About These Birds
Common Myna
The common myna has been named one of the world's 100 worst invasive species by the IUCN.

Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
