That was the nickname of Cubs great Lon Warneke.
He pitched for the pennant winning Cubs of 1935 and 1945, and would have been part of the 1938 team too...if the Cubs didn't trade him during the peak of his career.
Nevertheless, the Arkansas Hummingbird was one of the best Cubs pitchers of the first half of last century.

He was born this week in 1909.
