Disambiguation: for the birds, please see Sand Martin and House Martin
The Martens constitute the genus Martes within the subfamily Mustelinae, in family Mustelidae. Martens are carnivorous animals related to weasels, minks and wolverines. Many are tree-dwellers, preying most commonly on squirrels. Their diet also consists of birds and eggs. Recent DNA research has shown that the genus Martes is in fact polyphyletic, placing Martes pennanti and Martes americana outside the genus and ally it with Eira and Gulo, to form a new New World clade.
