Northern Shoveler (Anas clypeata)

This triangular postage due stamp (timbre taxe) celebrates Mauritania's aquatic environments and migratory waterfowl by depicting the Northern shoveler (Anas clypeata), locally labeled on the issue as canard souchet. The precise triangular engraving captures a pair of ducks standing near a seasonal water body, highlighting the male's distinctive spatulate bill, iridescent green head, and chestnut flanks against a soft greenish-grey gradient. This composition conveys a powerful message of biological conservation, wetland preservation, and the international significance of the Sahelian ecosystems that host diverse wintering bird populations. Issued for institutional use by the Islamic Republic of Mauritania, the stamp beautifully anchors the state's postal system within its local ornithological identity.
