Invasive species around the world are threatening native birds by usurping food sources, taking over nesting sites or becoming predators in delicate ecosystems. Other threats, including pollution and habitat loss, are also increasing the numbers of endangered birds.
Fortunately, BirdLife International also have evidence that conservation efforts can be effective, and several bird species have been downgraded to less threatened status after habitat restoration measures. Educational programs also help raise awareness and can help protect critically endangered birds.
