Aldabra brush warbler
species of bird
The Aldabra brush warbler (Nesillas aldabrana) is an extinct bird in the acrocephalid warbler family. It was endemic to the atoll of Aldabra in the Seychelles and an individual was last seen in 1983.
Description
The Aldabra brush warbler was a slender bird with relatively short wings and a long, pointed tail. It reached a total length of 18 to 20 cm (7.1 to 7.9 in). The upper parts were dun and the underparts a rather paler hue. The song was never recorded but the call was a nasal, three-syllable chirrup.
Ecology
The Aldabra brush warbler was a shy and retiring bird, difficult to observe in the dense undergrowth in which it lived. It was most readily located by its chirruping call.
Discovery and extinction
The Aldabra brush warbler was discovered by British ornithologists Constantine Walter Benson, Malcolm Penny and Tony Diamond in 1967 and described in 1968 by Benson and Penny on the basis of a male, a female and a nest with 3 eggs. Juveniles were never found.

Why this record matters
“Aldabra brush warbler” is worth following because a concise public description often conceals a longer documentary argument. Here, Aldabra, brush and warbler provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q593384. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1983, 1967 and 1968.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
