Bhagalpur: The sighting of endangered Indian Skimmer birds along a 60-km stretch of the Ganga between Sultanganj and Kahalgaon under the Vikramshila Gangetic Dolphin Sanctuary (VGDS) in Bhagalpur district after nearly 20 years has highlighted significant improvement in the river's ecological health.
Known for their distinctive elongated lower beaks and low-flight fishing technique, Indian Skimmers (Rynchops albicollis) are considered an important indicator of healthy freshwater ecosystems with clean water and abundant fish population.
Return of a Keystone Species
In a post on X on Monday, the National Mission for Clean Ganga stated that the birds survive only in river stretches where the water quality remains good. The post emphasized that the return of the endangered species to the Vikramshila Gangetic Dolphin Sanctuary after nearly two decades reflects a positive shift in the ecological condition of the Ganga in the region.
The reappearance of Indian Skimmers in Bhagalpur was described as an encouraging local milestone and indicates improvement in the water quality of the river over the years. This development has been widely welcomed by bird watchers and nature conservationists, who see it as a positive sign for biodiversity conservation and river ecosystem restoration in Bihar.
Ecological Significance
Indian Skimmers are highly sensitive to pollution and habitat degradation. Their presence suggests that the Ganga's water quality has improved sufficiently to support a diverse fish population, which is crucial for the species' survival. The Vikramshila Gangetic Dolphin Sanctuary, already known for its population of endangered Gangetic dolphins, now adds another rare species to its list of inhabitants.
Conservationists hope that this trend will continue, leading to further restoration of the river's ecosystem. The sighting also underscores the importance of sustained efforts in river conservation and pollution control measures implemented under the National Mission for Clean Ganga.
Local and Global Implications
The return of Indian Skimmers is not just a local achievement but also contributes to global conservation goals for this vulnerable species. According to the International Union for Conservation of Nature (IUCN), the Indian Skimmer is listed as Endangered, with populations declining due to habitat loss, pollution, and disturbance. The successful revival of their habitat in the Ganga could serve as a model for other river restoration projects across the country.
Local communities in Bhagalpur have also expressed delight at the sighting, with many hoping that it will boost eco-tourism in the region. The sanctuary, which spans over 60 kilometers, offers a unique opportunity for bird watchers and nature enthusiasts to observe these rare birds in their natural habitat.
