For three years, 24-year-old Yimkongangba, a self-taught wildlife photographer from Longleng, Nagaland, has been studying Pterorana khare, the Indian flying frog. His research has now led to a significant discovery—confirming a second known habitat for the species in Nagaland, at the Yaongyimchen Community Biodiversity Conservation Area (YCBCA).

“Pterorana khare is a rare species found in only six to nine known locations, mainly in Mizoram and Nagaland,” Yimkongangba explained. “Even in Nagaland, it was only known to exist in one place—the Sanuoru River in Kohima. But after my research, we now have two known locations in Nagaland.”
His journey to identifying the species was not easy. “It took me two and a half years to confirm it,” he told MT. “But with help from anthropology, we were able to confirm the species tag.”
“I have studied this species for over three years. During December and January, some hibernate, slowing down their activities, while they spawn in large numbers during November. However, there seems to be a lack of information on the species, apart from its original description, which was done in 1986,” he added.

However, he lamented the lack of dedicated research on the species. “Unless someone specifically studies this species, we may never fully understand its behavior. But I believe that the northeastern part of Nagaland has much more to offer in terms of biodiversity.”
Chasing a Passion for Wildlife
Yimkongangba’s journey into wildlife photography and research was unconventional. “Back in 2014, I fell in love with a booklet of photographs from an NGO. At that time, I never knew I would chase what I loved,” he recalled.
By 2017, he made a bold decision—dropping out of high school to pursue wildlife photography. “I started with my very old DSLR and learned everything through YouTube and other sources,” he shared.
In 2019, he completed professional photography training and began conducting research and birding. To sustain his passion, he also took up commercial photography. “I do commercial work, but everything I earn, I invest back into wildlife,” he said.
He hopes his work will encourage more researchers to study the Indian flying frog and other lesser-known species in Nagaland. “I want to continue, but independent research is tough. More support is needed,” he admitted.
In his pursuit of wildlife conservation, Yimkongangba emphasized the need for greater support. “Through this research, I’m seeking attention and financial support from the DFO, the Wildlife Department, and any other individuals interested in wildlife conservation and rare species,” he stated.
