Why do Peregrine eyes look white?
Peregrines are actually equipped with three eyelids. The upper and lower eyelids are white; the lower one tends to close first. They also have a nictitating membrane – the third eyelid – that protects and moistens their eyes. Because it’s translucent they can still see when it’s closed.
Larger species of sharks (blues for instance) typically protect their eyes with their third eyelid when hunting and feeding. For birds, fast air currents can prove equally damaging. So, in birds of prey like falcons, the eyelid is used during rapid flight in hunting.

A peregrine falcon’s vision is eight times better than that of humans. They can spot small prey from 2 miles away. Falcons have three eyelids. The top and bottom eyelids are white. The third eyelid is a nictitating membrane(NICK-tih-tay-ting MEM-brane) that protects and moistens their eyes. It is translucent so they can still see when it’s closed. ...
Birds don’t have external ear structures like humans and other mammals. Their ear openings are hidden under the feathers on either side of their head. A falcon’s hearing is good, but not as strong as its sight, because it relies primarily on its vision to hunt. Falcons are silent while hunting, but make various sounds at other times. When bonding w...
Falcons don’t have a prominent nose like humans or other animals, but they do have nostrils (also called nares) on their ceres. Interestingly, they also have special nasal glands from which they sneeze out a mist of sodium chloride (salt) to help regulate the sodium and chloride content in their bodies, since they can’t get rid of it by urinating. ...
Falcons use their sense of touch quite a bit. They use their talonsto grip perches and prey, and even scratch an itch. They use their beaks to preentheir feathers, which means cleaning arranging, and oiling their feathers to keep them in good condition. They rub their beaks on an oil gland at the top base of their tail and rub the oil on their feat...
Additionally, peregrines have a third eyelid that clears debris from their eyes and protects their vision during flight and stooping. Peregrine falcons have nostrils that prevent high pressure from damaging their lungs during stooping. In fact, their nostrils were the inspiration for the first jet engine designs. 5.
Sep 27, 2023 · They have a Third Eyelid to Protect Their Eyes. Peregrine Falcons have a third eyelid that they use to protect their eyes while diving. This is called the nictitating membrane, and it acts as a protective barrier for the eye.
They have a third eyelid, which spreads tears and clears debris away to protect their eyes without obstructing their vision during a stoop. Peregrines can see most clearly with their head turned at an angle, which is why peregrine falcons usually fly towards their prey in a curve – this also helps them fly faster, as it reduces drag.
Jun 24, 2016 · The adaptation necessary to travel at these speeds is incredible: peregrine falcons have transparent third eyelids which effectively allow them to close their eyes against the wind and still see. Their nostrils have little cone-shaped, bone tubercles (or baffles) that limit the amount of air that can pass through ( click here for a closer look ).
