1 Zlotnik Eurasian Spoonbill

The zlotnik is a pre-metric Ukrainian unit of weight historically equivalent to roughly 4.26 grams, revived here as a denomination name rather than a functional monetary unit — part of Ukraine's ongoing series celebrating native fauna under threat. The Eurasian Spoonbill breeds in scattered wetland colonies across Ukraine, including the Danube delta biosphere reserve, where habitat loss and drainage projects through the Soviet period reduced populations significantly before partial recovery under post-independence conservation law.
