5 Euros Western Capercaillie

Part of Slovakia's ongoing nature conservation series, this issue highlights the western capercaillie (*Tetrao urogallus*), a ground-dwelling grouse whose Slovak populations have declined sharply due to forestry practices and habitat fragmentation. The National Bank of Slovakia has used the five-euro brass format consistently since 2021 to draw attention to endangered or ecologically threatened species, with each issue typically selling out through official channels before reaching secondary markets.
