2 Dollars - Elizabeth II Cahow

The Cahow — properly the Bermuda Petrel, Pterodroma cahow — was presumed extinct for nearly three centuries after its decimation by early settlers and introduced predators. Its rediscovery in 1951 by naturalist David Wingate, who then dedicated over fifty years to its recovery, became one of the more remarkable conservation stories of the 20th century. The Bermuda Monetary Authority has drawn on that narrative repeatedly for its collector silver program.

Wingate's breeding colony on Nonsuch Island numbered fewer than twenty pairs at its nadir.
