Eagle

Eagles are large birds of prey primarily found in Europe, Asia, Africa, North and South America, and, and are categorized under the bird family.

Eagles play an important role to the Assassin Brotherhood, in that many of the Order's outfits and weapons bear resemblance to eagles, and the birds swarm around View Points which the Assassins use to navigate their surroundings and perform Leaps of Faith from. In this regard, the Assassins dubbed the sixth sense that belonged to some of their members as "Eagle Vision."

History
Jupiter, a member of the First Civilization, wore a helmet that resembled an eagle. This became his representative animal when he was worshiped by the Greeks and Romans.

Altaïr Ibn-La'Ahad was named after the brightest in the  constellation; he acknowledged this by designing the door to his library to resemble the constellation. Only by placing the Memory Seal keys in the etchings of the constellation would the door to his treasure room open.

Ezio Auditore da Firenze collected eagle feathers for his younger brother Petruccio. After his death, Ezio continued to collect feathers in memory of his brother, placing them in a box in his mother's room at the Villa Auditore; this tradition continued following the siege of Monteriggioni, in a box at the Tiber Island headquarters.

The Kanien'kehá:ka revere eagles, and use their feathers in coming-of-age rites. During his coming-of-age, Ratonhnhaké:ton communed with Juno with a Crystal Ball, and the two spoke in the form of eagles. This conversation set Ratonhnhaké:ton on the path of joining the Assassins. The Colonial Mentor Achilles Davenport had a stuffed eagle preserved in his room on the Davenport Homestead.

In an alternate reality, Ratonhnhaké:ton underwent a vision journey where he communed with the spirit of the eagle, gaining the power to turn into one and fly short distances.
