Common Raven

Corvus corax

 

Glorified in traditional cultures worldwide, the Common Raven does not act by instinct alone. Whether tumbling aimlessly through the air, delivering complex, meaningful vocalizations or sliding playfully down a snowy bank on its back, this raucous bird demonstrates behavior many think of as being exclusively human. Few birds naturally occupy as large a natural range as the raven, but the Rockies remain one of the most reliable places in which to experience their habits. It seems that little goes on in the Rockies without the omnipresent raven surveying the scene.
