Caspian Tern (Hydroprogne caspia)

Issued in the 1970s as part of Qatar's Birds definitive series, this stamp commemorates the Caspian Tern (Hydroprogne caspia), the largest tern species in the world. Found along coastlines, estuaries, and inland waters across several continents, the Caspian Tern is a migratory bird that also occurs along the shores of the Arabian Gulf. The series was issued to showcase notable bird species and to promote interest in ornithology, wildlife, and Qatar's natural heritage.

By featuring the Caspian Tern, the State of Qatar highlighted the ecological importance of coastal and marine habitats that support migratory bird populations. The issue celebrated the diversity of avian life in the Gulf region and encouraged appreciation of wildlife conservation and the protection of habitats essential to migratory species.
