The Bird in your Backyard - Bronze Winged Jacana
By Dr Anand & Geeta Pereira

August 13, 2013


The Bronze winged Jacana pictures that you are about to view are commonly observed in water bodies, ponds, lakes, wet lands, marshy areas in and around Mangalore and almost in all similar habitats throughout India. We request you to take time to stop while you drive towards Padil, Bejai, Nantoor, Kavoor, Ullal, or Suratkal and observe these bronze colored beauties in their natural wetland habitats. This brief article is written to awaken the senses of the common citizens to the accelerated disappearance of marshy areas and wetlands in and around Mangalore in particular and the rest of the Country in general, leading to the disappearance of these winged beauties. Today, many of these habitats in and around cities are drained to allow for urbanization. These natural buffering areas continue to be under direct and indirect pressures from human settlement that may result in further loss or degradation.

As explained in most of our earlier articles on nature conservation, this particular article is written as an eye opener to maintain the natural balances disrupted by recent human activity. These wetlands help buffer the city from cyclones, floods and drought. Little do we realize that these wetland and marshy areas are our first line of defense during tropical storms? However, due to construction activity, many of these wetlands are disappearing at a spectacularly swift pace. By 2020, if nothing is done to stop this process, the country could lose more than 50 % of the coastal wetlands. Importantly, our beautiful city Mangalore with its pristine surroundings will become even more vulnerable to future impacts of climate change in the form of cyclones and floods.

The many pictures depicted in this article capture the Bronze winged Jacana's bird movement right from an adult to a juvenile. Whenever we have the opportunity to write an article and post pictures in Daijiworld, we take care to provide pictures of the subject in many different angles so that school children and nature lovers can identify the birds more accurately in the field. Kindly note, a small shift in angle will reveal altogether new details that are important for identification. We do hope you enjoy the pictures and take time to spot these wonders during your week end sojourns.

The Bronze winged Jacana are a group of waders with short tails. The legs and toes are long with enormous straight claws which enable the birds to run easily over the floating leaves of aquatic leaves. The bird has a wide distribution throughout India. The bird is sedentary and the female lays four black marked brown eggs in a floating nest. The males take responsibility for incubation. These birds can also be found in ponds very close to human habitation and when disturbed or threatened seek refuge in the undergrowth of weeds or try to hide by covering lotus leaves as depicted in a few of the pictures. Even though, scientific literature points out to the fact that these birds are highly territorial, our observations point out that that a group of six to seven birds share a common territory. We have observed a large population of these birds during summer times and they wonderfully co exist with humans.

Description: These are conspicuous and unmistakable birds. They are 28 to 29cm (~11") long, but the females are larger than the males. Adult birds have beautiful bronze colored wings, with a striking white eye stripe. The yellow bill extends up as a red coot-like head shield, and the legs and very long toes are grey. Young birds have brown upperparts. Their under parts are white, with a buff fore neck.

Diet: The Bronze-winged Jacana's feeds on insects and other invertebrates (= animals without internal skeleton, such as larvae, earthworms, millipedes, snails, spiders) picked from the floating vegetation or the water's surface.

Mating: Bronze Winged Jacanas have a territorial, sex-role reversed system. They are polyandrous, and the females are larger and more brightly colored than their male counterparts. The females compete with each other for harems of males to incubate their clutches of eggs. Each female’s territory encompasses one to four males and their individual territories.

Conclusion: The relation between wetlands and birds is shaped by many factors like availability of food and shelter.  We have observed many species of birds in and around Mangalore, both resident and migratory, but over the past few years (5 years) bird numbers seem to be declining and the single most threat to birds is Habitat loss. Loss of such wetland ecosystems has huge impact on birds because many aquatic birds depend on wetlands almost totally for breeding, nesting, feeding, or shelter during their breeding cycles. Another important point that we would like to make is that there is very little information regarding the Bronze winged Jacanas behavior on the World Wide Web. It is time, for students to carry out a small project on this beautiful bird and publish it on the net.

Dear Dr Anand Sir and Geetha Madam,
Thank u for educative article Bronze winged Jacana,s , I really grateful for ecological alarming massage for those least concern about nature, ecology and environment .You have nicely narrated the and forecasted the massage that, in future Mangalore is under threat because of recent urbanization and globalization. Disappearance of Bronze winged Jacana,s is ecological imbalance / treat indicator for Mangalore and for all urbanization areas too .
This is wonderful massage for, basic Mangalurians , future thinkers, administrators, policy makers, Mangalore Corporatist and Common citizens of Mangalore go back to their dreams and think and realize sanctity , prosperity of Mangalore 15-20 years back and what is now?
After reading your article I have wondered being Mangalore is of costal, water rich wet land and marshy and slowly vanishing its own beauty and sanctity because of modern invaders.
Your photos are mind blowing and crystal clear clarity in colorific description of bird morphology and habitat. Your zoological and physiological massage, Bronze winged Jacana,s polyandrous and male have role incubation of eggs is very much interesting and excellent.
Your article surely educate the common man regarding the conservation of the Bronze winged Jacana,s by way of not destroying the marshy and wet land that may help like buffer for floods and draughts .
Now also Mangalurians, administrators did not wake up in this regard, time and nature will teach the lesson like Uttarakand fllods etc. for humanity
Thank for devote your precious time for thinking about goodness of Mangalore, We request to keep updating future threats for ecology and environments.
Regards
Sowmya and Prabhu H V

The bronze winged Jacana is a real beauty(beau). The angle you have clicked the pictures are awesome. One can just keep watching them on and on. Truly agree with you, if one does not maintain the coastal wet lands,our place will be more and more vulnerable to the natural calamities.Superb work. Appreciate your dedication and patience. You both are a true inspiration to the younger generation and also people at large.

Conservation is too far to achieve as we are on our way to destruction. Its very late now as it is irrepairable, lets wait and see if money power will work with nature.
