Context: The Bombay Natural History Society (BNHS), with the Indian Army and local authorities, has sterilized over 2,950 free-ranging dogs in Ladakh since 2022 to reduce predation on the vulnerable Black-necked Crane and its chicks.
About The Black-necked Crane:
What It Is?
- The Black-necked Crane (known locally as Thrung Thrung Karmo in Dzongkha and Cha Tung-Tung in Ladakhi) is the only exclusively alpine species among the world’s 15 crane species. It serves as the official State Bird of the Union Territory of Ladakh.
Habitat & Distribution:
- Breeding Grounds: High-altitude alpine bog meadows, lacustrine marshes, and riverine wetlands at elevations between 2,600 and 4,900 meters above sea level.
- Wintering Grounds: Lower-altitude river valleys and agricultural fields (1,900–3,800 meters) in Bhutan (Phobjikha, Bumdeling), southwestern China, and parts of Arunachal Pradesh (Sangti and Zimithang valleys).
- Range Countries: Native across four countries—India, China, Bhutan, and Nepal.
IUCN Red List Status: Near Threatened (NT).
Key Characteristics:
- Distinct Plumage & Morphology: Adults feature an ashen-grey body plumage, an entirely black neck and tail, long black legs, and a prominent bare red crown on the head with a small white patch behind each eye.
- Exclusively High-Altitude Breeder: It is the only crane species in the world that carries out its entire breeding cycle exclusively in high-altitude Trans-Himalayan and Tibetan wetlands.
- Lifelong Monogamy & Courtship: Pairs mate for life and defend their breeding territories aggressively through synchronized trumpeting duets and graceful courtship displays.
- Wetland Island Nesting: Builds mound nests surrounded by shallow wetland water or mudflats to create natural barriers against terrestrial predators.
- Omnivorous Alpine Diet: Forages on plant roots, tubers, aquatic grasses, fallen post-harvest grains (barley, buckwheat, wheat), along with insects, earthworms, small fish, frogs, and lizards.
Ecological Significance:
- Revered in Ladakh and Bhutan as a symbol of peace, longevity, and good fortune, with deep roots in Himalayan traditions.
- Its presence indicates healthy high-altitude wetlands; conserving its habitat also protects freshwater ecosystems and pastoral livelihoods.
