The curlews /ËkÉËrljuËz/, genus Numenius, are a group of eight species of birds, characterised by long, slender, downcurved bills and mottled brown plumage. The English name is imitative of the Eurasian curlew's call, but may have been influenced by the Old French corliu, messenger, from courir , to run.
