The Bronze-winged Jacana (Metopidius indicus) is an enthralling bird species originating in South Asia that draws the attention of birdwatchers and wildlife aficionados alike. This feathered beauty captivates with its stunning looks and peculiar habits. In this article, we'll explore the classification and physical traits of the Bronze-winged Jacana, their preferred habitat and diet, as well as their reproduction and nesting habits, and lastly, their presence in Nepal.
Classification and Physical Traits
As a member of the Jacanidae family, the Bronze-winged Jacana (Metopidius indicus) has a distinctive place among jacanas. This medium-sized wading bird is about 30 cm long and weighs approximately 200 grams. It boasts a beautiful chestnut brown plumage accompanied by bronze-hued wings, making it an undeniably eye-catching specimen. Its lengthy legs and extended toes allow for easy traversal of floating wetland vegetation - a crucial skill for its survival.
A standout feature of the Bronze-winged Jacana is its contrasting black neck with white streaks that highlight its brilliant yellow eyes. Males and females share similar physical traits, with slight differences visible only during the breeding season.
Living Spaces and Diet
These elusive birds have a penchant for shallow freshwater wetlands teeming with dense vegetation, such as marshes, ponds, lakes, and swamps. Their habitat spans across South Asia, including regions like India, Bangladesh, Sri Lanka, Myanmar, Thailand, Cambodia, Laos, Vietnam, Philippines, Indonesia, and Malaysia.
Bronze-winged Jacanas mainly feast on insects discovered among floating vegetation or near water surfaces. Although they have an inclination for insects like beetles and bugs—their staple diet—they are omnivores who also consume plant material, such as seeds and aquatic vegetation.
Reproduction and Nesting
Breeding usually takes place during the monsoon season when plentiful waters produce ideal nesting conditions. The Bronze-winged Jacana showcases an unusual mating system called polyandry. Contrasting with typical bird mating behaviors, the female mates with multiple males who then take responsibility for incubating eggs and caring for chicks post-hatching. Female Jacanas are known to be territorial, ardently defending their nest sites against other females to secure successful reproduction.
Nests are commonly built on floating vegetation or slightly elevated platforms near water edges. Clutches typically comprise four eggs, each showcasing a pale olive hue decorated with reddish-brown speckles. After 22 days of incubation, chicks hatch equipped with remarkably long legs and feet, allowing them to expertly navigate their wetland habitat from a young age.
Whereabouts in Nepal
Nepal hosts various beautiful birds, including the Bronze-winged Jacana. They inhabit wetlands in the Terai region, primarily in locations like Koshi Tappu Wildlife Reserve and Ghodaghodi Lake area. These destinations provide suitable habitats for these birds to flourish in their preferred environment.
In conclusion, the Bronze-winged Jacana (Metopidius indicus) distinguishes itself among different bird species due to its captivating appearance and fascinating behavior patterns. From their eye-catching physical traits to their unique feeding habits and breeding systems, this less-known bird reflects the abundant biodiversity nestled within our planet's wetlands.
