Yes, pigeons can be considered an invasive species in many urban environments. Originally domesticated from wild rock pigeons, which are native to Europe, North Africa, and South Asia, the common rock pigeon has adapted remarkably well to city life.
One of the main reasons they are labeled as invasive is their rapid population growth and their ability to thrive in various habitats. Pigeons are highly adaptable birds; they can live in a wide range of environments and can find food easily in urban settings, which can lead to large populations.
In some cases, their presence can cause problems. They can contribute to the spread of diseases and can damage buildings and monuments with their droppings. This has resulted in local governments implementing measures to control their populations in densely populated areas where they may disrupt local ecosystems and affect public health.
However, it’s important to note that the perception of pigeons as invasive may differ depending on the region and the local ecosystem. Not all areas may experience negative impacts from pigeons, and they often cohabitate with humans without significant issues in many situations.
