The Potoos consist of grey, brownish and black color patterns. These live in tree barks and trunks. The interesting thing about these birds is that they sleep the whole day in a vertical form and usually wake up at night times. Their eyes are capable to see the insects in dark nights. They capture their preys especially the creeping and flying insects. These birds catch their preys with their long tongue and wide mouths. The whole process is very fast and it takes the Potoos only seconds to capture and digest their preys to get instant energy.
