Ravens are a small, common bird that can be found anywhere. They will eat berries, fish and feed from corpses but prefer not to eat cuts of raw meat. They are among the few wild animals that are not reluctant to feed from human corpses.
Actively hunting ravens, like most other small birds, is generally not a productive use of time unless one needs more feathers to make arrows or already has traps in place to catch them without taking too much effort.
Ravens will generally produce 2-4 lbs of meat depending on their size, 10-25 feathers and about 0.3 lbs of hairless hide for leather.
