How do eagles spot their prey from great distances?

Eagles have exceptional eyesight, allowing them to spot prey from distances up to two miles. Their eyes have a high density of photoreceptor cells, enabling them to detect fine details. Additionally, they have two foveae (central vision areas) in each eye, giving them binocular and peripheral vision simultaneously. Their large pupils let in more light, and specialised lenses focus precisely on distant objects. This keen vision is essential for hunting, as eagles rely on sight to locate small animals, fish, and birds from high altitudes.
