“The researchers’ findings could ultimately help shape wildlife conservation practices. The paper notes, for example, that protecting smaller birds might be more dependent on creating environments that reduce human disturbance. The paper also suggested that ecotourism—which has been said to be dangerous to animal species in general—might be less harmful to larger birds than previously thought because larger animals are more likely to be able to tolerate human disturbance.” From: phys.org

The study reported in this article found that ecotourism is less harmful to larger birds. It didn’t find that ecotourism was not harmful at all.
