垃圾箱“爭奪戰(zhàn)”

何高倫

生活在澳大利亞的一些城市的鳳頭鸚鵡已經(jīng)學會了如何打開垃圾箱的蓋子，并在垃圾箱中翻找食物。

1 Cockatoos are large white birds in the parrot family. Theyre common in western Australia， where they normally live in wooded areas. But as forests have been cut down， cockatoos have gotten used to living near people.

2 Last year， scientists at the Max Planck Institute reported that cockatoos had learned how to open the lids （蓋） on trash bins. Thats not an easy job. The cockatoos must lift the heavy lid with their beaks and then walk along the trash bin， pushing the lid up until it falls over.

3 Cockatoos open the lids to find food. But they can also make a big mess， which upsets the people who own the trash bins. What really interested scientists was that the birds were teaching other cockatoos how to do the same thing. When scientists first began studying the cockatoos in 2018， only three areas near Sydney had lid?opening cockatoos. A year and a half later， cockatoos in 44 different areas knew the trick. Scientists were also studying humans. They asked over 1，100 people from around Sydney about their trash bins. More than 15% of the people were taking steps to keep cockatoos out of their trash bins.

4 Scientists spent weeks studying more than 3，200 trash bins in four different areas of Sydney. They wanted to see how many trash bins were protected， and what methods were used. The most common way of protecting the trash bins was putting a brick or other heavy objects on the lid. Humans were teaching each other tricks， too. In most neighborhoods， many people used the same cockatoo?stopping methods as their neighbors.

5 Its like a race between humans and cockatoos to learn new ways of doing things. Now many cockatoos have learned how to push heavy items off the trash bins. As a result， humans have figured out ways to attach （把……附） the items to the top of their trash bins. Scientists describe the situation as a “human?wildlife conflict”. They expect these conflicts to become more common as humans take over more areas that used to be wild.

6 Dr Klump says she hopes studies like this will lead to a better understanding and more patience with “the animals we share our lives with”.
