Range Description

Neotis nuba has a disjunct range across the Sahelian and, marginally, Saharan zones of Africa. The western subspecies N. n. agaze has populations in Mauritania, Mali, Burkina Faso, Niger and western Chad, and the eastern subspecies N. n. nuba has a single population in eastern Chad and Sudan (Johnsgard 1991). N. n. agaze was formerly common in Mali and Mauritania and probably remains common only in Chad and Niger, while N. n. nuba is described as rare and little known in Sudan (Urban et al. 1986, Nikolaus 1987). Vehicle-based transect surveys for raptors in the Sahel zone of Mali and Niger in 2004 failed to record any bustard species, despite N. nuba being frequently recorded along the same transects in 1971 and 1973 (Thiollay 2006). Bustards can be inconspicuous, which, coupled with the focus of these surveys on raptors, means that some birds were probably missed, and local hunters reported that bustard species were still extant in the surveyed areas; however, the difference between the survey results from the early 1970s and 2004 most likely indicates dramatic declines in this species (Thiollay 2006). Several hundred kilometres of vehicle-based transects have been conducted recently in Mauritania in search of N. nuba, without any success by January 2012 (K. DuRose in litt. 2012).
