Effects of habitat and land use on breeding season density of male Asian Houbara Chlamydotis macqueenii [PDF]

, 2016
Landscape-scale habitat and land-use influences on Asian Houbara Chlamydotis macqueenii (IUCN Vulnerable) remain unstudied, while estimating numbers of this cryptic, low-density, over-hunted species is challenging.
