List of Otidiformes by population

From Wikipedia, the free encyclopedia

This is a list of Otidiformes species by global population. While numbers are estimates, they have been made by the experts in their fields. For more information on how these estimates were ascertained, see Wikipedia's articles on population biology and population ecology. This list is not comprehensive, as not all species have had their global populations estimated.

Species by global population

[edit]
Common name Binomial name Population Status Trend Notes Image
Great Indian bustard Ardeotis nigriceps 300[1] CR[1] Decrease[1] Maximum estimate. Equal to 250 mature individuals.[1]
Bengal florican Houbaropsis bengalensis 350-1,500[2] CR[2] Decrease[2] Equal to 250-999 mature individuals.[2]
Lesser florican Sypheotides indicus 730[3] CR[3] Decrease[3] Estimate for mature individuals only. Wider estimate is 356–1,228 mature individuals.[3]
Blue bustard Eupodotis caerulescens 12,000-15,000[4] NT[4] Decrease[4] Equal to 8,000-10,000 mature individuals.[4]
African houbara Chlamydotis undulata 20,000-49,999[5] VU[5] Decrease[5] Equal to 13,000-33,000 mature individuals.[5]
Great bustard Otis tarda 44,000-57,000[6] VU[6] Decrease[6]
Asian houbara Chlamydotis macqueenii 50,000-99,999[7] VU[7] Decrease[7] Equal to 33,000-67,000 mature individuals. Global population estimates are difficult to establish for this species.[7]
Australian bustard Ardeotis australis 100,000[8] LC[8] Decrease[8] Maximum estimate. Roughly equal to 6,700-67,000 mature individuals.[8]
Little bustard Tetrax tetrax 100,000-499,999[9] NT[9] Decrease[9] European subpopulation estimated at 122,000-240,000 mature individuals.[9]
Ludwig's bustard Neotis ludwigii 100,000-499,999[10] EN[10] Decrease[10] Estimate may be too wide. Further work to refine it is underway in Namibia.[10]
