10. Invasive Birds
Invasive birds are species that cause issues for human health, agriculture, and wildlife. Typically, an invasive species is one that is not native to a particular area and is threatening its balanced ecosystem. Not all birds that are non-native are invasive; many can adapt well to new environments without causing damage.
When an area has become drastically impacted by a bird species, that species is labeled invasive. It’s possible for a species to be in basics in one region and not in another. At that point, it would be simply called non-native. Common examples of invasive bird species include the European starling, mallard, mute swan, Canada goose, and house sparrow.
