Sixty-four birds were seen in four distinct areas. Adult males were seen displaying at three of these areas, indicating that they are probably traditional lek sites. No adult males were observed in the fourth area and its status as a lek site is uncertain. Two further sites were visited but no birds were seen. Two 1st-year males were seen with their mothers, demonstrating successful breeding in 1998. We argue that the small number of birds, a population sex ratio of 1 : 3.3 in favour of females, evidence for a range contraction, and probable isolation from other great bustard populations mean that this population is now extremely endangered and will decline to extinction unless conservation measures are implemented immediatelyThe survey was co-financed by the British Ecological Society (SEPG No. 1577 to S.J.L.) and The International Foundation for Conservation and Development of Wildlife (IFCDW), Inezgane, Morocco, who generously provided a car and driver. Particular thanks are given to Dr Sami Jamil Jadallah for his encouragement and support, and to His Royal Highness Prince Sultan bin Abdul Aziz al Saud of the Kingdom of Saudi Arabia, patron and sponsor of IFCDW. S.J.L. was supported by a Marie Curie Research Training Grant awarded under the Training and Mobility of Researchers Programme by the European Commission Directorate General XIIPeer reviewedCambridge University Press201320132000info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/77399reponame:DIGITAL.CSIC.
