1 . Like other penguins, African penguins have white feathers covering their chests and black feathers covering their backs. They have lifelong mates, and they live in huge numbers —so, scientists wondered how the birds were able to identify their partners among a sea of black-and-white birds. To find it out, they studied 12 African penguins at a marine park called Zoomarine Italia.
In one test, they hung two life-size photographs of the African penguins. One is selected randomly(随机选择地), while the other is the test subject’s mate. The scientists recorded their interactions with the photos: How long did they spend looking at each photo, as well as how much time did they spend standing near each one? The penguins spent more time looking at the photo of their partners—about 23 seconds longer, on average —than looking at the other photo. They also stood next to the mate’s photo for twice as long. Then, the researchers covered up the heads of the birds in the photographs, and the penguins still stayed near their partners’ photos.
In another experiment, the researchers hung up two photos of a bird’s mate —but, in one, they had digitally removed its spots(点). In this case, the penguin again spent more time looking at the photo with the spots. In the third experiment, the researchers hung two penguin photos with digitally removed spots—one of the test subject’s mate and the other: a random penguin. In this case, the penguins did not appear to recognize their partners—they spent almost the same time looking at or standing near both photos.
Together, the research results suggest African penguins are zeroing in on their partners’ spots and using them like name tags. Scientists say: “Our results prove birds recognize their mates by specific visual patterns and all sensory modalities(模态)should be considered in the study of animal communication.”

5 . It takes almost two years to grow a pineapple before it’s ripe and ready for harvest. For rubber trees, it can take at least six years before latex (橡胶) can be collected. So you could imagine the frustration and heartbreak of seeing the fruits of a farmer’s patience and dedication destroyed in a matter of minutes. This has been the cruel reality for those living around Kui Buri National Park, where some of Thailand’s largest populations of Asian elephants hang out.
For years, these farmers have worked hard to make a living from their crops, only to witness it all damaged under the footsteps of the wild giants. But the elephants are not to blame; with their usual feeding spots now changed into farmland, there is little left for them to eat — except the massive fields of tempting, easily accessible juicy fruits, all lined up like a continental breakfast buffet.
While she felt angry about her damaged crops, farmer Nichakan Pongsarikit saw an opportunity that the mighty creatures offered. Embarking on a journey to become a local guide, she began learning more about the animals and their behavior, movement, and habitat, along with foreign language skills, with the support of the Kui Buri Conservation Association and WWF-Thailand.
“I used to never want to encounter the elephants,” she said, now entering her seventh year as a guide. “Now I want to see them every day.”
Like her, other affected farmers have also found innovative ways to embrace the situation. Some are now making handmade souvenirs from elephant-related products, such as natural dye (染料) and ‘poo poo’ paper from elephant dung (粪便), and selling them to tourists who come to visit the elephants in their natural habitat. While it does not come without challenges, this transformation demonstrates the economic benefits that conservation could bring to communities, and the vital role communities play in conservation.

7 . Four Natural Wonders
Poás Volcano, Costa Rica
Sitting more than 2,707 metres above sea level, Poás Volcano has been active for hundreds of years. Visitors can still get up close and personal with it at the national park where it’s located (with a reservation).
Tips: Dress warm and bring an umbrella, as rainfall is common at the top of the mountain due to unpredictable weather conditions.
Mount Otemanu, Bora Bora
Mount Otemanu is the main attraction on Bora Bora, an island first made popular during World War I. The massive mountain, which stands 727 metres above the lagoon of Bora Bora, is now the perfect backdrop for dreamy Tahitian sunsets. A few of the luxury resorts on the island which offer great views of the mountain have become hot spots for honeymooners.
Grand Canyon, USA
Arizona has no shortage of impressive mountains and sweeping views, but the Grand Canyon is hands down one of the most diverse geological wonders in the state. Visitors have several options to experience the beauty here: adventure seekers can enjoy an aerial view from a helicopter ride through the canyons or go whitewater rafting down the Colourado River.
Cappadocia, Turkey
You may have seen fascinating photos of colourful hot air balloons against a magical landscape of rugged cliffs, valleys and towers carved into the rocks. It’s hard to believe this place is real but it is and it’s in Cappadocia! For a good position overlooking the landscape of this natural wonder, check out Uchisar Castle or ride during sunrise in a hot air balloon.
