The black-winged stilt (Himantopus himantopus) is a widely distributed wading bird in the avocetinidae family. It is found across much of the world in wetland habitats. Understanding where black-winged stilts live provides insights into their habitat requirements and conservation needs.

- Caribbean islands – Cuba, Jamaica, Dominican Republic, Puerto Rico
- South America – Colombia, Venezuela, Guyana, Suriname, French Guiana, Ecuador, Peru, Bolivia, Paraguay, Uruguay, Argentina, Chile
Some key wetlands include:
- San Francisco Bay in the United States
- Laguna Madre in Mexico
- Llanos wetlands in Venezuela
- Pantanal in Brazil
Habitat Preferences
Across their wide global range, black-winged stilts primarily inhabit open, shallow freshwater and brackish wetlands. Typical habitats include:
- Coastal saltmarshes and intertidal mudflats
- Coastal lagoons and estuaries
- Inland marshes, lakes and ponds
- Flooded agricultural fields and irrigation channels
- Rice paddies
- River deltas
- Edges of rivers and streams
Black-winged stilts favor wetlands with areas of exposed mudflats or shallow water up to around 30 cm deep. These provide ideal foraging habitat. They avoid overgrown, densely vegetated wetlands.
During the breeding season, black-winged stilts nest on open ground near water. Nest sites are often small islands or mounds within wetlands. They also use agricultural fields, salt pans, or grazed grasslands close to foraging habitat.
Geographic Variation
There are 19 recognized subspecies of the black-winged stilt:
Subspecies | Range |
---|---|
H. h. himantopus | Europe to central Asia |
H. h. meridionalis | Mediterranean region |
H. h. leucopterus | Russia |
H. h. weigoldicus | East Africa |
H. h. melanopterus | Southern Africa |
H. h. interior | Northwest and northeast Africa |
H. h. exterior | West Africa |
H. h. tectus | Southwest Asia to Pakistan |
H. h. asiaticus | South Asia |
H. h. sumatranus | Southeast Asia |
H. h. leucocephalus | Philippines |
H. h. ceramensis | Indonesia and southern New Guinea |
H. h. pallescens | New Zealand |
H. h. megalopterus | Australia |
H. h. cooki | Northwest Australia |
H. h. picatus | Central Pacific |
H. h. knudseni | Hawaii |
H. h. antofagastae | Coastal Chile and Peru |
H. h. lampronotus | Inland South America |
The variation between subspecies is largely clinal, with gradual geographic gradation in size and plumage tones. However, around 5-7 subspecies are commonly recognized. H. h. himantopus breeds in Europe and Asia and winters mainly in sub-Saharan Africa. H. h. meridionalis is resident around the Mediterranean. H. h. knudseni is the distinct resident Hawaiian subspecies. H. h. lampronotus breeds inland in South America.
Status and Conservation
The black-winged stilt has an extremely large global population estimated at 3.3-4.2 million individuals. The population appears to be stable, so the species is evaluated as Least Concern on the IUCN Red List. In some regions, populations have benefited from increased habitat in artificial and modified wetlands, such as salt pans, rice fields and wastewater treatment ponds.
However, black-winged stilts face threats from wetland habitat loss and degradation through drainage, pollution, invasive species and other human impacts. Conservation priorities include protecting key breeding and foraging wetlands through habitat management and restoration. Maintaining shallow, open areas of wetlands is vital. Reducing disturbance, managing water levels, and controlling invasive vegetation are other actions that can benefit black-winged stilt populations.
Conclusion
In summary, the black-winged stilt is a remarkably widespread species found across Africa, Eurasia, Australasia, and the Americas. It occurs in a diverse array of shallow freshwater and coastal wetlands. Conservation of these wetland habitats, which face many threats worldwide, is important for maintaining black-winged stilt populations into the future. Careful wetland management can provide quality breeding and foraging grounds for black-winged stilts.
