Black-crowned Night Heron (Nycticorax nycticorax): The stamp was released in 2000. This medium-sized heron can be found almost anywhere expect Australasia and the coldest parts of the planet. It eats small fish, crustaceans, small birds, small mammals, frogs and aquatic insects.
Tundra Swan (Cygnus columbianus): It is the smallest of the holarctic swans and it has two subspecies. It can be found in Arctic and subarctic tundra but it migrates in marshlands and grasslands near the coast. It feeds mostly on aquatic vegetation.
