Which of these birds has a down-turned bill?

The curlews, genus Numenius, are a group of eight species of birds, characterised by long, slender, down-turned 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". It was first recorded in 1377 in Langland's Piers Plowman "Fissch to lyue in þe flode..Þe corlue by kynde of þe eyre". The genus name Numenius is from Ancient Greek noumenios, a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from neos, "new" and mene "moon", referring to the crescent-shaped bill In Europe "curlew" usually refers to one species, the Eurasian curlew Numenius arquata.

Curlews feed on mud or very soft ground, searching for worms and other invertebrates with their long bills.

Curlews enjoy a worldwide distribution. Most species show strong migratory habits and consequently one or more species can be encountered at different times of the year in Europe, Ireland, Britain, Iberia, Iceland, Africa, Southeast Asia, Siberia, North America, South America and Australasia.
