The eastern heather vole, (''Phenacomys ungava''), is a small North American vole. Until recently, this species was considered to belong to the same species as the western heather vole, ''Phenacomys intermedius''. It is also called the Ungava vole. Though some studies have indicated that ''Phenacomys ungava'' is "rare" or "uncommon," other researchers have found that the animal can be common locally, and others have suggested that the population may undergo cyclic abundance. ==Description== Eastern heather voles are relatively small among vole species, measuring from nose to tail and weighing between . They are very similar in appearance to the western heather vole, and can only be distinguished from them by subtle features of the coat color and the shape of the skull. The fur is long and soft. The coat is brownish with a slight yellowish wash over the back and head, with pale grey underparts and feet, and brighter, almost russet, fur on the rump and flanks. The face and snout of adults have a more pronounced yellowish cast, contrasting with the rest of the head and body. The tail is short, measuring about a quarter of the animal's total length, and is paler underneath than on the upper surface. The ears are very small, and barely visible above the long fur.〔 Males have scent glands on their flanks, which can reach up to across. Females have eight teats.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Eastern heather vole」の詳細全文を読む スポンサード リンク
