Songbirds are a universal symbol for happy news, especially if they are brightly colored and/or singing.
If they are flying, then your life is going to definitely take a turn for the better. Dead or injured birds, however, indicate either a halt to or a need to revise some of your plans for the future.
Birds of prey represent a warning: Someone is trying to take unfair advantage of you.
See “Eagle”, “Falcon”, “Hawk”.
Birds’ eggs in a nest indicate a new life full of hope – or this could possibly be a pun meaning money coming.
In other words, you’ll soon acquire a “nest egg.” An empty nest hints at a change of residence.
