Numerous people reported a giant penguin seen on Clearwater Beach in 1948. The huge bird was described as 15 feet tall and supposedly left big tracks along the beach. During this same period, some people in a boat off the Gulf coast reported seeing an extremely large penguin-like bird floating on the water. These incidents were reported in several newspapers. In the same year, another big penguin-like bird was seen by a private airplane pilot on the banks of the Suwannee River in North Florida. The famed investigator of the unknown, the late Ivan Sanderson, conducted a scientific inquiry into both cases. No conclusion or explanation was ever reached.
