Sparrow nest on the balcony 🐦 This work has done my little cousin. He built himself a bird's nest, with straw in the middle, and fastened it to the steel of the balcony. In about 5-7 days a family of sparrows started living in that nest. There are currently 7-8 birds in this habitat, although there were many more birds in this bird family, they have left this family for the purpose of making new family. This is inner happiness to make others happy. This is how you can take birds in your balcony without buying them.
