The number of dolphins and birds is increasing continuously in Bihar Kosi, Navagachia and Kursela region. It is considered to be much better from an environmental point of view. In a recent month-long survey and census conducted from February 10 to March 16, 194 small-scale dolphins of the Ganges species in the Kosi river were found in the Saharsa and Supaul districts and Navagachia, Kursela region in the Kosi river. Which is 139 more than the number of dolphins found in the survey conducted five years ago from 28 to 31 March 2016.

Survey by boat in a distance of 260 km
At the same time, more than a hundred species of birds were also seen, including many birds considered extinct. The number of birds has also increased, only 99 species of birds were seen five years ago. This time the boat was surveyed in a distance of 260 km across the Kosi river from Nepal border to Supaul, Saharsa to Kursela. The survey team was led by Dr. Gopal Sharma, Senior Scientist and Regional Director of Zoological Survey of India Ganga Samabhoomi Territorial Center Patna. Along with him in the team were 13 scientists including Naveen Kumar, who has written a book on birds of Bihar, Dolphin and Deepak Kumar, who work in the field of biodiversity. On behalf of the Department of Forest Environment and Climate Change, there were DFOs, Range Officers and Forests of Supaul and Saharsa. Dr. Zoological Survey of India, Ganga Samabhoomi Territorial Center, Patna, preferred scientist and regional director, who led the survey team.

94 dolphins were seen during the survey
Supaul saw 30 and 94 dolphins from Navagachia to Kursela in Bhagalpur division. The dolphin was seen up to three meters long. Supaul forest division officer Sunil Kumar Sharan, who was part of the survey team, said that more than a hundred species of birds were seen. After estimating the actual number, a proposal will be sent to the state government to prepare a proposal for conservation of other aquatic organisms including dolphins in the Kosi river. He said that the dolphin, which the locals here know more than the name of Sons, was made aware of the conservation by telling the people around with respect to its characteristics and requirements of being in the river. They were told that the dolphin is the highest predator of freshwater. Whose food is small fish. There is no competition among the fishermen as they catch big fish. Fishermen have been advised and warned not to set up nets to catch the fish. If you could do it

Endangered birds like Himalayan Griffin were also found
during the survey. Endangered birds like Himalayan Griffin were also found . The scientist said that for the first time a bird named Common Shell Duck was also seen in the Kosi region. Other birds were seen, including indiger, rare indenter, big and small Garuda.

Dolphins do not jump higher than the surface
The FO stated that due to the water depth of the Kosi river, the dolphins do not jump higher than the surface. They have to come above the surface for three to four minutes to breathe. But when the dolphin went under water, it would be difficult to know where it went and at what distance it would come out again. The DFO said that the higher the number of dolphins, the cleaner the river water will be and clean. The health of the river is indicated by the number of dolphins and their tendency to roam. Its rotation also depends on the depth and the water flow of the river. Five years ago in 2016, the Department of Botany Head, Tilakamanjhi University, Bhagalpur, Prof. Sunil Kumar Chaudhary, Researcher Subhashish Dey, Dr. Brajnandan Kumar, Mayukh Dey, Nachiket Kelkar, The survey and calculation was done by Sunil Kumar, the then Saharsa DFO. Thereafter, the DFO of Saharsa and Supaul demanded the government to allocate sufficient amount of money for the protection of other aquatic organisms including dolphins, but it only ran till the file. Then the plan to preserve the file itself does not need to be taken care of.

Dr. Gopal Sharma, scientist at the Zoological Survey of India, Dehradun, who led the survey, said that a large number of dolphins and birds need to be protected to protect them from the environmental point of view. The Kosi area and the Kursela area from the Nepal border are quite inaccessible, where the forest department needs to work for the conservation of aquatic organisms.

On the other hand, Supaul Forest Divisional Officer Sunil Kumar Sharan said that a proposal will be sent to the state government to prepare a proposal for conservation of other aquatic creatures including dolphins spotted in Kosi river.
