The only known video footage and sound-recording of Slender-billed Curlew! The recordings were made at Merja Zerga, Morocco. The video is by Andy Butler, January 1994. The call was recorded by Adam Gretton, January 1999 with subsequent edits, to remove background noise, by J P Gautier and J P Richard at the laboratoire d'Ethologie de Rennes, as publised in Oiseax d'Afrique 1 by Claude Chappuis, and by Magnus Robb.
For comparison, footage and calls of Whimbrel and Eurasian Curlew follow. Does anyone have any footage of the orientalis or sushkini subspecies of Eurasian Curlew or the alboaxillaris subspecies of Whimbrel?

The Slender-billed Curlew call can also be downloaded from this website and makes the ultimate mobile phone ringtone! The more people who become familiar with this call, the higher the likelihood that they will be alert to hearing such a call in the field. It is the distinctive Slender-billed Curlew call described as Eurasian curlew-like immediately followed by 6-7 very short notes "ti-ti-ti..." becoming progressively higher in pitch and reminiscent of certain larger raptors.The Eurasian curlew-like part of the call is softer, sweeter, faster and higher in pitch, consisting of four identical cour-lee calls with 0.25 seconds pause in between, second syallable distinctly higher in pitch than first. The tittering part of the call is higher pitched than the distinctive 'bi, bi, bi, bi, bi, bi, bi' of the Whimbrel. It was given by a single Slender-billed Curlew flying into a feeding area with a small group of Eurasian Curlews (Gretton 1991). This call was not heard during the previous year and as this individual had been shot and wounded in early December 1989 it is possible that the call is atypical.'
