Until late into my profession as a naturalist, I had solely heard this frog in movies posted on-line. Three years in the past, round this time, I obtained a possibility from WWF-India to work on a publication on the wetlands of Keoladeo National Park (previously referred to as Bharatpur Bird Sanctuary) in Rajasthan.
