Summary
The Black-Crowned Crane is found in the Sahel and Sudan Savanna region of
Africa from the Atlantic coast to the upper Nile River basin. Two subspecies are
recognized. B. p. pavonina (the West African Crowned Crane), with an estimated
population of 11,500-17,500, occupies the western part of this range and is divided
into eight or more disjunct populations B. p. ceciliae (the Sudan Crowned
Crane), with an estimated population of 55,000-60,000, occurs in eastern Africa,
with the largest concentrations in southern Sudan. Historically, the species was
more numerous and more evenly distributed than at present. In the eastern part
of its range, its population is stable and relatively abundant. In the western
portions of the range, however, its numbers have declined and its range has been
reduced dramatically over the last two decades. The species is classified as Vulnerable
under the revised IUCN Red List Categories. B. p. pavonina is classified
Endangered, and B. p. ceciliae Vulnerable.
Black Crowned Cranes use both wet and dry open habitats, but prefer a mixture of shallow wetlands and grasslands (especially flooded lowlands in the sub-Sahelian savannahs). They can be considered both year-round residents and local migrants, flocking together during the dry (non-breeding) season and moving from large permanent wetlands to smaller temporary wetlands formed during the rainy season. Although they are non-migratory, daily and seasonal movements may in some areas range up to several dozen kilometers.
The principal threat facing the Black Crowned Crane is the loss, transformation, and degradation of its habitat. Behind this threat lies a combination of causal factors: extended drought in the Sahel and sub-Sahelian savannas, high human population pressures, intensive agricultural development and expansion, and extensive changes in hydrological systems as a result of dams, drainage, and irrigation projects. These factors are most pressing in West Africa, but also affect the species in the east. In some areas, these cranes are hunted for meat or captured and sold for trade. Ineffective enforcement of laws and the shortage of scientific research may also be considered long-term threats to the survival of the species.
The decline of the Black Crowned Crane in West Africa has begun to stimulate conservation efforts on behalf of the species. It is legally protected in most countries where it occurs, and many protected areas established in these countries harbor cranes. Several local surveys have recently been undertaken. In 1992, Nigeria hosted an International Conference on the Black Crowned Crane and Its Wetlands Habitat in West and Central Africa, and a Black Crowned Crane Coordinating Centre was established. No reintroduction program has been undertaken for the Black Crowned Crane, but the potential for reintroduction of the West African subspecies has been under discussion, and an experimental release has taken place in Nigeria.
Priority conservation needs for the species include: transfer of the species to CITES Appendix I; ratification of the Ramsar Convention by range countries and adoption of stronger national wetland protection policies and legislation; requirements for environmental impact assessments of large-scale development schemes affecting Black Crowned Crane habitat; increased support for existing protected areas and designation of new areas used by cranes; ecological research on wetlands and crane habitat requirements; a coordinated surveying and monitoring program for the species; collaborative projects involving local communities in the conservation and sustainable use of wetlands; establishment of a West African Crane Recovery Team; development of educational programs involving Black Crowned Cranes and wetlands; and expanded training opportunities for crane and wetland conservation specialists.

| West African Crowned Crane | B. p. pavonina |
| Sudan Crowned Crane | B. p. ceciliae |
The Grey and Black Crowned Cranes were combined within a single superspecies in the past, but are now considered separate species with two subspecies each. The subspecies of the Black Crowned Crane are most easily distinguished by differences in the coloration of their cheek patches. In B. p. pavonina, the lower half of the cheek patch is red; in B. p. ceciliae, the red extends into the upper half of the cheek patch (Johnsgard 1983, S. Haeffner pers. comm.).

Historic and Present Distribution
The Black-Crowned Crane is found in the Sahel and Sudan Savanna region of Africa from Senegal and Gambia on the Atlantic coast east to the upper Nile River basin in Sudan and Ethiopia (Walkinshaw 1964). Major wetlands—including the delta of the Senegal River, the inland delta of the Niger River in Mali, the delta of the Wazi River at Lake Chad in Camaroon, and the extensive Sudd wetlands in southern Sudan—are strongholds for the species (Eljack in press). B. p. pavonina occurs in the western part of this range, from Chad to Senegal, and is now thought to be divided into eight or more disjunct populations. B. p. ceciliae is found in eastern Africa, with the largest concentrations (an estimated 50,000 birds) in southern Sudan (Urban in press).
Historically, the Black Crowned Crane was more numerous than at present, and distributed more widely and evenly in the Sahel and sub-Sahelian savannas. The eastern portion of the population remains relatively abundant, although the population may be declining in eastern Sudan (Eljack in press). In western Africa, both the numbers and range of the Black Crowned Crane have declined dramatically since the onset of persistent drought in 1973 (Mustafa and Durbunde 1992). The drying up of wetlands, combined with increasing human population pressures, loss of habitat, and other threats, has fragmented the range of the subspecies and brought it to the verge of extinction in several countries. The population in Nigeria (where it was once abundant and is still the national bird) has been reduced to no more than 50-100 individuals (Urban in press, P. Hall pers. comm.).

Habitat and Ecology
Black Crowned Cranes use both wet and dry open habitats, but prefer freshwater marshes, wetter grasslands, and the edges of water bodies. The West African subspecies prefers a mixture of shallow wetlands and grasslands, especially flooded lowlands in the sub-Sahelian savannahs during the rainy season (generally June-September). They also forage and nest along river banks, in rice and wet crop fields, and even in abandoned fields and other dry lands, although always close to wetlands. In the eastern portion of its range, the Black Crowned Crane typically inhabits larger freshwater marshes, wet meadows and fields, and open areas of emergent vegetation along the margins of ponds, lakes, and rivers. These landscapes often include acacias and other trees, in which the cranes will roost.
Black Crowned Cranes can be considered both year-round residents and local migrants, flocking—often in large numbers—during the dry (non-breeding) season and moving from large permanent wetlands to smaller temporary wetlands during the rainy season. Their circular platform nests are built of grasses and sedges within or along the edges of densely vegetated wetlands. The average clutch size is about 2.5 eggs/nest. The incubation period is 28-31 days. The fledging period is 60-100 days (Walkinshaw 1973, Johnsgard 1983).
Soon after the chicks hatch, the cranes move into nearby open upland/grassland areas where they forage on insects and the fresh tips of plants. During the dry season, they forage in upland areas, frequently near herds of domestic livestock where invertebrates occur in greater abundance. If the rains fail, or if nesting habitat is deleteriously affected by drainage or overgrazing, crane pairs will remain in flocks throughout the year. Daily and seasonal movements between feeding and roosting areas are thought to be extensive (perhaps up to several dozen kilometers), but there has been little research on this aspect of their life history (Urban 1981).
Principal Threats
The principal threat facing the Black Crowned Crane is the loss, transformation, and degradation of habitat (Tréca in press). In the last two decades, wetlands and grasslands across the Sahel and Sudan Savanna regions, but especially in West Africa, have been devastated by natural forces and by the intensification of human land use. Drought and increased human pressures (especially overgrazing and destruction of tree cover) are widely considered to have contributed to the southward expansion of the Sahara Desert.1 Many seasonal and permanent wetlands (even those within protected areas) have been lost to desertification. At the same time, dramatic increases in human population have placed increased pressure on forest, range, and wetland resources (again, most severely in the west). In many areas, traditional forms of resource use have broken down, while intensified agricultural and industrial activities and large-scale development projects have been undertaken (Daddy and Ayeni in press). The environmental consequences, as they pertain to the Black Crowned Crane, are numerous and interrelated:
- Drought and population growth have forced people to migrate to relatively
moist, less populated regions (in, for example, Burkina Faso, Nigeria, and
Chad) containing prime crane habitat.
- Wetlands have deteriorated as a result of overgrazing and erosion in adjacent
lands, pollution, and heavy use of agricultural chemicals (Mustafa in press,
Scholte in press). In some areas, such as the Senegal delta, roost trees (Acacia
nilotica) have disappeared as a result of human demand for fuel and building
material.
- Wetlands have been drained to expand agricultural production (of, for example,
rice in Senegal) and to provide water for large irrigation projects. Drainage
and irrigation schemes have had a significant impact in Nigeria (in, for example,
the Hadejia floodplain and the Chad basin) and other parts of West Africa
(Fry 1987, P. Hall pers. comm.).2
- Dam construction has been a major thrust of national and international development
programs, especially in Cameroon, Nigeria, and Senegal. Impounded waters behind
the dams flood wetlands formerly used as nesting habitat by cranes. Downstream,
the reduced inflow and resultant changes in flooding cycles desiccate riparian
wetlands and allow floodplains to be converted to cropland.
- Intensification of agricultural systems has increased the level of pesticide use and the incidence of indiscriminate pesticide application. In particular, aerial spraying of pesticides has been heavily employed in the effort to control locusts, aphids, and other insect pests, as well as rodents and flocks of Black-faced Dioch (Quelea quelea) and Golden Sparrows (Passer luteus). This may directly impact cranes through the ingestion of poisoned food items, and indirectly through reduction of the food base (Mustafa and Durbunde 1992, Tréca in press).
In some areas, the species is hunted for meat or captured and sold. Hunting traditions vary widely within the species’ range. In some areas, the eating of cranes is taboo. In Sudan, the species is not normally hunted and is not considered edible (Eljack in press), but it has been hunted during times of war-induced famine. In Chad, Nigeria, and other countries, crane hunting still occurs when the opportunity arises, but cranes no longer occur in sufficient numbers to sustain the practice. Live-trapping probably poses a more significant threat. Black Crowned Cranes are trapped and sold at a considerable profit domestically and also to dealers for foreign export. During the 1970s, the trade in cranes was a problem in Nigeria in particular; the trade has since collapsed due to the decline in the crane population.
Beyond these direct threats, Black Crowned Cranes are also affected throughout their range by ineffective law enforcement, insufficient penalties for illegal activities, inadequate policies and legislation to protect key habitats, and a lack of educational programs emphasizing the importance of wetlands. Finally, there is a basic lack of detailed information on, and little ongoing research concerning, the Black Crowned Crane, its status, and its habitat.
1In 1994, abundant rains occurred through many parts of the Sahel, resulting in flooding to levels that had not occurred since the 1960s.
2B. Tréca (pers. comm.) notes that, in Senegal, Black Crowned Cranes often use harvested (dry) rice fields for feeding and resting, even when people are in close proximity. He notes that "the expansin of rice fields is not always a threat for Black Crowned Cranes, as long as some wetlands [are] left nearby."
Current Conservation Measures
Legal and Cultural Protection
Black Crowned Cranes are fully protected by law in most of the countries where they occur, although this protection is often ineffective. All the West African countries have enacted legislation protecting cranes. In some countries, such as Burkina Faso, cranes also benefit from the high regard in which they are held under local cultural traditions. There is little hunting pressure on the species in the eastern part of its range.
International Agreements and Cooperation
About half of the range countries of the Black Crowned Crane are parties to the Ramsar Convention (see Table 3.2).
In 1994 it was proposed that the species be transferred from CITES Appendix II to Appendix I. The proposal was withdrawn, but may be resubmitted.
In February 1992, an International Conference on the Black Crowned Crane and Its Wetlands Habitat in West and Central Africa was held in Kano, Nigeria. This meeting focused attention on the decline of the Black Crowned Crane in western Africa and served to launch the Black Crowned Crane Working Group. The 1993 African Crane and Wetlands Training Workshop in Maun, Botswana provided an opportunity to exchange information and to assess the status of the species across its range (Urban in press). The proceedings of the workshop include many of the papers from the 1992 conference as well (Beilfuss et al. in press).
Protected Areas
Black Crowned Cranes use many of the national parks, reserves, and other protected areas that have been established within their range. These include: Djoudj and Nikolo-Koba National Parks in Senegal; Diawling and Banc d’Arguin National Parks in Mauritania; Parc du W in Nigeria; Mare aux Hippopotames International Biosphere Reserves, Arli and Kabore Tambi National Parks, and Pama Game Reserve in Burkina Faso; Penjari National Park in Benin: Waza and Kalamaloue National Parks in Cameroon; Chad Basin National Park in Nigeria; the Ouadi Rime-Ouadi Achim Reserve in Chad; Bamingui-Bangoran and Manovo-Gounda-Saint Floris National Parks in Central African Republic; Randam and Dinder National Parks in Sudan; and Abijatta Shala, Gambella, and Mago National Parks in Ethiopia. However, protected areas in the region are often constrained by limited budgets and ineffective administration.
Habitat Protection and Management
Little habitat management has been undertaken specifically to protect or restore Black Crowned Crane habitat. However, many of the sustainable agriculture, agroforestry, reforestation, and wetland conservation projects undertaken in West Africa offer direct and indirect benefits for Black Crowned Cranes. No sustained habitat restoration studies are underway.
Surveys/Censuses/Monitoring
Urban (in press) provides country-level estimates of Black Crowned Crane populations based on information presented at the 1993 African Crane and Wetlands Training Workshop. The species has been reliably surveyed only in limited portions of its range. Local surveys were undertaken on the Inner Niger River Delta in the mid-1980s (Skinner 1988). Surveys have been conducted in Senegal since 1989 (Tréca and Ndiaye in press). Brouwer and Mullié (in press) report recent and historical observations in Niger. Portions of Nigeria and Cameroon have also been surveyed in recent years. Black-crowned Cranes have also been counted during the African Waterfowl Census conducted by the International Waterfowl and Wetlands Research Bureau (IWRB) (Taylor and Rose 1994, Davies in press). One of the main objectives of the proposed West Africa Subregion Management Plan Project (see below) is to undertake coordinated aerial and ground surveys of the species in the western portion of its range. Few surveys of the Sudan Crowned Crane have been undertaken. Eljack (in press) reports a probable total of 5000-7000 at Lake Kundi in western Sudan in 1993.
Research
Of the African cranes, the Black Crowned Crane is the most in need of detailed field studies. This reflects not only its rapid decline and threatened status in the western portion of its range, but also the limited extent of previous research (Urban 1987). Johnsgard (1983) summarized available information on the two subspecies (treating them together with the two Grey Crowned Crane subspecies). No range-wide surveys of the population and very few ecological studies of the species and its habitats have been carried out. Mustafa and Durbunde (1992) provide an overview of the species range and numbers in West Africa, while Urban (in press) summarizes the current status of the species throughout its range.
Non-governmental Organizations
A Black Crowned Crane Coordinating Centre was established in 1992 to carry out the work of the Black Crowned Crane Working Group. It is based in Kano, Nigeria and is currently headed by Hadi Mustafa of Nigeria. The Working Group on African Cranes (WGAC) also promotes research and conservation projects involving the Black Crowned Crane. The WGAC’s newsletter, The Crowned Crane, serves as a medium for information exchange.
Other non-governmental organizations, working at the national level, have also supported crane and wetland conservation projects. Naturama, a private conservation group in Burkina Faso, has worked to develop public interest in crane conservation. In Nigeria, Pro-natura, a community-oriented conservation organization, assists in crane protection programs (P. Hall pers. comm.). Also in Nigeria, the Hadejia-Nguru Wetlands Conservation Project was established in 1987 through a partnership of the Nigerian government and the Royal Society for the Protection of Birds with support from the Nigerian Conservation Foundation, BirdLife International, the Finnish International Development Agency, the Finnish Association for Nature Conservation and the British Council (Nigerian Conservation Foundation 1989, Hollis et al. 1993).
West Africa Subregion Management Plan Project
The International Crane Foundation and the Wildlife Conservation Research Centre in Accra, Ghana, have outlined a West Africa Subregion Management Plan Project for the Black Crowned Crane. The goal of the project is to develop a management plan for the West African Crowned Crane that will be endorsed by the governments of all the range countries in West Africa. The specific objectives of the project are to: (1) establish (in partnership with the Black Crowned Crane Coordinating Centre) a survey coordinating center, and contact cooperating individuals and institutions in the region; (2) undertake a region-wide survey and conservation status assessment; and (3) develop and gain support for a management plan for the subspecies. Further information on this project is available through ICF.
Education and Training In Nigeria, public education programs have begun to draw attention to the precarious state of the species within the country. The Hadejia-Nguru Wetlands Project has undertaken a comprehensive “Keep the Wetlands Wet” campaign to promote conservation education and awareness (R. Beilfuss pers. comm.). Several Nigerian conservationists have received training with ICF and the United Kingdom Jersey Wildlife Preservation Trust (Mustafa and Durbunde 1992). ICF has also developed long-term plans to provide further training, both in-country and at ICF’s training center.
Propagation and Reintroduction
The GCAR for cranes estimated that 448 Black Crowned Cranes were maintained in captivity worldwide as of 1993. Of these 31 were reported as B. p. ceciliae, and 122 as B. p. pavonina; the remainder had no subspecies designation. Regional studbooks for the species are maintained in North America and in the United Kingdom (Table 1.5), and regional captive management plans exist in North America and Europe. The species is considered moderately difficult to maintain in captivity and does not breed predictably (Mirande et al. in press a).
As yet, no ongoing reintroduction program has been undertaken for the Black Crowned Crane. The potential for reintroduction in West Africa has been under discussion, and one experimental release took place in Nigeria in 1992 in connection with the West African Crowned Crane Conference (Taylor and Rose 1994, Daddy and Ayeni in press, Garba in press). Discussions have also been held concerning the development of a captive propagation program in Borno State, Nigeria that can be linked with a release program at the Chingurme-Duguma sector of Chad Basin National Park, which probably holds Nigeria’s last remaining population. The GCAR has recommended that a release program be initiated only after existing habitat conditions have been thoroughly assessed and sound habitat management plans implemented.
Priority Conservation Measures
Legal and Cultural Protection- Adopt stronger wetland protection policies and legislation at the state
and national level throughout the species range. In particular, stronger laws
are needed to protect wetlands against over-exploitation, to prevent indiscriminate
use of pesticides and other harmful agricultural practices, and to discourage
encroachment upon and conversion of key crane habitats.
- Strengthen enforcement of existing laws prohibiting hunting and live-trapping
of cranes and safeguarding cranes within protected areas.
- Review and update existing laws and penalties to enhance the conservation status of the Black Crowned Crane at the national level, to prohibit trapping and shooting throughout its range, and to bring trade under control.
- Secure ratification and implementation of the Ramsar Convention in all the
range countries.
- Transfer the species from CITES Appendix II to Appendix I.
- Establish a West African Crowned Crane Recovery Team to oversee and guide
long-term conservation planning for the subspecies. The team should develop
a regional management plan that coordinates all recovery efforts within the
subspecies’ range.
- Provide increased support for the Black Crowned Crane Working Group. This support should allow the working group to play a more active role in informing policy makers on crane and wetland conservation policy, to strengthen contacts among the range countries, to coordinate research and conservation activities, to promote exchange of information, and to draw attention to specific problems at the local level.
- Strengthen existing protected areas that are important for Black Crowned
Cranes. Adequate funding, equipment, staffing, and training are needed to
allow these areas to function effectively.
- Assess the status of all areas where large concentrations of Black Crowned
Cranes are know to occur and identify core and buffer areas for potential
designation as protected areas.
- Designate new areas (especially key breeding areas) for protected status.
In areas where the Black Crowned Crane is scarce or has been extirpated, designate
for protection remaining habitat that is suitable for cranes. Such areas may
be designated, for example, as Wetlands of International Importance under
the Ramsar Convention, as national wetland reserves and crane sanctuaries,
or (in transfrontier areas with large wetland expanses) as international reserves.
Key areas for consideration include:
- the Inner Niger River Delta in Mali;
- the Senegal River basin in Senegal and Mauritania;
- the Hadejia-Nguru wetlands in northern Nigeria;
- the Lake Chad basin (especially the Chingurme-Duguma sector of Nigeria’s Chad Basin National Park, which is contiguous with Camaroon’s Waza National Park, allowing for possible designation of an international protected area); and
- the Sudd wetlands in southern Sudan.
- Undertake national-level inventories of wetlands, including all sites known
to, or potentially able to, support cranes.
- Develop integrated land use and conservation programs for critical wetlands
within the species range, including those of the Senegal River basin, the
Inner Niger River Delta, the Hadejia-Nguru wetlands, the Lake Chad basin (especially
those of Chad Basin National Park/Waza National Park region), and the Sudd
wetlands.
- Develop and implement plans for the restoration of degraded wetlands and
adjacent lands. Wetland restoration projects are most urgently required in
the western portion of the species’ range.
- Require environmental impact assessments for all large-scale development schemes affecting Black Crowned Crane habitat. Coordination of development and conservation projects should take place in accord with the provisions of the Ramsar Convention.
- Verify the status, distribution, size, and trends of the Black Crowned Crane
population through a coordinated surveying and monitoring program. This program
should focus initially on B. p. pavonina, and then be expanded to include
the species’ entire range. Among its other goals, the program should seek
to:
- conduct biannual surveys (aerial surveys during the nesting season and ground surveys during the flocking period) throughout the species’ range;
- delineate the distribution of populations and determine the degree of fragmentation in the range; and
- monitor trends in the population and its habitats by establishing standard observation sites (e.g., at Lake Chad) throughout the species’ range.
- Provide support for the West Africa Subregion Management Plan Project and
the Black Crowned Crane Coordinating Centre in Kano, Nigeria, to coordinate
surveying efforts and to disseminate results.
- Develop an updated species range map for the species.
In addition to research connected with other conservation measures (national-level inventories of wetlands, population and habitat surveys, refinement of husbandry techniques, etc.), research on the Black Crowned Crane should focus on:
- limiting factors in West Africa;
- basic ecological studies of wetlands and habitat requirements;
- the potential for reflooding to restore wetland habitat conditions in West
Africa;
- studies of various aspects of Black Crowned Crane biology, especially population
density, nesting success, productivity, feeding habits, and behavior;
- banding studies to understand local and seasonal movements and the demographics
of the populations;
- development of sustainable land use practices appropriate for the wetland-upland
complexes of the Sudan Savanna region; and
- studies of the status and environmental characteristics of specific protected areas and other critical habitats.
Community conservation projects are key to the long-term survival of the Black Crowned Crane and other wetland species in the species’ range. As specific projects are proposed, emphasis should be placed on involvement of various partners, including government agencies, local communities, non-governmental organizations, and schools and universities. The following activities should be given high priority:
- Develop and implement demonstration projects that involve communities in
the protection and management of local wetlands.
- Develop and implement integrated conservation programs for cranes that take
into account the basic needs of local people and that coordinate economic
development and conservation goals.
- Promote alternative employment opportunities for crane trappers and dealers.
- Work with community-based NGOs to develop monitoring, research, education, and habitat restoration programs for the species.
- Develop comprehensive conservation education and awareness programs involving
Black Crowned Cranes and their savannah/wetland habitats. These should be
aimed at the general public, focusing on communities that depend on wetlands.
- Develop education programs aimed at target groups—including crane trappers
and dealers, policy makers, students, agency personnel, and communities adjacent
to or within protected areas—within the range of the West African Crowned
Crane. In particular, extension programs employing a wide range of outreach
methods (e.g., lectures, posters, television, radio) are needed to disseminate
information on cranes, wetlands, and sustainable land use practices to farmers
and other land users.
- Expand opportunities for professional training in crane censusing and monitoring
techniques, ecological research, wetland management and restoration, and conservation
education.
- Provide support for publication and distribution of The Crowned Crane, the newsletter of the Working Group on African Cranes.
- Implement the recommendations outlined in the crane GCAR and CAMP (Mirande
et al. in press a). These are to:
- Determine the subspecies status of as many of the captive birds as possible. Guidelines for differentiating between the subspecies are available through the Denver Zoo in Colorado, U.S.A.
- Manage the captive population of B. p. pavonina at the Intensive-1 (B priority) level, with a target population of 200 birds. B. p. ceciliae is not currently recommended for captive management.
- Establish an international studbook for the species.
- Develop a regional captive management plan in Africa.
- After measures to ensure sound management of habitat have been effectively implemented, examine the potential for a release program aimed at reestablishing the species in portions of its range from which it has been extirpated.
- Undertake research to differentiate subspecies through genetic analysis and to refine captive propagation techniques.
- Develop in-country expertise in crane propagation and reintroduction techniques through increased training opportunities.
