Humans and Human-Related Dangers
- Habitat destruction. The destruction of natural habitats due to urbanization and agricultural expansion reduces the availability of nesting sites and hunting grounds for barn owls.
- Pesticides and rodenticides. Barn owls can be indirectly affected by pesticides and rodenticides that reduce the populations of their prey or cause direct harm if consumed.
- Collisions with cars and trains. Barn owls fly low when hunting which makes them vulnerable to collisions with vehicles in areas.
- Trapping and shooting. In some parts of the world, barn owls are still trapped or shot for their feathers or because they are considered pests.
