Whereas adults of the nominate race have a broad dark bluish-black breast band, this subspecies has an incomplete breast band, in which the rufous colour of the forehead, chin and throat is partly extended. In addition to the bluish-black upperparts, the rufous colour of
the forehead, chin and throat, and the off-white underparts of the nominate
race, Hirundo rustica gutturalis also
have pinkish-buff lower underparts.
