An avid bird enthusiast, Princess Takamado has championed the cause of avian conservation through her honorary presidency of BirdLife International, urging kids to get involved in the world of bird watching and establishing the Asia Bird Fund. In addition to her efforts on behalf of our feathered friends, she has spread the word about fragile ocean and Arctic environments through Lulie the Iceberg, a picture book for children about a breakaway iceberg’s adventure from the Arctic to Antarctica–complete with a companion musical score featuring famed cellist Yo Yo Ma.
