Amazing sight of pigeons. Why do pigeons take off in front of a car rushing at them, it would seem, at the very last moment? In fact, as perceived by pigeons, the car moves much slower than it happens to us. This is explained by the fact that the pigeon needs to see about 75 frames per second in order to create the illusion of movement. If you put a pigeon in front of a movie screen, any film (24 frames per second) will seem to him just a set of slides replacing each other.
In addition, pigeons have another amazing feature of vision – they are able to see objects at a distance much greater than a person. This advantage of pigeons at the end of the twentieth century was appreciated by the US Coast Guard and began to use them in https://jiji-ethiopia.com/lideta/mobile-phones/apple-iphone-8-plus-64-gb-black-yntmCj7GAWBYnzx31gFjDupQ.html search and rescue operations. The pigeons were trained to distinguish between the colors of lifeboats and vests, then placed in a cage on the underside of a helicopter, into which each pigeon looked in one of the four cardinal directions. Upon seeing an object of the desired color, the pigeon only needed to peck at the button located next to it, which notified the pilot about the direction in which the drowning man was.
The keen eyesight of these birds helped them distinguish objects at a distance of three kilometers, while the human eye saw only a tiny speck in the distance.
