What is chrismas island flag?

The Christmas Island flag features the familiar Union Jack in the top left corner, symbolizing the island's former status as a British colony, while the rest of the banner is taken up with a golden bosunbird in full flight. The bird, which is indigenous to Christmas Island, is a symbol of freedom, and its presence on the flag is meant to express the local people's love of liberty. The blue background of the flag represents the Indian Ocean, which surrounds the island. The flag was first adopted in 1986, to replace the previous design that had been in place since Christmas Island was granted self-government in 1978.
