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.

Common name	Binomial name	Population	Status	Trend	Notes	Image
Storm's stork	Ciconia stormi	300-1,750[2]	EN[2]	[2]
Milky stork	Mycteria cinerea	600-1,850[3]	EN[3]	[3]	Best estimate of breeding population is 1,200-1,850 mature individuals.[3]
Oriental stork	Ciconia boyciana	1,000-2,499[4]	EN[4]	[4]	Estimate for mature individuals.[4]
Greater adjutant	Leptoptilos dubius	1,360-1,510[5]	NT[5]	[5]	Total population is estimated to be 3,180-3,300 individuals.[5]

Saddle-billed stork	Ephippiorhynchus senegalensis	5,200-15,000[7]	NT[7]	[7]
Black-necked stork	Ephippiorhynchus asiaticus	10,000-30,000[8]	LC[8]	[8]	Almost certainly an underestimate, but values provided are cautionary 'best guesses' for total population.[8]
African woollyneck (African woolly-necked stork)	Ciconia microscelis	20,000-53,000[9]	LC[9]	[9]	Total population is estimated to be 30,000-80,000 individuals.[9]
Painted stork	Mycteria leucocephala	20,000-60,000[10]	LC[10]	[10]
Jabiru	Jabiru mycteria	20,000-85,000[11]	LC[11]	?[11]	Estimate for mature individuals. Another estimate has been made that places the population at fewer than 50,000 mature individuals.[11]
Black stork	Ciconia nigra	21,400-42,100[12]	LC[12]	?[12]	Total population is estimated to be 32,110-63,100 individuals.[12]
Maguari stork	Ciconia maguari	33,300-66,700[13]	LC[13]	[13]	Total population is estimated to be 50,000-100,000 individuals.[13]
Yellow-billed stork	Mycteria ibis	50,000-100,000[14]	LC[14]	[14]	Total population is estimated to be 75,000-150,000 individuals.[14]
Asian woollyneck (Asian woolly-necked stork)	Ciconia episcopus	50,000-249,999[15]	NT[15]	[15]	Total population in South Asia alone is estimated to be 120,000-310,000 individuals.[15]
Wood stork	Mycteria americana	144,000-756,000[16]	LC[16]	?[16]	Total population is estimated to be 216,600-1,133,900 individuals.[16]
Abdim's stork	Ciconia abdimii	200,000-400,000[17]	LC[17]	[17]	Total population is estimated to be 300,000-600,000 individuals.[17]
Marabou stork	Leptoptilos crumenifer	200,000-500,000[18]	LC[18]	[18]	Values given are an estimate of total population.[18]
Asian openbill	Anastomus oscitans	300,000[19]	LC[19]	[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]
African openbill	Anastomus lamelligerus	300,000-500,000[20]	LC[20]	[20]	Values given are for total population.[20]
White stork	Ciconia ciconia	526,000-588,000[21]	LC[21]	[21]	European subpopulation estimated at 502,000-563,000 mature individuals.[21]
