The eagle symbolises: freedom, community, opportunity, action, determination, vision, wisdom, liberation, inspiration and victory.
It is a powerful, high-flying and noble bird.
Ah ok, to me it meant something more in the patriotic kind off feeling. So I looked it up and there seems to be a duality in how the eagle sign is being used.

It might also have to do with the pose it holds as I do not associate the pose of the bird with freedom for example. But maybe I am alone on this:)
Thanks for clearing it up though!
