys. He took many photos of birds on the tours and put them online. "Bird-watching is good for health. It is also the best way to get close to the nature ," he says. Now Mike is a student in Grade Seven. This term, he starts a bird club. More and more kids join the club. At the weekend, they often go to the park to watch birds. They write down information about birds when watching birds. "Bird-watching is easy because birds are all around us," says Mike. |
