Crows are intelligent animals that can use tools, hold grudges and even host funerals. Now, new research suggests these birds can make certain decisions faster than humans and monkeys — another potential sign of their smarts, the researchers argue.

In a study published Thursday (Oct. 22) in the journal Science, researchers found that two carrion crows (Corvus corone) could distinguish the direction of moving dots on a screen in an average of 235 milliseconds, or less than a quarter of a second. By contrast, historical studies of humans suggest they make decisions in similar tasks six seconds as fast.
