Analysis: Migratory birds flocking to DEring Wildlife Sanctuary

Migratory Birds Return to Daying Ering Wildlife Sanctuary

The arrival of migratory birds at the Daying Ering Wildlife Sanctuary (DEWS) in East Siang district has sparked excitement among wildlife enthusiasts. This annual phenomenon, which brings a diverse array of birds to the region, is a significant event that underscores the sanctuary's importance as a crucial stopover for these winged visitors.

Birds Spotted in the Sanctuary

Wildlife officials have reported sightings of various migratory birds, including the Ruddy Shelduck (Tadorna ferruginea), Great Cormorant (Phalacrocorax carbo), Black-bellied Tern (Sterna acuticauda), and other smaller species. These birds have been spotted in the Borguli and Sibiyamukh ranges of the wildlife sanctuary.

Delayed Arrival of Migratory Birds

Typically, winter migratory birds begin arriving at DEWS and the river basins of the Siang and Lali rivers from mid-November to early December every year. However, this year, they started arriving only in the last week of December. This delay might be due to unpredictable weather patterns or other factors affecting their migration route.

Significance of DEWS for Migratory Birds

Located near Pasighat town, DEWS is sandwiched between the Siang and Sibya rivers, creating an ideal habitat for wildlife. The sanctuary, with its pristine water bodies and sandbars, provides favorable ecological conditions for avian visitors, serving as a crucial stopover during their migration. This factor plays a significant role in maintaining the ecological balance of the Siang valley.

Globally Threatened Species in DEWS

Notably, the wildlife sanctuary is home to some globally threatened avian species, including endangered vultures and the Bengal Florican (Houbaropsis bengalensis). The presence of these species highlights the sanctuary's importance in conserving biodiversity and maintaining the health of the Siang valley's ecosystem.

Relevance to North East Region and India

The return of migratory birds to DEWS is a testament to the region's rich biodiversity and the importance of preserving its wildlife habitats. As the Siang valley experiences rapid development, it is crucial to strike a balance between economic growth and conservation efforts to ensure the survival of these precious species and the health of the ecosystem.

Looking Forward

As the number of migratory birds increases in the coming weeks, visitors and wildlife enthusiasts are eagerly awaiting the opportunity to witness this natural spectacle. Meanwhile, conservation efforts will continue to ensure the sanctuary remains a welcoming haven for these winged travelers, contributing to the region's rich biodiversity and the health of its ecosystem.
