They live over 40 years and around 40 years of age, eagles go through a painful 5 month process of rebirth in which they remove and regrow their beak, talons and feathers thereby allowing them to live another 30 years.
Signets turn from gray to white at around 3 months of age. This change in color is due to the growth of new feathers that replace the downy gray feathers of a young signet.
