Greater painted-snipe
A polyandrous wader with reversed sexual dimorphism.
The greater painted-snipe (Rostratula benghalensis) is a medium-sized shorebird belonging to the small family Rostratulidae. It was first formally described by Carl Linnaeus in 1758, who placed it with the rails in the genus *Rallus* based on a drawing from Bengal. It is now classified in the genus *Rostratula*, which also includes the Australian painted-snipe, a species formerly considered a subspecies but elevated based on differences in morphology and calls. The greater painted-snipe is treated as monotypic, with no recognized subspecies. This species exhibits pronounced sexual dimorphism: females are larger, heavier, and more boldly patterned than males. The female has a black head with a buff stripe and a white eye-patch, a dark rufous neck, bronze-green upperparts finely barred with black, a white shoulder stripe, and a white underbody. The male is much paler and less uniform, with barring on the wing-coverts, while juveniles resemble the male but lack a darker chest band. Outside the breeding season, the bird is mostly silent, though females may produce a mellow hooting or booming sound. It is widely distributed across mainland Africa, Madagascar, the Seychelles, India, and Southeast Asia, though it is uncommon throughout its range. It inhabits wetlands such as swamps, marshes, and the edges of lakes and rivers, preferring muddy areas with nearby vegetation for cover. Typically solitary or in pairs, it is shy and skulking, retreating into cover when disturbed and flying with dangling legs like a rail. It feeds on insects, snails, earthworms, crustaceans, and plant seeds, using a scythe-like head and bill motion in shallow water, usually at dawn and dusk. Breeding is almost always polyandrous: females court males and may mate with two to four in a season, while males incubate the eggs and care for the young. The nest is a shallow scrape lined with plant material, concealed among grass or reeds near water. The clutch of four eggs is incubated by the male for about nineteen days. The chicks are precocial and nidifugous, buff-colored with black stripes. The species is listed as Least Concern by the IUCN due to its large range and slow population decline.

Lore & Background
The greater painted-snipe is a medium-sized shorebird, notable for its marked sexual dimorphism. Females are larger, heavier, and far more vividly colored than males. The female has a black head with a buff stripe and a white patch around the eye, a dark rufous neck, and upperparts that are a dark bronze-green with fine black barring. A distinctive white stripe curves around the shoulder mantle, while the underbody is white. Males are much paler and less uniform, with barring on the wing-coverts. Juveniles resemble males but lack the darker band across the chest. The species is not vocal outside the breeding season; females may produce a mellow hooting or booming sound. It is widely distributed across Africa, including Madagascar and the Seychelles, as well as southern Asia from India through Southeast Asia. It is absent from parts of Somalia, desert areas of Namibia, and portions of Botswana and South Africa. The bird inhabits a variety of wetlands, preferring muddy areas with cover such as vegetation. It is found on the edges of lakes and rivers, in marshes, swamps, ponds, and streams, typically near the fringes of reed beds. It is shy and retiring, skulking close to vegetation and flying like a rail with dangling legs when flushed.
Reader's Guide
The greater painted-snipe is significant for its unusual reproductive biology among shorebirds: females are polyandrous, often mating with two to four males in a season, while males solely incubate the eggs and care for the young. This role reversal is accompanied by reversed sexual dimorphism, with females larger and more brightly colored than males. The species is widely distributed across Africa and southern Asia but is generally uncommon within its range. It inhabits muddy wetlands with cover, feeding on insects, snails, earthworms, crustacea, and plant seeds using a scythe-like bill motion. Its conservation status is Least Concern due to its large range and slow population decline. The species is mostly silent outside the breeding season, though females may produce a mellow hooting or booming sound.
Did You Know?
- The female greater painted-snipe is larger and more brightly colored than the male, a reversal of typical bird dimorphism.
- Males incubate the eggs and care for the young, while females are polyandrous, mating with up to four males in a season.
- The Australian painted-snipe was once considered a subspecies but was promoted to full species status due to differences in morphology and calls.
Frequently Asked Questions
What is the Greater Painted-snipe?
It's a small wading bird (roughly 23–28 cm) in the family Rostratulidae, found across sub-Saharan Africa and the Indian subcontinent. It favors shallow wetlands such as swamps, marshy lake edges, and slow river banks.
Why is the female Greater Painted-snipe bigger and flashier than the male?
This species shows reversed sexual dimorphism: the female is both larger and more vividly colored than the male. That arrangement supports their polyandrous mating system, in which the showier female defends territory and mates while the male handles all parental duties.
Who incubates the eggs and raises the chicks?
The male sits on the clutch of about four eggs for roughly 19 days and then tends the hatchlings on his own. The female's involvement ends after she lays her eggs and moves on to seek another mate.
Where can I actually spot a Greater Painted-snipe?
Look along open, muddy or grassy margins of lakes, rivers, and seasonal swamps across Africa south of the Sahara and through the Indian subcontinent. They're most active in shallow, vegetated water rather than deep open water.
Is the Greater Painted-snipe endangered?
No—its IUCN listing is Least Concern, reflecting a broad range and tolerance of varied wetland types. The main ongoing threat is local loss of marsh and river-edge habitat to drainage or development, but the overall population remains stable.
