The rock pigeon is one of the invasive species in the world, partly because they have historically been used by sailors for navigation. When looking for the nearest land to dock, the captain would release a pigeon from the ship. If the pigeon returns, that means there is no land nearby. If the pigeon does not return, it means that the pigeon has found new land. As a result, pigeons, and not humans, are often the first to arrive in new territories.

In Taiwan, their droppings and feathers are seen as a health threat as they spread diseases. The rock pigeon also occupies the same foraging areas as the native spotted dove and competes with it for survival.
