In 2002, four Baltic countries Estonia, Latvia, Lithuania and Sweden were issued a set of common designed stamps features four Baltic birds, when Estonia, Latvia and Lithuania were newly independent from former USSR. Four stamps are printed in intaglio and issued as booklet format. Four birds are commonly to be found in these four countries, Black-tailed Godwit breeds from Iceland to most of Europe, and also areas of Central Asia. The bird migrates to Australia, western Europe and western Africa in winter. Now Black-tailed Godwit classified as near threatened.
