Willie wagtail
species of bird

The willie wagtail (Rhipidura leucophrys) (also spelt willy wagtail) is a passerine bird native to Australia, New Guinea, the Solomon Islands, the Bismarck Archipelago, and Eastern Indonesia. It is a common and familiar bird throughout much of its range, living in most habitats apart from thick forest. Measuring 19–21.5 cm (7+1⁄2–8+1⁄2 in) in length, the willie wagtail is contrastingly coloured with almost entirely black upperparts and white underparts; the male and female have similar plumage.
Three subspecies are recognised; Rhipidura leucophrys leucophrys from central and southern Australia, the smaller R. l. picata from northern Australia, and the larger R. l. melaleuca from New Guinea and islands in its vicinity. It is unrelated to the true wagtails of the genus Motacilla; it is a member of the fantail genus Rhipidura and is a part of a "core corvine" group that includes true crows and ravens, drongos and birds of paradise. Within this group, fantails are placed either in the family Dicruridae, alongside drongos, or in their own small family, Rhipiduridae.
The willie wagtail is insectivorous and spends much time chasing prey in open habitat. Its common name is derived from its habit of wagging its tail horizontally when foraging on the ground.
Begin with the source’s own compact description: “Willie wagtail” is species of bird. The dossier treats that line as a proposition to test through Willie, wagtail 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q642235. The Library of Congress control number is sh85146799. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
