"On the Trail of the Buffalo", also known as "The Buffalo Skinners" or "The Hills of Mexico", is a traditional American folk song in the western music genre. It tells the story of an 1873 buffalo hunt on the southern plains. According to Fannie Eckstorm, 1873 is correct, as the year that professional buffalo hunters from Dodge City first entered the northern part of the Texas panhandle. It is thought to be based on the song Canaday-I-O. According to extensive research carried out by Jürgen Kloss in 2010-2012, this song is one of the many variants of John B Freeman's "The Buffalo Song".
