A closer or focus video of a rooster crowing to show his dominance over his territory

This young rooster is crowing to show his dominance over his territory. His crowing indicates to other roosters that he is announcing that this is my territory. The alpha male will typically crow first followed by the lower ranks. So the crowing itself is basically a social ranking of the birds. It seems like it is from the bird kingdom such as these that we get the term “pecking order.” Essentially it is their place in bird society. In cases where people own two or more roosters on the same farm, the roosters will be crowing to each other all day long. It is to let the other one to beware that this is his territory while the other one is likewise crowing to stake his claim to the territory. If one of those roosters is removed thru natural death or being moved or whatever means, the lone rooster will hardly crow at all since he is already now the sole heir to the throne.
In this particular video there is only one rooster crowing to himself but if listen carefully you will be able to hear roosters crowing in the far distance. As he hears them crowing he likewise feels obliged to respond to them with his own crowing. They are basically announcing their presence to all comers that he is the reigning king of his area.
The other behavior that you see him doing is preening his feathers. This is typical of all birds. They have a uropygial gland that they squeeze with their beaks to secret oil which they then use their beaks to spread it over their feathers. The purpose of it is to clean their feathers of dust, dirt, bacteria, as well as to cause their feathers to be aligned and keep their feathers waterproofed.
