The Slender-billed Curlew is nowadays considered extinct, with no birds officially observed in the last nearly 20 years or so worldwide (Corso, et al. 2014; Kirwan, et al.2015), while the Bald Ibis seems to be recovering with a rather small but increasing wild breeding population in Morocco (though the other wild very small one from Syria is gone forever) and some reintroduction projects elsewhere around Europe or “feral” populations (Spain, Austrian and Italian Alps, Turkey).
