If a population of owls, generally not found in a community, moved into the community, several things might happen:
1. Competition for resources: The owls may compete with other species for food and habitat, which could lead to changes in the community structure.
2. Predation: If the owls prey on other animals in the community, it could lead to a decline in the populations of those species.
3. Disease transmission: If the owls carry diseases that are not present in the community, it could lead to the spread of those diseases to other species.
4. Changes in behavior: If the owls have different behaviors than the species in the community, it could lead to changes in the behavior of those species.
Overall, the introduction of a new species into a community can have complex and far-reaching effects on the ecosystem. It is important to carefully consider the potential impacts before introducing a new species.
