The pheasant-tailed jacana (Hydrophasianus chirurgus) is a large wader from Southeast Asia. They inhabit wetlands and large lakes where they spend their time walking across floating aquatic vegetation, gleaning insects from plants or the water’s surface. This jacana species is distinct from others in its family due to its propensity for long-distance travel and variations in its breeding plumage.

5 Amazing Pheasant-Tailed Jacana Facts

• The pheasant-tailed jacana is the only species in its family that migrates long distances.
• They are strong fliers with rapid wingbeats, which is unusual for jacanas.
• This bird displays distinct plumage during the breeding season, including a long tail.
• People have spotted these birds as far south as Australia.
• Populations in Eastern China face habitat destruction of their wetland homes.

Where to Find the Pheasant-Tailed Jacana

The pheasant-tailed jacana lives in Southeast Asia in 22 countries, including India, China, Indonesia, Japan, Singapore, and the Philippines. Most populations are year-round residents. Those living in more northern regions, like the Himalayas, migrate south to lower elevations during winter. They inhabit significant freshwater wetlands, lakes, and ponds, especially those with abundant aquatic vegetation like water lilies.

Nests

Males make loosely constructed platforms on floating aquatic vegetation. Occasionally, they add plants around the eggs as nesting material to help conceal them. The male will move his eggs to a drier location if the nest becomes flooded.

Classification and Scientific Name

The pheasant-tailed jacana (Hydrophasianus chirurgus) is from the Charadriiformes order, which contains around 391 bird species found across diverse habitats worldwide. The Jacanidae family encompasses the jacanas, a group of tropical waders. This species is in the monotypic Hydrophasianus genus. The genus means “water pheasant.”

Size, Appearance, & Behavior

The pheasant-tailed jacana is a large wader and the longest species in the jacana family. They measure 15 to 23 inches long and weigh four to nine ounces, with a tail accounting for roughly 10 inches of their total length. This species showcases different plumage during the breeding season. Its breeding plumage consists of long tail feathers, dark brown bodies, white faces, and a black crown with white stripes running down the sides of its neck. Its wings are white with black tips. Their tails are much shorter outside of the breeding season. Its upper parts are greenish-brown, and the sides of its neck are a dull golden-yellow. There is also a dark brown band that wraps around its neck.

Its calls are loud mewing or nasal sounds, which they make within their wintering flocks. This species is relatively social, often found in groups of up to 100 individuals. Unlike other jacanas, the pheasant-tailed jacana is a strong flier with rapid wingbeats and can travel long distances.

Migration Pattern and Timing

Pheasant-tailed jacanas are the only jacanas that travel long distances. Most populations are sedentary, but those found in northern regions, like the Himalayas, will migrate to Southeast Asia and India. This jacana has been seen as far south as Australia. They leave in November and return mid to late April.

Diet

Pheasant-tailed jacanas are carnivores that primarily eat insects.

What Does the Pheasant-Tailed Jacana Eat?

Aquatic insects are their main prey, but they will also consume small fish, snails, worms, crabs, mollusks, and seeds. They forage for food by walking across floating vegetation and gleaning insects off aquatic plants, occasionally picking seeds from water lilies.

Predators, Threats, and Conservation Status

The IUCN lists the pheasant-tailed jacana as LC or “least concern.” Due to its extensive range and large population, this species does not meet the thresholds for “threatened” status. These jacanas are not globally threatened, but some populations in Eastern China face habitat destruction and degradation of their wetland homes. 

What Eats the Pheasant-Tailed Jacana?

Their most significant predators include snakes, turtles, large fish, various mammals, crocodiles, and birds of prey. This species is highly susceptible to nest predation, and fathers are very protective of their young. To defend themselves and their young, adults make loud alarm calls, perform threat displays, and use their bony wing spurs to attack intruders.

Reproduction, Young, and Molting

Breeding season occurs during summer in the northern regions of its range, but coincides with the monsoon season across India and Southeast Asia. Most jacanas participate in a polyandrous mating system, where the females lay egg clutches with multiple partners and the males bear all responsibility for raising the young. Males will destroy egg clutches when they are uncertain of their paternity. Females typically lay four eggs, and the males incubate them for approximately 24 to 29 days; the young stay with their father for up to two months. Pheasant-tailed jacanas become sexually mature around two years old and have an average lifespan of 4.8 years.

Population

The global pheasant-tailed jacana population is estimated to be between 20,000 and 33,300 mature individuals. Although no extreme fluctuations or fragmentation are occurring, the population is declining due to habitat destruction.
