Female bald eagles weigh approximately 14 pounds with a wingspan of roughly 8 feet, while male eagles are slightly smaller weighing in at approximately 10 pounds with a wingspan of roughly 6 feet. Bald eagles are dark brown when they are young, and only acquire their bright coloring when they reach the age of 4 or 5 years.
Bald eagles have lifespans of approximately 15 to 25 years when they are in the wild, but they live even longer in captivity. Bald eagles lay anywhere from one to three eggs in a year, and each egg hatches within 35 days.
