Crows make decisions twice as fast as humans and monkeys

University of Tübingen researchers have shown that crows, when confronted with a visual choice, make a decision twice as fast as humans and monkeys. In the experiment, two carrion crows took just 235 milliseconds on average to identify the direction in which a dot pattern was mov

Monarchs report their locations via… cellphone?

Who knew a monarch butterfly could borrow a cellphone to check in with friendly people he met on his journey? That is essentially what happens now that new technology has reduced the weight of a radio-pulse tag to less than half a gram (0.02 ounces).
