Nestled in the foothills of the Himalayas, Rajaji National Park is a verdant paradise teeming with a rich diversity of flora and fauna. Among its many avian inhabitants, the Grey-throated Martin, also known as the Plain Martin (Riparia chinensis), stands out as a delightful sight for bird watchers and nature enthusiasts.
It is a small, agile bird belonging to the swallow family. It is easily recognizable by its modest brown and grey plumage, which might seem plain at first glance but reveals intricate patterns upon closer inspection. This bird is known for its graceful flight, often seen skimming over water bodies or fields in search of insects.
Physical Characteristics

Habitat and Distribution
It is widely distributed across South Asia, including India, Sri Lanka, and parts of Southeast Asia.

Rajaji National Park, with its varied terrain of forests, grasslands, and riverine areas, provides an ideal habitat for these birds.
The Grey-throated Martin and Northern House-Martin share a habitat similarity in their preference for open areas near water bodies. Both species are often found in regions with rivers, lakes, or wetlands, where they can easily access their primary food source—flying insects. These martins also favor habitats with suitable structures, such as cliffs, buildings, or bridges, where they can build their nests. This shared affinity for open, water-adjacent environments allows them to thrive in similar ecological niches, often coexisting in the same regions where these conditions are met.
Sanctuary for Wildlife
Spanning over 820 square kilometers, Rajaji National Park is a haven for wildlife enthusiasts. The park’s diverse ecosystem supports a plethora of species, from majestic elephants and elusive leopards to a wide array of birds, including the Grey-throated Martin. The park’s Ganga and Song rivers create an ideal environment for these birds, offering ample feeding and nesting opportunities.
Behavior and Diet
They are aerial insectivores, meaning they catch their prey in flight. Their diet primarily consists of flying insects like bees, wasps, and ants. They are often seen flying low over water or open fields, showcasing their impressive aerial acrobatics.
Social Structure
These birds are social and often found in small flocks, especially during the breeding season. They are known to be quite vocal, communicating with a series of chirps and calls that can be heard as they flit about their territory.
Breeding and Nesting
The breeding season for the Grey-throated Martin typically aligns with the monsoon, from May to August. They are cavity nesters, preferring to build their nests in burrows dug into sandy banks or cliffs near water bodies. The female lays a clutch of 3-5 eggs, which are incubated for about two weeks before hatching.
Conservation Status
Currently, they are listed as Least Concern on the IUCN Red List. However, habitat destruction and pollution pose significant threats to their populations. Efforts to preserve natural habitats, such as those undertaken in Rajaji National Park, are crucial for their continued survival.
