Thank you Yumi for this great cover from Japan. Two bird stamps were used for postage. The Common Kingfisher one was issued in 2010 while the Red-crown Crane was issued in 1974 as a part of a set on Japanese folk tales.
Red-crown Crane (Grus japonensis): It is the second rarest crane in the world. It can be found in Siberia and northeastern Mongolia. In the winter it migrates to east Asia. It feeds on aquatic invertebrates, small amphibians, insects and plans which grow in swamps and marshes. It is an endangered species.
