Spotted by birder Steve Spitzer, the owl appeared to be 'swimming' in Lake Michigan. Another birder at Loyola Park Beach in Chicago says he saw the Great Horned Owl get apparently forced down into the great lake by two Peregrine Falcons.
Spitzer captured video and photos of the owl, but he didn't catch any of the falcon attack, as he and others at the beach were busy trying to scare the falcons away. Spitzer said bird rescue was called to the scene, but the owl flew away.
