There are 15 species of cranes that live across the world, but the rarest crane lives in North America. In 1941 only 22 wild birds existed as they were hunted for their feathers, and it seemed the Whooping Crane was effectively extinct. A group of passionate conservationists started a captive breeding program now there are about 600 Whooping Cranes in the wild. However, while there is progress, they remain on the Endangered Species List.
Our thanks to The International Crane Foundation for the great Whooping Crane call you can use as an alert or ringtone. We support their Whooping Crane Outreach Program.
