Brief introduction: The MacQueen's Bustard (Chlamydotis macqueenii (Gray, 1832)) is a large bird that breeds in southwest Asia in deserts and similarly arid sandy areas. It’s classification was recently split into a separate species from the Houbara Bustard of the Canary Islands and Africa. One difference is that the MacQueen's Bustard has a tendancy to wander compared with the Houbara.
