On the 22nd of March an educational lesson "Our little winged friends“ took place in Marcinkonys Primary School. Directorate staff and volunteers told children about the most frequent visible and audible birds. They also showed how to make birds from paper. All together we made the group of birds. And waving with paper wings children announced about the soon comming spring. After the lesson all participants went outside to hang nesting boxes. This way we joined to the campaign "Ninety bird springs“. Nesting boxes were made by the staff of Dzūkija National Park. And the employees of Varėna Forest company helped us to hang them.
