Final answer:
The bald eagle is known for its distinctive dark brown body with a white head and tail; a color pattern that signifies maturity.
Step-by-step explanation:
The color markings that are likely to appear on the bald eagle are a dark brown body with a white head. Adult bald eagles are known for this distinctive color pattern with their white heads and tails contrasting against their dark brown bodies and wings. It is a sign of maturity, as juvenile bald eagles are mostly brown and do not develop the white head and tail until they are about four to five years old. These distinctive markings, along with their hooked yellow beaks, make them easily identifiable.
