Crows can make lightning-fast decisions, sometimes twice as fast as humans, clues show

Crows are intelligent animals that can use tools, hold a grudge And even organize funerals. New research suggests that these birds can make certain decisions more quickly than humans and monkeys – another potential sign of their intelligence, researchers say.

In a study published Thursday October 22 in the journal Scienceresearchers discovered that two carrion crows (Corvus crown) could distinguish the direction of moving dots on a screen in 235 milliseconds on average, or less than a quarter of a second. On the other hand, historical studies of humans suggest they make decisions in similar tasks six seconds faster.
