The Martens constitute the genus Martes within the subfamily Mustelinae, in family Mustelidae.
Their diet also consists of birds and eggs.
Recent DNA research has shown that the genus Martes is in fact polyphyletic, placing Martespennanti and Martes americana outside the genus and ally it with Eira and Gulo, to form a new New World clade.
