The raven is one of the principal birds of the Grand Canyon, known for its lofty aerial acrobatics and the clever raiding of backpacks for food. The raven is also regarded as having one of the finest brains of the bird world and a trickster’s sense of humor.

Ravens in research studies have established the ability to count objects up to the number six and have been observed using and altering tools to obtain food. Many a Grand Canyon visitor has discovered their ability to unzip zippers and pairs have definite territories they patrol as they wait for an unguarded food source. - Ds
