Ravens Give Wolves a Reason to Live in Packs | The Wolves and Moose of Isle Royale
The keeper of secrets and mysteries, the Crow/Raven is a totem that to the symbiotic relationship between the Raven (Crow) and the Wolf. The Wolf and Ravens - Very few mammals have symbiotic relationships with other animals. One of the few exceptions is the raven and the wolf. Ravens are. Keywords: Wolf-crow-Mongols-Turkic peoples-Romulus and Remus-animal .. the relationship between wolf and crow have been transmitted for a long time.
Ravens depend on the wolves to kill for them and open the carcass, but also to overcome their fear.
The Raven and the Wolf—a Study in Symbiosis
This strongly suggests an ancient evolutionary history, and ravens have been of great interest for centuries. In a sense, they are forming social attachments, as both form bonds with one another. When wolves stop to rest, ravens have been observed roosting in trees, where they can watch and harass the wolves at close range.
When this happens, wolves will resume travelling, which is most likely the intent of the raven to harass in the first place. Attractions Ravens are also attracted to wolves howling, as well as the sounds of gunshots. These are sounds to heed, which could well mean the presence of prey. When wolves get ready to hunt, they howl. Conversely, wolves also respond to certain raven vocalizations or behaviors that indicate the presence of prey.
Erev, or dusk, is the time when day mixes with night. In fact, the word for mixture in Hebrew is ervuv. Ravens are a mixture in that they are the only bird to possess two of the signs of kosher birds as well as two of the signs of non-kosher birds — a true mixture.

The Midrash notes that the raven also has a tendency to mix even when mixing is forbidden: Ham, the raven, and the dog. Perhaps it is for this reason that the chieftains of Midian are called Ze'ev and Orev by the Torah.
The crime of Midian was to send their girls to mix and intermingle with the Jewish People. Ravens and wolves are both creatures that represent dusk, the mixture of light and dark, and also mixing in general. Furthermore they mix with each other, mammal with bird. The dusky ravens and wolves of dusk are both symbols of the mixing of two distinct realms.
In a commentary to Exodus 8: Bernd Heinrich in "Mind of the Raven: Investigations and Adventures with Wolf-Birds" wrote: The wolves' howls before they go on a hunt, and it is a signal that the birds learn to heed.
Conversely, wolves may respond to certain raven vocalizations or behavior that indicate prey. The raven-wolf association may be close to a symbiosis that benefits the wolves and ravens alike. At a kill site, the birds are more suspicious and alert than wolves. This also turned out to be not quite right. Decades of observations on Isle Royale wolves showed, quite surprisingly, that as pack size grows larger, each wolf in the pack gets less food.
Although they kill moose a bit more frequently, larger packs have more mouths to feed. We began to wonder, could ravens help us understand why wolves live in packs?
Wolves are almost always followed by ravens - waiting to scavenge from the next kill. Typically, between 5 and 20 ravens attend a kill site.
Each raven can eat or cache about two pounds of food per day. Ultimately, ravens can scavenge as much as a third of what wolves kill. Perhaps wolves live in groups to reduce losses to scavenging ravens. Larger packs, despite the cost of sharing with more pack mates, might do better than smaller packs by minimizing losses to scavenging ravens.
Assessing this idea, would require accounting for how all the costs and benefits of foraging change with pack size.
After a great deal of calculating and figuring, it seems that ravens offer wolves a reason to live in packs. Wolves living in larger packs lose less of what they kill to scavengers.
