Species and people
Swamp owls can be called the most useful bird species, since, feeding mainly on rodents, owls destroy them in large quantities. Unfortunately, the plowing of meadows and steppes, as well as the drainage of swamps and floodplain meadows, deprives the owl of places suitable for nesting. Therefore, this rare endangered species is listed in Red Book in Ukraine.
A characteristic feature of the swamp owl is the method of creating a nest. It is located on the ground and is a trampled piece of land among tall grasses or dense shrubs.
