Dove is the bird of the world. It's amazing that these pigeons are so bold and do not be afraid of your presence. This is not the first time that you share with us when animals are not afraid of you. For example, ponies that have recently become friends with you :)
Thanks to technological progress, people have learned to fly. But in our time we see a big technological leap. Quadrocopters are already being actively created for various purposes. There is a company that introduced the prototype of the first flying car. It works on electricity and therefore it can be called a big step forward. I am sure that in the not too distant future we will become witnesses of gradual changes.
Have a nice day
