There are two types of Munias seen in North America. The Scaly-breasted Munia, once known as the Nutmeg Munia. It is a native bird of Asia, including the Indonesian and Philipines Islands. This mumia can be found in the southern regions of Caifornia.
The Tricolored Munia is also a native bird of Asia, found throughout its southern tropical countries.
Both these munias have been introduced throughout the globe. The Scaly-breasted Munia has established itself in Califonia, and their numbers are stable. The Tricolored Munia is seen in small numbers in southern Florida.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
