Where do ravens live?
At one time, raven populations in the eastern US drastically decreased because of the logging of old growth forests. Today they are making a comeback and are found in a variety of different habitats such as deserts, mountains, boreal forests and along coastal cliffs. Boreal forests are coniferous forests that are known for their long winters, short summers, and evergreen trees. Common ravens are found throughout the Border Country and also in Alaska, the western US, the Great Lakes area, the norteast, and the Appalachian mountains.

Did you know that ravens are extremely intelligent?
Ravens are known to find sick or dying animals and then to squawk to alert predators of their find. Signaling to the predators is advantageous for both the ravens as well as the predators. The squawking strikes the predators' curiousity and they will often wonder over and find the victim. Since the ravens are not able to kill large animals they rely on wolves, foxes, or eagles to do the job. Once the predator has made the kill, the ravens move in to take their share of the meat. Wolves have learned to fill up with all the food they can because the ravens will eat the leftovers.Ravens are even known to signal to people about a sick or injured animal.
Ravens sometimes "pick on" submissive wolves but they don't pick on high ranking wolves.
It appears that ravens can distinguish dominant wolves from submissive wolves. They seem to stay away from dominant wolves when they are feeding because they realize they are more likely to fight back. The ravens tend to swoop down and peck at submissive wolves when they are feeding to try and make them leave the kill.Next time you are in the woods listen for the loud squawks of ravens and maybe you can even follow one to see what the ravens have discovered!
