About the White-rumped Swallow
The white-rumped swallow is a species of bird in the family Hirundinidae. First described and given its binomial name by French ornithologist Louis Pierre Vieillot in 1817, it was for many years considered a subspecies of the Chilean swallow. The species is monotypic with no known population variations. It has a white supraloral streak, or streak above its lores, which can be used to differentiate it from the Chilean swallow. The lores, ear coverts, tail, and wings are black, with white tips on the inner secondaries, tertials, and greater coverts of the wings. The rest of the upperparts are a glossy blue.
