Last weekend we were monitoring Hostynske vrchy mountains, particularly local national natural reserves. Our goal was to monitor unprotected near-natural forests and occurence of endangered species like eurasian three-toed woodpecker (Picoides tridactylus) or white-backed woodpecker (Dendrocopos leucotos). Despite the fact that we didn't have an opportunity to observe these endangered treecreepers, we saw many other interesting things and natural beauties, see following photos.
