Spotting a bar-headed goose, a Eurasian spoonbill or a painted stork in the wetlands of Tamil Nadu is becoming increasingly difficult because of the rampant illegal hunting of waterbirds. The hunting, at scales not mapped before, is triggered by demand from the market for wild meat and not subsistence hunting by a few, a new study by researchers at the Nature Conservation Foundation in Mysuru has found.
The researchers studied 27 wetlands in Tamil Nadu’s Kancheepuram district and interviewed 272 hunters over six months. Recording around 53 waterbird species across the wetlands during eight months of fieldwork in 2013 and 2014, they found that 47 species were being hunted, especially large and medium-sized birds. They also held that the hunting had contributed to a decline in the diversity of species found in the region, especially medium-sized insectivorous birds.
The study, based on a survey of hunters, concluded that the illegal hunting of waterbirds was market-driven and had grown in scale in the last 10 years. This contradicts previous findings by researchers that hunting is usually taken up by certain communities on a small scale purely for subsistence. Around 73.5% of the respondents reported monetary gain as the primary motive for hunting, sport and subsistence being the other reasons.
“The conclusions were in contrast to what we expected,” said Ramesh Ramachandran, an MSc student in wildlife biology and conservation at the National Centre for Biological Sciences in Bengaluru, who undertook this study as part of his dissertation. “We thought this was a traditional practice that had been there for hundreds of years. But it is a total commercialised mafia.”
The hunting of wild animals driven by a demand for wild meat, which is seen as exotic by some in the richer strata of society, is documented in some other parts of the country, particularly the tribal belts of Central India and the North East, but this research shows the same trend prevailing in Tamil Nadu as well.
Policeman to conservationist
Before taking up wildlife conservation studies, Ramachandran was a policeman in Karnataka and a member of a special cell tracking wildlife crime. “Because of his background, he brings an interesting viewpoint to conservation,” said KS Gopi Sundar, his mentor and scientist at the Cranes and Wetlands Programme of the Nature Conservation Foundation.
Ramachandran narrowed down his area of study to Kancheepuram, which has a large number of lakes and waterbodies, including two protected bird sanctuaries – Vedanthangal and Karikili.
His police training helped him track down communities that hunted wild birds and traded in their meat. He said he worked at winning their trust before presenting them with the questionnaire for the study. With a team of wildlife enthusiasts and informants, he visited them several times to get them to participate in the study.
At the end of their research, the team found that 92% of the hunting was done using locally crafted single-barrel muzzle-loading guns. A hunter on average went out four or five times a month and each trip yielded around 21 birds, which earned him an average monthly income of around Rs 13,000. The most commonly traded meat was that of the pond heron.
Around 71% of the respondents reported an increase in the demand for waterbird meat for consumption over the past decade. And the study found two distinct markets existing for the wild meat. It was sold at a fixed time slot, between 6 pm and 8 pm, to buyers who specifically sought it out. The remaining meat then made its way to restaurants and roadside food stalls near liquor shops where it was sold at much lower rates.
Around 75% of the hunters interviewed reported that they supplied birds to 426 eateries in the area. However, out of the 681 eateries surveyed, only eight acknowledged serving wild waterbird meat.
“It is significant that there is a market at work which sustains this trade and it stays under the radar,” said Ravinder Singh Bhalla of the Foundation for Ecological Research, Advocacy and Learning in Tamil Nadu. He added that hunting as a paid hobby was more prevalent than documentation suggested, since it was usually kept under wraps.
“What is remarkable is how this practice has stayed undocumented for what appears to be decades,” said Bhalla. “It would be too simplistic to attribute this to collusion by authorities alone. Social exclusion and lack of economic opportunities combined with cultural practices clearly have a role to play in this choice of livelihood by the hunters.”
Among the waterbirds that are being hunted are many migratory species, which India is bound to protect under the international Convention on Migratory Species. “Yet these are being sold on national highways,” said Ajith Kumar of the Wildlife Conservation Society. “A suitable method should be devised for controlling this, not just by forest officials harassing these communities and putting a few of them behind bars.”
Neglected field of study
The study has also brought to light the lack of research on wetland ecology, which Gopi Sundar claims is an extremely nascent science.
“Serious work that asks important questions has been largely missing,” the Nature Conservation Foundation scientist said. He pointed out that the majority of large waterbirds are found outside protected areas whereas much of ecological research is focused on protected forest areas.
So far, studies in the area of wetland ecology have dealt with ecological parameters such as the size of water bodies and vegetation, and their relationship with the populations and diversity of birds. This study is the first to have gathered information on hunting practices and factored these into trends of community structures and counts of bird species in each wetland, the researchers said. “This kind of analysis has never been done anywhere in the world,” said Gopi Sundar.
