Cinnamon Cockatiel - Nymphicus Hollandicus
Cinnamon cockatiels have grey-brown feathers instead of the dark grey feathers of a normal bird. Their eyes are
dark, and their beaks and feet are greyish. Cinnamon is a sex-linked mutation.
The song is vary from just a few notes to an elaborate
succession of musical phrases which can be quiet
complex, both melodically and rhythmically.
A native cockatiel's call is a loud, rolling "weero-weero".
