（单词翻译）

 When you find yourself in a new town, you probably walk around it a few times in order to figure out where things are in relation to other things! In a little while it becomes easy. That process is sometimes called “constructing a cognitive¹ map.” Cognitive maps are just what they sound like: a mental version of the town you can consult in order to better get around in the real town. Now,here's a question.Do Birds Do This? Probably not, you might say. They’re just birds. But then, they navigate² very well. Maybe so! Does anyone know? Psychologist Alan Kamil of the University of Nebraska wanted to find out. He did some experiments on a species known as Clark’s nutcracker. These birds bury seeds for later, and show great ability at finding their stashes³ again from the air.
