As a symbol, a hawk represents the Heavens; power; royalty, nobility. It is similar to the eagle. A hawk can also be the symbol of Horus. (Some say he has the head of an Eagle, some say it is the head of a hawk.)
In shamanic tradition, Hawk -like the crane- is the Messenger of the Gods, akin to Mercury or Hermes. "Hawk medicine teaches you to be observant in everything that you do. Life is sending you signals. Life is the initiation."
If hawk appears to you, "then right now a clue about the magic of life is being brought to you. This magic can imbue you with the power to overcome a currently stressful or difficult situation. The test is your ability to observe the nuances of power lurking nearby. Is power the talent you have, and are not using? Are solutions always hard to find because you have lost the broader vision of Hawk? Or is Great Spirit displaying a gift that you need only to receive? Have the colors of morning inspired you to create? Or has the gloominess of a present situation left you Earthbound, unable to hear the voice within the raindrops splashing on your window? Pay Attention! You are only as powerful as your capacity to perceive, receive and use your abilities.
Hawk people see the overall view. Hawk people are aware of Omens, messages from the spirit.
You are to be aware of signals in your life - so notice and receive them. Hawk may be teaching you to grab an opportunity which is coming you way. On the other hand, Hawk may be bringing you the message that you should circle over your life, and examine it from a higher perspective. From this vantage point you may be able to discern the hazards which bar you from freedom of flight. Remember, Hawk has a keen eye and a bold heart, for hawk flies close to the light of Grandfather Sun." (Jamie Sams and David Carson, The Medicine Cards)
