Sight
- The bald eagle's eyesight is three to four times stronger than that of humans.
- First, the eagle's eyes are so large that they occupy most of the space of its head. The large eye allows for a large retinal area where the visual image appears. Second, the eagle's eyes contain a high number of features which allow for visual accuracy and color perception.
- One more unique feature of the eagle eye is that the eagle has a second, transparent eyelid. This membrane protects the eagle's eyes from accidents when feeding young or catching prey.
Hearing
- The eagle's sense of hearing is comparable to that of humans.
Taste
- The eagle seems to have a less-developed sense of taste
Smell
- The eagle's sense if smell is poorly developed to the point where it can't detect strong odors under the snow.
Touch
- Its sense of touch is acute on the beak and feet, a feature that aids the eagle in capturing and killing prey. The bald eagle is well-adapted for hunting.
