City dwellers can attest that the animals they share the city with—the pigeons, rats, roaches—can be pretty brazen when they're prowling for a bite.
[by:可可英语～m.moreplr.com]

While visiting Barbados, McGill University neurobiologist Jean-Nicolas Audet, noticed that local bullfinches were accomplished thieves as well.
城市里的居民可以作证，与他们共同生活在城市中的鸽子、老鼠、蟑螂等动物在捕猎时非常厚颜无耻。

And we can see those birds entering in supermarkets, trying to steal food there. And that gave him an idea.
它们一直都在偷我们的食物。

Since this bird species is able to solve amazing problems in cities, and they're also present in rural areas, we were wondering are the rural birds also good problem-solvers, and they just don't take advantage of their abilities?
而且我们发现这些鸟会进入超级市场，试图偷那里的食物。而这给了奥德特灵感。

So Audet and his McGill colleagues captured Barbados bullfinches, both in the island's towns and out in the countryside.
或者这些鸟是因地区而完全不同呢?

assessing traits like boldness and fear, or timing how quickly the finches could open a puzzle box full of seeds.
而后他们对这种鸟的性格及智商进行了评估测试：

They were bolder, too, except when it came to dealing with new objects—perhaps assuming, unlike their more naive country cousins, that new things can either mean reward…or danger.
结果表明城市中的红腹灰雀能够更快的解决难题。

they have more robust immune systems, possibly from scavenging food and water in dirty places.
城市的红腹灰雀在另外一个方面也占据优势：

Which suggests that sometimes, a city's dirt and grit could be the very thing that gives avian residents a wing up.
它们有更强健的免疫系统，可能是其本身清除食物及水中脏东西的能力所致。
