Template:Birds by population sidebar 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.[1] 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

Milky stork Mycteria cinerea 600-1,850[3] Template:IUCN-EN[3] Decrease[3] Best estimate of breeding population is 1,200-1,850 mature individuals.[3] 175px
Oriental stork Ciconia boyciana 1,000-2,499[4] Template:IUCN-EN[4] Decrease[4] Estimate for mature individuals.[4] 175px
Greater adjutant Leptoptilos dubius 1,360-1,510[5] Template:IUCN-NT[5] Increase[5] Total population is estimated to be 3,180-3,300 individuals.[5] 175px

Saddle-billed stork Ephippiorhynchus senegalensis 5,200-15,000[7] Template:IUCN-NT[7] Decrease[7] 175px
Black-necked stork Ephippiorhynchus asiaticus 10,000-30,000[8] Template:IUCN-LC[8] Decrease[8] Almost certainly an underestimate, but values provided are cautionary 'best guesses' for total population.[8] 175px
African woollyneck

(African woolly-necked stork)

Ciconia microscelis 20,000-53,000[9] Template:IUCN-LC[9] Increase[9] Total population is estimated to be 30,000-80,000 individuals.[9] 175px
Painted stork Mycteria leucocephala 20,000-60,000[10] Template:IUCN-LC[10] Increase[10] 175px
Jabiru Jabiru mycteria 20,000-85,000[11] Template:IUCN-LC[11] ?[11] Estimate for mature individuals. Another estimate has been made that places the population at fewer than 50,000 mature individuals.[11] 175px
Black stork Ciconia nigra 21,400-42,100[12] Template:IUCN-LC[12] ?[12] Total population is estimated to be 32,110-63,100 individuals.[12] 175px
Maguari stork Ciconia maguari 33,300-66,700[13] Template:IUCN-LC[13] Steady[13] Total population is estimated to be 50,000-100,000 individuals.[13] 175px

Asian woollyneck

(Asian woolly-necked stork)

Ciconia episcopus 50,000-249,999[15] Template:IUCN-NT[15] Decrease[15] Total population in South Asia alone is estimated to be 120,000-310,000 individuals.[15] 175px
Wood stork Mycteria americana 144,000-756,000[16] Template:IUCN-LC[16] ?[16] Total population is estimated to be 216,600-1,133,900 individuals.[16] 175px
Abdim's stork Ciconia abdimii 200,000-400,000[17] Template:IUCN-LC[17] Decrease[17] Total population is estimated to be 300,000-600,000 individuals.[17] 175px
Marabou stork Leptoptilos crumenifer 200,000-500,000[18] Template:IUCN-LC[18] Decrease[18] Values given are an estimate of total population.[18] 175px
Asian openbill Anastomus oscitans 300,000[19] Template:IUCN-LC[19] Increase[19] Current population size is likely larger than reported value. The estimate "dates from 2006 and does not account for the species' great range expansion since."[19] 175px
African openbill Anastomus lamelligerus 300,000-500,000[20] Template:IUCN-LC[20] Steady[20] Values given are for total population.[20] 175px
