This attractive USSR commemorative bird set, issued in 1982, celebrates the XVIII International Ornithological Congress held in Moscow. The stamps feature finely illustrated bird species rendered in a naturalistic scientific style, reflecting the strong Soviet tradition of wildlife and ornithological art. Depicted species include Eurynorhynchus pygmeus (Spoon-billed Sandpiper), Haliaeetus pelagicus (Steller’s Sea Eagle), and Eulabeia indica (Bar-headed Goose), each identified by Latin nomenclature on the design. Issued with clear thematic relevance and international scientific significance, this set is highly appealing to bird, wildlife, and thematic collectors, as well as specialists in Cold War-era Soviet commemoratives.
