What a poor name for a Warbler that is very common up here in northern Minnesota. The first person that recorded the bird species probably saw one in Nashville, TN and that was most likely the reason that it was named that way.
Vermivora ruficapilla is the binomial name and the first word Vermivora means “tree-dweller” and the species name of ruficapilla refers to the rufous feathers on the very top of the bird’s head. The rufous feathers are only seen when the bird is very excited when on its’ breeding grounds. Most of the time they keep those feathers well hidden.
