These include "whinny" sounds, barks, buzzings, and clicks. The call is a slow whistled "ker-whee", or a descending whinny. Hwin's name brings to mind the word "whinny", a sound that horses make. He used the "horse whinny" at the beginning of Van Halen's 5150 song "Good Enough". He also had a wife, Elizabeth Whinny, who had four of his eight children.
