Indonesia uses the Garuda in a form called the "Garuda Pancasila" as its national symbol. It is somewhat intertwined with the concept of the Phoenix. The Garuda Pancasila is coloured black or gilded, symbolizing both the greatness of the nation and the "elang Jawa" (Javan hawk-eagle "Nisaetus bartelsi"). The black color represents nature. There are 17 feathers on each wing, 8 on the lower tail, 19 on the upper tail and 45 on the neck, which together make up the date 17 August 1945, when Indonesia proclaimed its independence. The shield it carries bears the motto "Panca Sila", which symbolizes self-defense and protection in struggle.
