Pheasant-tailed jacana

Hydrophasianus chirurgus


Common name:

Taxonomy:
Order Charadriiformes
Family Jacanidae

Range:
The pheasant-tailed jacana is found in southern and south-eastern Asia, including portions of Pakistan, India, Nepal, Sri Lanka, Myanmar, China, Java, and the Philippines.

Size:
These birds are 28-31 cm long, but the during the breeding season the long tails lengthen their total size to 45-50 cm. They weigh 120-150 g.

Habitat:
The pheasant-tailed jacana inhabits marshes, ponds, and lakes with patches of floating vegetation.

Diet:
They pick insects and other invertebrates from the floating vegetation or the water's surface.

Breeding:
Pheasant-tailed jacanas are polyandrous, with females having up to 4 mates at one time. They breed in March-September, with each male building a nest made of floating vegetation. The female lays 3-4 olive to dark-green eggs in each nest and each male is responsible for incubating and rearing the young. The male incubates the eggs for 24-26 days and the chicks are able to walk, swim and forage within hours of hatching. The male protects and broods the chicks for 6-7 weeks before they become fully independent.

Conservation:
IUCN status - LC (Least concern)
This species has a very large breeding range and a global population of 100.000 individuals. The population is suspected to be in decline owing to ongoing habitat destruction and degradation, but the pheasant-tailed jacana is not considered threatened at present.
