Indian Rose-Ringed Parakeet

There are four subspecies of rose-ringed parakeet, also known as the ring-necked parakeet. The Indian rose-ringed parakeet, also known as the Indian ringneck parrot, which we saw in Udawalawe National Park and Bundala National Park in Sri Lanka originated in southern India and now has feral populations around the world, including Australia, Great Britain (primarily around London), and the U.S. (with stable populations in Naples, Florida, Los Angeles and Bakersfield, California and Hawaii).

They are bigger than any parakeet I'm familiar with, and actually are a parrot.  They are sexually dimorphic. The male has a red and black neck-ring and the female and all juveniles either have no neck-ring, or have a shadow-like pale to dark gray neck-ring. They are a beautiful green color and have a bright red bill. They average about 16 inches in length, including their tail.

They are popular as pets (it is pets that have gone wild that have spurred their introduction around the globe) and can be taught to speak. Their is a blue morph which is popular in the pet trade.
