Everything in this diverse family from least weasels ("Mustela nivalis"), the smallest mammalian carnivore, to wolverines ("Gulo gulo"), the largest terrestrial mustelid, have turned up as prey in golden eagle nests. The members of this family which are most regularly hunted are probably the martens, such as the American marten ("Martes americanus"), pine marten ("Martes martes") and beech marten. The young of larger species are also occasionally hunted in Scotland and Ireland, including Eurasian otters ("Lutra lutra") and Eurasian badgers ("Meles meles").
