Although you will find the definition of a Yellowhammer is a species of bird also known as the Northern Flicker, which is the state bird of Alabama, there are other defintions to the word. Patrick D. Smith wrote in a "A Land Remembered" that Yellowhammer, as the settlers of old Florida called them, were wild bulls which orginated from Spain and inhabitated Florida's once wild wilderness. Old Florida settlers found these bulls in palmetto thickets and cypress swamps and discovered them to be more fast and agile than regular bulls such as livestock. They were mostly unsuccesful in capturing these "Yellowhammer," which remained wild and free in the most secluded wildernesses of old Florida.
