Does Golden Eagle migrate

Yes, first of all, not just that they migrate, in fact they migrate 2000 to 4000 miles. they have to start flying when they are 4 months old( born in may or early June) which is September or October, the main reason they migrate is to train their muscles ( this information not sure) and at last they spend winter at mountains far away then come back on spring which is like April then start mating, please thumbs up!
