November 12 - Son's Day.
An environmental holiday, celebrated annually on November 12 at the initiative of the Russian Bird Conservation Union.
The date traces its history to the ancient folk holiday of Zinovi Sinichnik: our ancestors noticed that at that time wintering birds moved from the forests closer to human habitation in search of food.
On this day it is customary to prepare canteens for the birds, hang feeders and prepare treats - raw sunflower seeds, pumpkin seeds and unsalted pork fat.
