Lesser Jacana
Microparra capensisA tiny, elegant wader with extraordinarily long toes – a delicate dancer on Africa's floating vegetation.
The Lesser Jacana (Microparra capensis) is a small wader in the family Jacanidae, known for its extremely long toes and claws that enable it to walk on floating vegetation. It is the smallest of all jacanas, a delicate and graceful bird found in freshwater wetlands across sub-Saharan Africa, where it picks insects and seeds from the surface of lily pads and other floating plants.
Lesser Jacana Quick Facts
What Is the Lesser Jacana?
The Lesser Jacana (Microparra capensis) is a small wader belonging to the family Jacanidae, which includes the jacanas, also known as "lily-trotters". It was first described by the German naturalist Johann Friedrich Gmelin in 1789. The species name capensis refers to the Cape of Good Hope, where the species was first documented.
The Lesser Jacana is the smallest of all jacanas, a group of birds renowned for their extraordinarily long toes and claws, which allow them to walk on floating vegetation such as lily pads. Despite its tiny size, it is a fascinating and beautiful bird, with a delicate build and graceful movements.
The species is found across sub-Saharan Africa, from Senegal in the west to Ethiopia in the east, and southwards to South Africa. It is a resident bird in most of its range, though some populations may make local movements in response to rainfall and water availability.
How to Identify a Lesser Jacana
The Lesser Jacana is a distinctive and easily recognisable bird, especially when seen walking on floating vegetation. Here are its key identifying features:
- Size: A very small wader, measuring 15-18 cm (6-7 in) in length. It is the smallest of all jacanas.
- Plumage: The upperparts are brown, with a distinctive black stripe running through the eye. The underparts are white.
- Forehead: White forehead.
- Eye stripe: A bold black stripe extends from the bill through the eye to the side of the neck.
- Underwing: White, visible in flight.
- Tail: Short.
- Legs and toes: Extremely long toes and claws, adapted for walking on floating vegetation. The toes are greyish.
- Bill: Short and yellow-green with a darker tip.
- Breeding plumage: The male may show a deeper brown colouration on the upperparts during the breeding season.
- Non-breeding and juvenile: Similar to adults but may be paler and have less distinct markings.
Distinguishing from Similar Species
The Lesser Jacana can be confused with the African Jacana (Actophilornis africanus). The African Jacana is much larger (23-25 cm), has a more colourful plumage with a blue-grey body and chestnut wings, and is more brightly patterned. The Lesser Jacana is smaller, more delicate, and has a simpler brown-and-white colour scheme. The long toes are a shared characteristic of both species.
Behavior & Social Life
Lesser Jacanas are usually seen singly, in pairs, or in small groups. They are active and agile birds, often seen walking delicately on floating vegetation.
Locomotion
- Walking on vegetation: The Lesser Jacana's extraordinarily long toes and claws distribute its weight, allowing it to walk on floating plants such as lily pads, water lilies, and other aquatic vegetation.
- Flight: It has a short, rapid flight when disturbed, flying low over the water before dropping back into the vegetation.
Feeding Behavior
- Foraging: The Lesser Jacana picks insects, small invertebrates, and seeds from the surface of floating vegetation.
- Feeding technique: It walks delicately on lily pads, using its long toes to balance while picking prey from the water surface or vegetation.
Social Behaviour
- Pair bonding: Lesser Jacanas form pairs during the breeding season.
- Polyandry: Like other jacanas, the Lesser Jacana exhibits polyandry, where females mate with multiple males and the males take on the primary role of incubating eggs and caring for chicks.
Vocalization
Lesser Jacanas have a soft, high-pitched call, described as a "peep" or "weet" sound, often given in flight.
Habitat & Distribution
The Lesser Jacana is found in a variety of freshwater habitats with floating vegetation across sub-Saharan Africa.
Key habitat types include:
- Freshwater lakes and ponds – with abundant floating vegetation such as water lilies.
- Marshes and swamps – particularly those with floating plants and lily pads.
- Slow-moving rivers – with extensive floating vegetation.
- Seasonal floodplains – important feeding areas during the wet season.
Distribution: The Lesser Jacana has an extremely large range, with an Extent of Occurrence of approximately 26,000,000 km². It is found across much of sub-Saharan Africa, from Senegambia in the west to Ethiopia and Kenya in the east, and southwards to South Africa. The species is largely resident, though local movements may occur in response to rainfall.

Best Time to See Them
Lesser Jacanas are resident year-round in suitable habitat. The dry season (June to October) is generally best for wildlife viewing as birds congregate around remaining water sources. The breeding season typically occurs during the rainy season (November to May).
Diet & Feeding
The Lesser Jacana is primarily an insectivore, feeding on a variety of small invertebrates and seeds.
Food Sources
- Insects: Water beetles, flies, mosquitoes, and other aquatic insects.
- Small invertebrates: Spiders, small crustaceans, and worms.
- Seeds: Seeds of aquatic plants.
Feeding Behavior
The Lesser Jacana feeds by walking delicately on floating vegetation, picking insects and seeds from the water surface or from the leaves of aquatic plants. It uses its long toes to balance while foraging, often moving with surprising speed and agility.
Breeding & Life Cycle
The Lesser Jacana is polyandrous, with females mating with multiple males and males taking on the primary role of parenting.
Nesting
- Breeding season: Typically occurs during the rainy season, from November to May in East Africa.
- Nest site: A flimsy platform of aquatic vegetation, placed on floating plants such as lily pads.
- Nest construction: The male builds the nest, a small platform of aquatic vegetation.
- Clutch: 3 to 4 eggs.
- Incubation: 18 to 22 days, done primarily by the male.
Chicks
Chicks are precocial (born covered in down and able to move around soon after hatching). The male takes primary care of the chicks, feeding them and protecting them. Young fledge at 25 to 30 days old.
Conservation Status
The Lesser Jacana is assessed as Least Concern on the IUCN Red List.
Population: The global population is estimated at between 25,000 and 100,000 individuals. The population trend is stable.
Justification: This species has an extremely large range (26,000,000 km²) and hence does not approach the thresholds for Vulnerable. The population size is large, and the population trend is stable, so the species does not approach the thresholds for Vulnerable.
Threats: While the species is not currently threatened globally, it faces local threats including:
- Habitat loss: Drainage and degradation of wetlands.
- Pollution: Pesticides and other chemicals in water bodies.
- Human disturbance: Disturbance at breeding sites.
The Lesser Jacana is listed on CITES Appendix II and is protected by various international agreements, including the African-Eurasian Waterbird Agreement (AEWA).
