Carl Jung said that birds represent thoughts while birds in flight symbolize moving and changing thoughts.
Birds are generally associated with freedom and abandon.
In old dream interpretation books, birds are considered lucky omens.
Doves and eagles are generally spiritual symbols.
Your dream depends on its details, but if the birds in your dream were flying free, it may be symbolic of spiritual, psychological, or physical freedom.
An eagle is a powerful bird and the unconscious message may be prosperity, success, and liberation from tedium.
The eagle is also a bird of prey and some negative connotations can be made. If the eagle is on the attack or the dream is frightening, reflect on your own aggressive and predatory thoughts and tendencies.
