Scientists report that carrion crows make certain visual decisions roughly twice as fast as humans. Experiments present birds with moving dot patterns and require them to identify the direction of motion while researchers measure how quickly they respond.
Across the outlets, the focus is on speed and brain processing. One report describes the crows’ ability to rapidly analyze moving visual information, framing it as new insight into decision-making. Another specifies the experimental timing, saying crows take about 235 milliseconds on average to identify the direction of moving dots, while keeping accuracy high. The comparison also extends to humans and monkeys in the timing account, while other coverage emphasizes broader implications for understanding how fast animal brains can evaluate visual information.
