Bird fortune telling

Is street bird fortune telling a skill?

Is street bird fortune telling a skill? Look at the following explanation:

You can be sure that this has nothing to do with fortune telling. Bird fortune telling is that those who train birds starve them for a few days and then put the feed in those paper piles, which can also be said to be signed. When birds get used to hunger, they will eat the feed in the sign. When the training is mature, they can go out with birds. Of course, they are not allowed to eat before coming out of the hole. Because there are signs of various years on the brand, when prospectors come to ask for testing, they will ask you what year it is. For example, if you say that you were born in 1983, he threw small feed into this constellation. Because there is little feed and the throwing speed is fast, birds eat it every day, which has long been seen by ordinary people. So on the surface, you can see that he reported the birth of a bird at 1983, depending on his fate. The bird seemed to understand, and immediately ran over and grabbed a brand from an 83-year-old man. In fact, it is really a god bird. It can understand people's language. Most importantly, for the fate of people born in all ages, autographs are completely extracted from books, and the simulation is ambiguous, which makes you feel as if it is really accurate. Of course, there are many tricks of bird fortune telling, not only this one, but also a new form.
