Bats have a vertical "blind spot" when using echolocation

As the article says, bats are known for their way to fly in the dark. They have the abilities to avoid obstacles while navigating even if they can't see where they are going. The bats send high frequency sounds which helps them to evaluate the obstacles. One day, Stefan Greif was studying the way bats use to go from place to another. He realized that bats had tendancy to collid with vertical surfaces. He decided to go further and do an experience. The results confirmed that bats have difficulty to recognize vertical surfaces. In nature, there are just a few surfaces that are apt to affect the bats path. Water is not part of the obstacles.

I chose this text because since I was a young boy, I have been going to my camp in the woods where there are many bats at night. A few times, somes of those collided in the wall of the camp. While reading the title of this article, I realised that this subject could interest me. I thought it would answer a few questions I had on bats.

This article is well written and interesting. It taught me that bats have difficulty recognizing vertical surfaces but I would have liked to know more about why it's like that.
