This is a list of Ciconiiformes 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.
The IOC World Bird List (version 15.1) recognizes 20 species of Ciconiiformes. As of December 2025, IUCN/BirdLife International have assessed the populations of all members of this order. This list follows IUCN classifications for species names. Where IUCN classifications differ from other ornithological authorities, alternative names are noted.
Species by global population Common nameBinomial namePopulationStatusTrendNotesImage Storm's stork Ciconia stormi 300-1,750 Milky stork Mycteria cinerea 600-1,850 Best estimate of breeding population is 1,200-1,850 mature individuals. Oriental storkCiconia boyciana 1,000-2,499 Estimate for mature individuals. Greater adjutantLeptoptilos dubius 1,360-1,510 Total population is estimated to be 3,180-3,300 individuals. Lesser adjutantLeptoptilos javanicus 5,000-15,000 ? Saddle-billed storkEphippiorhynchus senegalensis5,200-15,000 Black-necked storkEphippiorhynchus asiaticus 10,000-30,000 Almost certainly an underestimate, but values provided are cautionary 'best guesses' for total population. African woollyneck (African woolly-necked stork)Ciconia microscelis20,000-53,000Total population is estimated to be 30,000-80,000 individuals. Painted stork Mycteria leucocephala 20,000-60,000 JabiruJabiru mycteria 20,000-85,000? Estimate for mature individuals. Another estimate has been made that places the population at fewer than 50,000 mature individuals. Black stork Ciconia nigra 21,400-42,100 ? Total population is estimated to be 32,110-63,100 individuals. Maguari storkCiconia maguari33,300-66,700Total population is estimated to be 50,000-100,000 individuals.Yellow-billed storkMycteria ibis50,000-100,000Total population is estimated to be 75,000-150,000 individuals.Asian woollyneck (Asian woolly-necked stork)Ciconia episcopus50,000-249,999Total population in South Asia alone is estimated to be 120,000-310,000 individuals.Wood storkMycteria americana144,000-756,000?Total population is estimated to be 216,600-1,133,900 individuals.Abdim's storkCiconia abdimii200,000-400,000Total population is estimated to be 300,000-600,000 individuals.Marabou storkLeptoptilos crumenifer200,000-500,000Values given are an estimate of total population.Asian openbillAnastomus oscitans300,000Current population size is likely larger than reported value. The estimate "dates from 2006 and does not account for the species' great range expansion since."African openbillAnastomus lamelligerus300,000-500,000Values given are for total population.White storkCiconia ciconia526,000-588,000European subpopulation estimated at 502,000-563,000 mature individuals.
