Birds fly in a circle because it conserves energy and provides them with a better view of their surroundings. When birds fly in a straight line, they have to constantly adjust their wings to keep themselves on course. This takes a lot of energy and can be tiring. By flying in a circle, they can maintain a consistent speed and altitude with less effort.
In addition, flying in a circle gives birds a better view of their surroundings. They can keep an eye out for predators and spot potential prey more easily. This is especially beneficial for birds that live in open areas, like grasslands or deserts.
So, the next time you see a bird flying in a circle, remember that it’s not just doing it for fun. There are some very good reasons behind this seemingly strange behavior.
