First of all, birds should create safe living conditions in gardens and parks: do not disturb them (especially during the nesting period), do not destroy the nests, do not touch the chicks. You can attract birds by hanging nesting boxes and other artificial nests, planting trees and shrubs in cities where birds can hide from danger and build nests. In winter, it is important to help the birds feed by creating feeders for them.
