About These Birds
pygargue à tête blanche
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
Common Myna
The common myna has been named one of the world's 100 worst invasive species by the IUCN. Originally from South Asia, it has been introduced to tropical regions worldwide where it outcompetes native birds for nest cavities. Despite its invasive status, the myna is an intelligent and charismatic bird capable of mimicking human speech.
