London, March 19 (IANS): Researchers have found that the blue tit, collared flycatcher and pied flycatcher have the fastest eyesight in the animal kingdom, with their vision being more than twice as fast as humans. Thought to be the fastest of any vertebrate animal, their remarkable vision system, allows them to see the world around them in slow motion. “Bird species similar to the blue tit, collared flycatcher and pied flycatcher, both ecologically and physiologically, probably also share the faculty of superfast vision,” said lead researcher Anders Ödeen, lecturer at Uppsala University in Sweden. The study, published in the journal PLOS ONE, showed that perching birds, or passerines, have eyes with a temporal visual resolution -- precision of a measurement with respect to time -- of up to 146Hz.
