Migratory birds that usually depart Prayagraj's Triveni Sangam by February are still staying

Scientists astonished
Experts believe this is a proof of Sangam’s pure water and clean air.

Prayagraj (Uttar Pradesh) – Every year, thousands of migratory birds from colder regions like Russia, Siberia and Poland arrive at the sacred Triveni Sangam in Prayagraj by late December. Typically, these birds leave by the end of February, but this year, they have extended their stay until March 13. Scientists are astonished by the large number of migratory birds still present, even 15 days after the conclusion of Maha Kumbh festival. Ornithologists and biologists believe that this prolonged presence is the strong evidence of Sangam’s clean water and pure air, indicating a high level of environmental purity. Ornithologist Dr. Sandeep Malhotra notes that the continued presence of one of Larus Ridibundus species is a key indicator of unpolluted water and clean air. These birds naturally remain only when aquatic life is thriving and the atmospheric conditions are favorable. Their extended stay suggests that the efforts to maintain the purity of the Ganga during Maha Kumbh festival have been successful.

Increase in the number of Dolphins in the Ganga

A report by the Uttar Pradesh Pollution Control Board confirms that the water and air quality around the Sangam area has significantly improved. The rising population of Dolphins in Ganga serves as strong evidence of the river’s cleanliness. According to a report published by the Ministry of Environment on the World Wildlife Day (March 3, 2025), the number of Dolphins in the Ganga has increased from approx. 3,275 in 2021 to 6,324. This growth is particularly evident in the river’s flow around Prayagraj and Patliputra, further indicating a substantial improvement in the water quality of the Ganga.

Scientists satisfied by the rising dolphin population

Environmentalists and ornithologists assert that maintaining the purity of water and air in the Sangam region would greatly benefit biodiversity. The growing number of birds and dolphins in the Ganga confirms a significant improvement in Prayagraj’s overall environmental quality.

Impact of efforts taken during Maha Kumbh Festival

During the 2025 Maha Kumbh festival, both the state and central governments launched special initiatives to clean the Ganga and control pollution. Under the program ‘Namami Gange’, strict measures were enforced to prevent sewage discharge into the river. The impact of these efforts is now evident. Scientists believe that if this progress continues, the Ganga will become even cleaner in the future.

Need to sustain the cleanliness initiative in the future

Scientists believe that the government must continue its efforts to maintain water cleanliness. Even after the Maha Kumbha festival, strict implementations of wastewater treatment projects, garbage disposal systems, and pollution control measures for the Ganga are essential. Only then can this progress be sustained in the long run.
