Origin, geographical range and distribution
The bronze-winged jacana species are distributed in India, Pakistan, Bangladesh, Myanmar, China, Thailand, Cambodia, Laos, Vietnam, Malaysia, Nepal and Indonesia. The Important Bird and Biodiversity Area (IBA) of these jacana species in Vietnam is U Minh Thuong.In India, the bronze-winged jacana species are distributed in Gujarat, Rajasthan, Haryana, Uttarakhand, Uttar Pradesh, Bihar, Madhya Pradesh, Chhattisgarh, Odisha, Jharkhand, West Bengal, Assam, Meghalaya, Nagaland, Manipur, Tripura, Telangana, Maharashtra, Andhra Pradesh, Goa, Karnataka, Tamil Nadu and Kerala.
Ecosystem and habitat
These bronze-winged jacana species do not normally occur in forests. These species occur in altitudes from 0 to 100 meters. The artificial ecosystems of these jacana species include seasonally flooded agricultural land and aquatic ponds and water reservoirs.The natural ecosystems of these bronze-winged jacana species include wetlands with floating and emergent vegetation, tropical and subtropical flooded grasslands, peatlands, marshes, bogs, swamps, freshwater lakes and ponds.
Diet and feeding behavior
The diet of these bronze-winged jacana species is mostly insects. Insects, small molluscs, worms, larvae, beetles, seed and plant material are their primary food.Reproduction and breeding habits
The breeding season of these bronze-winged jacana species is mainly in monsoon season in South India. The breeding season is during June in Indonesia. These species are polyandrous, the female partnering with more than one male in a breeding season.Female bronze-winged jacana form harem territories, which include the territories of 1-4 males. The females defend their territory aggressively from other females. The males also defend their territory from other males.
Before laying eggs the female bronze-winged jacana may spend more time with a receiver male. After laying eggs, the receiver male takes over the responsibility of brooding and raising chicks. Meanwhile the female moves to the territory of another male and provides him with another clutch of eggs.
Migration and movement patterns
The bronze-winged jacana species are non-migrant resident birds. Post breeding, the bronze-winged jacana juveniles may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.Bronze-winged jacana - Overview

Conservation and survival
The global population size of the bronze-winged jacana (Metopidius indicus) has not been quantified. The overall population trend of these species is considered to be stable. Throughout its range it is reported to be common to rare. The generation length is 4.8 years. Its distribution size is about 11,600,000 sq.km.The bronze-winged jacana (Metopidius indicus) does not approach the thresholds for being Vulnerable, either under the range size criterion or under the population trend criterion, or under the population size criterion. The ongoing draining of wetlands, habitat destruction and fragmentation and hunting are the main threats that may endanger the survival of these jacana species.
IUCN and CITES status
The IUCN (International Union for Conservation of Nature) has categorized and evaluated the jacana species and has listed it as of "Least Concern". The CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Not Evaluated’ for the bronze-winged jacana (Metopidius indicus).1.Photo source: https://commons.wikimedia.org/wiki/File:Bronze-winged_Jacana_-_Kang_Kra_Chan_-_Thailand_S4E5460_(14256635032).jpg (cropped)
