Owls( 猫 头 鹰 )are  active  mainly  at  night.They  hunt( 打 猎 )when  it's  dark. Most  of  us humans  go  about  our business  in the  daytime. So we hardly  ever  see  owls  during  the  day, but many of us like these night birds very much.

Our love for owls has a long history,and it's in all cultures.No matter how far you go back, there is always some type of artwork or story that is about an owl. These days, we find pictures of owls almost everywhere. So what is it about owls that makes them so popular?

Some bird researchers believe that  owls  are  popular  because  of their"cool"looks. In  order to see clearly in the dark, owls have large eyes. Unlike humans, owls cannot roll their eyes. Their  heads have to do most of the turning-around work. It's also for this reason that owls can turn their heads around almost entirely(完全地)on their necks.

Besides, another reason for its popularity is its ability to hunt.Owls use sound to hunt. Their ears are special—the left ear is a bit higher than the right ear. A sound goes in one ear before it arrives in the other. This helps owls tell which direction a sound is coming from.So they have a good sense of hearing.

Thanks  to  such  unusual  looks  and  abilities, owls  are  known  as  popular  animals. Over  the centuries, lots  of  stories  about  them  have  been  created. These  stories  have  made  more  people become interested in owls.
