Nepal is known for its breathtaking natural beauty, attracting nature enthusiasts from around the world every year. Among the diverse flora and fauna of Nepal, one fascinating bird species deserving attention is the Long-toed Stint (Calidris subminuta). In this article, we'll delve into the details of this remarkable species and its presence in the vibrant ecosystem of Nepal.
Introduction to the Long-toed Stint
The Long-toed Stint is a small migratory wading bird belonging to the family Scolopacidae. Measuring 13-15 cm in length and weighing around 20-40 grams, it has a wingspan of 29-33 cm. This species can be easily recognized by its long, slender legs - that range between yellowish-green to grayish hues - and distinctive long toes that provide them with a unique advantage while searching for food in shallow waters.
Distribution and Habitat
The breeding range of the Long-toed Stint stretches from Siberia to northeastern China and Mongolia. In winter, they migrate to Southeast Asia, Australia, Papua New Guinea, Indonesia, and other Pacific Island nations. They are also seen stopping over in Nepal during their migratory journey. This bird species favors wetlands such as marshes, swamps, ponds, and shallow lakes for nesting and feeding.
Presence in Nepal
Nepal is an important stopover site for various migratory birds including the Long-toed Stint. These birds can be spotted in different wetland areas across Nepal like Chitwan National Park, Koshi Tappu Wildlife Reserve, Taudaha Lake near Kathmandu Valley, Jagdishpur Reservoir in Kapilvastu District, and Ghodaghodi Lake situated in Kailali District. Birdwatchers should visit these locations between the months of September and May to increase their chances of observing the Long-toed Stint.
Diet and Behaviour
The Long-toed Stint primarily feeds on aquatic insects, small crustaceans, mollusks, and worms. Their long toes enable them to walk over floating vegetation in search of food. They are known to be solitary while feeding but tend to flock with other waders during migration. An interesting aspect of their behavior is that they often bob their heads while walking, which resembles the movements of a sewing machine.
Conservation Status
As per the International Union for Conservation of Nature (IUCN) Red List, the Long-toed Stint is classified as a species of 'Least Concern' due to its wide distribution and stable population size. However, habitat loss due to human activities such as land reclamation, pollution, and urbanization poses a threat to the species. Conservation efforts are necessary to maintain Nepal's role as an essential stopover site for this enchanting bird.
In conclusion, the Long-toed Stint (Calidris subminuta) is a captivating bird species that enrich Nepal's ecosystem. Visitors to Nepal's wetland areas have a unique opportunity to catch a glimpse of these fascinating birds during their migratory journey. As we continue to appreciate and protect our natural environment, we preserve the existence of such charming wildlife for future generations to enjoy.
