Operation Migration

If you look up at the sky in the early fall in the northern part of North America, you may see groups of birds. These birds are flying south to places where they can find food and warmth for the winter. They are migrating (迁徙). The young birds usually learn to migrate from their parents. They follow their parents south, in one unusual case, however, the young birds are following something very different. These birds are young whooping cranes, and they are following an airplane!

The whooping crane is the largest bird that is native to North America. These birds almost disappeared in the 1800s. By 1941, there were only about 20 cranes alive. In the 1970s, people were worded that these creatures were in danger of disappearing completely. As a result, the United States identified whooping cranes as an endangered species that they needed to protect.

Some researchers tried to help. They began to breed whooping cranes in special parks to increase the number of birds. This plan was successful. There were a lot of new baby birds. As the birds became older, the researchers wanted to return them to nature. However, there was a problem: These young birds did not know how to migrate. They needed human help.

In 2001, some people had a creative idea. They formed an organization called Operation Migration. This group decided to use very light airplanes, instead of birds, to lead the young whooping cranes on their first trip south. They painted each airplane to look like a whooping crane. Even the pilots wore special clothing to make them look like cranes. The cranes began to trust the airplanes, and the plan worked.

Today, planes still lead birds across approximately 1,200 miles (1,931 kilometers), from the United States-Canadian border to the Gulf of Mexico. They leave the birds at different sites. If a trip is successful, the birds can travel on their own in the future. Then, when these birds become parents, they will teach their young to migrate. The people of Operation Migration think this is the only way to maintain the whooping crane population.

Operation Migration works with several other organizations and government institutes. Together, they assist hundreds of cranes each year. However, some experts predict that soon,this won't be necessary. Thanks to Operation Migration and its partners, the crane population will continue to migrate. Hopefully, they won't need human help any more.

On the Trial of the Honey Badger

On a recent field trip to the Kalahari Desert, a team of researchers learnt a lot more about honey badgers (獾). The team employed a local wildlife expert, Kitso Khama, to help them locate and follow the badgers across the desert. Their main aim was to study the badgers' movements and behavior as discreetly (谨慎地) as possible frightening them away or causing them to change their natural behavior. They also planned to trap a few and study them close up before releasing them in view of the animal's reputation, this was something that even Khama was reluctant to do.

"The problem with honey badgers is they are naturally curious animals, especially when they see something new. " He says. "That, combined with their unpredictable nature, can be a dangerous mixture. If they sense you have food, for example, they won't be shy about coming right up to you for something to eat. They're actually quite sociable creatures around humans,but as soon as they feel they might be in danger, they can become extremely vicious ( 凶恶的). Fortunately this is rare, but it does happen. "

The research confuaned many things that were already known. As expected, honey badgers ate any creatures they could catch and kill. Even poisonous snakes, feared and avoided by most other animals, were not safe from them. The researchers were surprised, however, by the animal's fondness for local melons, probably because of their high water content. Previously researchers thought that the animal got all of its liquid requirements from its prey (猎物). The team also learnt that, contrary to previous research findings, the badgers occasionally formed loose family groups. They were also able to confirm certain results from previous research, including the fact that female badgers never socialized with each other.

Following some of the male badgers was a challenge, since they can cover large distances in a short space of time. Some hunting territories cover more than 500 square kilometers.Although they seem happy to share these territories with other males, there are occasional fights Over an important food source, and male badgers can be as aggressive towards each other as they are towards other species.

As the badgers became accustomed to the presence of people, it gave the team to get up close to them without being the subject of the animals' curiosity - or a sudden aggression. The badgers' eating patterns, which had been disrupted, to normal.

"Lucky" Lord Lucan —Alive or Dead?

On 8th November 1974 Lord Lucan, a British aristocrat (贵族), vanished. The day before, his children's nanny had been brutally murdered and his wife had been attacked too. To this day the British public are still interested in the murder case because Lucan has never been found. Now, over 30 years later, the police have reopened the case, hoping that new DNA techniques will help solve this murder mystery.

People suspected that "lucky", as he was called by friends, wanted to kill his wife he no longer lived with. They say that Lucan entered his old house and in the dark, killed the nanny by mistake. His estranged (分居的 ) wife heard noises, came downstairs and was also attacked, but managed to escape. Seven months after the murder, a jury concluded that Lucan had killed the nanny.

What happened next is unclear, but there are several theories which fall into one of three categories : he may have killed himseff, he could have escaped or he might have been killed. It appears that the night after the murder, "lucky" borrowed a car and drove it. Lucan's friend Aspinall said in an interview that he thought Lucan had committed suicide by sinking his boat in the English Channel.

Another version of events says that "lucky" left the blood-soaked car on the coast and took a ferry to France. He was met there by someone who drove him to safety in another country.However, after a time, his rescuers became worded that they would become involved in the murder too and so Lucan was killed.

A further fascinating theory was made in the book Dead Lucky by Duncan Maclaughlin, a former detective. He believes that Lucan travelled to Goa, India, where he assumed the identity of a Mr. Barry Haplin. Lucan then lived in Goa till his death in 1996. In the end the claim turned out to be a case of mistaken identity. The man who died in 1996 was really Haplin, an ex-schoolteacher turned hippy. So what is the truth about "lucky"? DNA testing has solved many murder cases, but who knows if it can close the book on this one.
