Grey noddy
species of bird

The grey noddy or grey ternlet (Anous albivitta) is a seabird belonging to the family Laridae. It was once regarded as a pale morph of the blue noddy (Anous ceruleus) but is now usually considered to be a separate species.
Taxonomy
The first formal description of the grey noddy was by the French ornithologist Charles Lucien Bonaparte in 1856 under the binomial name Procelsterna albivitta. The specific name albivitta is from the Latin abus for "white" and vitta for "band" or "head-band".
The grey noddy was formerly placed in the genus Procelsterna. A molecular phylogenetic study published in 2016 found that the five noddies formed a single clade with the grey noddy and blue noddy in Procelsterna nested within the species in the genus Anous. The authors proposed that the noddies should be merged into a single genus Anous and that Procelsterna should be considered as a junior synonym.
Three subspecies are recognised:
A. a. albivitta (Bonaparte, 1856): Lord Howe, Norfolk and Kermadec Islands, Tonga
A. a. skottsbergii (Lönnberg, 1921): Henderson, Easter, and Isla Salas y Gómez Islands (west of Chile)
A. a.
Begin with the source’s own compact description: “Grey noddy” is species of bird. The dossier treats that line as a proposition to test through Grey, noddy and species, not as a finished interpretation.
Why this record matters
The phrase “species of bird” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 4, 2026. The linked authority identifier is Q62575749. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1856, 2016 and 1921.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. 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.
