Extremely happy to see this bird in Bangalore. It is a species of the swallow found in South Asia. Whitish below the throat and boldly streaked with brown on throat and upper breast is a clear way to identify this bird. As with other swallow species this also has a very communal roosting behavior. They are mostly found in large clusters of nesting groups around water bodies. It is erratic in its distribution but within its range it is plentiful around water bodies near cliffs or other masonry on which it can build its nests, often in the company of Sand Martins. This is classified as least concern by IUCN.
