The Streak-throated Swallow (Hirundo fluvicola) is a remarkable bird species that can be found in various habitats across Asia, from India to Southeast Asia. Recently, the presence of this unique swallow has been documented in Nepal, attracting bird enthusiasts and researchers alike. In this article, we'll dive into the essential details about the Streak-throated Swallow and explore its presence in Nepal.
An Introduction
Belonging to the family Hirundinidae, the Streak-throated Swallow is a small-sized bird with a distinctive appearance. It has a brownish-grey upper body, characterized by dark streaks on its pale underparts. The distinguishing feature of this swallow is the prominent brown streak running down its throat. With a length of approximately 15-16 cm and an average wingspan of 32-33 cm, these agile fliers are well-adapted to their aerial lifestyle.
Habitat and Diet
Streak-throated Swallows thrive in a variety of habitats. They are commonly found near open areas such as grasslands, wetlands, agricultural lands, riverbanks, and even human settlements. These birds prefer to live close to water bodies as swarms of insects are readily available, which form their primary diet. They feed on flying insects like flies, beetles, ants, and termites caught in mid-air during their swift flights.
Breeding and Nesting
The breeding season for Streak-throated Swallows varies depending on their geographical location. Generally, it ranges from February to August. They build nests made of mud pellets mixed with plant material which are meticulously constructed under bridges, culverts or rock ledges. These cup-like structures often have tunnel-shaped entrances that protect them from predators and adverse weather conditions. Females lay 2-4 eggs that are incubated by both parents. The chicks fledge in around 18-20 days, after which they become independent.
Presence in Nepal
Being primarily concentrated in India and Sri Lanka, sightings of Streak-throated Swallows outside these countries have been uncommon. However, recent observations and documentation of this swallow species in Nepal has sparked excitement among the birdwatching community.
The presence of Streak-throated Swallows in Nepal is attributed to the country's diverse terrain and habitats that support hundreds of bird species. With an increasing number of dedicated birdwatchers exploring the beautiful landscapes of Nepal, it is likely that many more fascinating discoveries await in the future.
In conclusion, the Streak-throated Swallow is a captivating bird that displays versatility in its habitat preferences and adaptability to varying conditions. The recent discovery of their presence in Nepal has shed light on this elusive species, inspiring nature enthusiasts to appreciate the rich biodiversity found within this region.
