Ravens and wolves have a harmonious relationship.

So much so, that Ravens have been referred to as "wolf birds" by Native American tribes. This symbiotic relationship starts from a young age. Ravens can be seen playing tug-of-war with wolf cubs, nipping at their tails to get a rise out of them and flying low with sticks encouraging the pups to leap in an attempt to grab them out of the air.

Some ecologists believe that ravens will even form special bonds with individual wolves.

As the cubs grow, ravens become an integral part of the packs' hunting process. If ravens find a carcass that is too tough for their beaks to tear through, they will gift the carcass to their wolf pack. Ravens will also act as sentries around a fresh kill, alerting the wolves of hungry bear in the area.

To thank the ravens, the wolves will allow the birds to enjoy the kill along side them. As many as 135 ravens have been seen dining beside a wolf pack.

Not everything, it seems, needs to be treated as competition.
