A ranger is humanoid. It is an omnivore.

"Lonely men are we, Rangers of the wild, hunters-- but hunters ever of the servants of the Enemy; for they are found in many places, not in Mordor only.

If Gondor, Boromir, has been a stalwart tower, we have played another part. Many evil things there are that your strong walls and bright swords do not stay. You know little of the lands beyond your bounds. Peace and freedom, do you say? The North would have known them little but for us. Fear would have destroyed them. But when dark things come from the houseless hills, or creep from sunless woods, they fly from us. What roads would any dare to tread, what safety would there be in quiet lands, or in the homes of simple men at night, if the Dunedain were asleep, or were all gone into the grave?" The Fellowship of the Ring, by J.R.R. Tolkien
