What does the Ancient Greek root used for the genus *Numenius* refer to?

Answer

The crescent-shaped curve of the bill, like a new moon

The genus name *Numenius* is derived from the Ancient Greek term *noumenios*. This name is directly linked to the bird’s defining physical characteristic: its long, down-curved bill. The term is interpreted as relating to *neos* (new) and *mene* (moon), serving as a clear visual metaphor for the bill's shape resembling a waxing or waning crescent moon. This naming convention immediately groups the Whimbrel with other curlews based on this shared, distinctive bill morphology.
