Red Kite -- The Red Kite was saved from national extinction by one of the world's longest running protection programmes, and has now been successfully re-introduced to England and Scotland. I like the shift from orange to green.
"WWF's mission is to conserve nature and reduce the most pressing threats to the diversity of life on Earth." The World Wildlife Fund says it is a "nonprofit organization dedicated to environmental conservation through science." THey get new donations every single day and those donations can be a huge help to animals and the environment.
