Source-derived summary

The white-tailed swallow (Hirundo megaensis) is a small swallow belonging to the family Hirundinidae and is endemic to Oromia, Ethiopia. It is commonly referred to as "Benson's swallow" after the ornithologist Constantine Walter Benson, who described the species. This small bird is classified as a vulnerable species by the International Union for Conservation of Nature (IUCN), as there is a progressive declination of the species which now consists of less than 10,000 adult individuals worldwide. It has a surprisingly small range for a swallow, as it is wholly dependent on a cooler "bubble" surrounding its small range, likely for proper breeding success. It is one of the most threatened bird species by climate change and a massive range reduction is projected in the future.

Description

The white-tailed swallow is a small bird that measures about 13 cm (5.1 in) in length. It is named for its distinct white underbelly which runs from the throat to the tail. The top of the bird's body, including its head, wings, and back, is mostly blue. The tail is slightly forked. It consists of short, white feathers and long, darker feathers on the edges, called rectrices, that are used for greater balance and steering while in flight.

Editorial summary

“White-tailed swallow” enters the record as species of bird. Crown Archives preserves that source wording while asking what White-tailed, swallow and species can confirm, complicate or overturn.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current 203-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around White-tailed, swallow and species.
Editorial analysis

Why this record matters

“White-tailed swallow” is worth following because a concise public description often conceals a longer documentary argument. Here, White-tailed, swallow and species provides the most credible route into that argument.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated May 6, 2026. The linked authority identifier is Q629675.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
