Recently, ravens have moved to our hilltop. They tend to prefer higher elevations, and 1800 feet seems to provide them with a hospitable environment.
I have been observing the crows in our woods for many years. While similar in shape and coloring, the ravens are dramatically different in size, call, and behavior. They are much larger, with a deep throaty call, and rather than flock, they are often in pairs.
With their huge size and obvious intelligence, it is no wonder they play a large part in Native American culture.
