Source-derived summary

The long-tailed tit or long-tailed bushtit (Aegithalos caudatus) is a common bird species belonging to the bushtit family found throughout Eurasia. An insectivore, it inhabits deciduous and mixed woodlands as well as scrub, heathland, farmland, parks and gardens. The plumage of this small long-tailed bird is predominantly black and white with varying amounts of pink and grey. Northern subspecies are paler and have completely white heads, lacking the large dark eyebrows of southern populations. It is a social bird that forms compact family flocks of six to seventeen individuals outside of the breeding season, when these flocks break up. It has a strong preference for nesting in scrub areas and often builds its nest in thorny bushes less than 3 metres (10 feet) above the ground.

Taxonomy and systematics

The long-tailed tit was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Parus caudatus. The current genus name Aegithalos was a term used by Aristotle for some European tits, including the long-tailed tit. The specific epithet caudatus is the Latin word for "tailed". Linnaeus did not invent this Latin name.

Editorial summary

Begin with the source’s own compact description: “Long-tailed tit” is species of songbird in the bushtit family,the Aegithalos genus. The dossier treats that line as a proposition to test through Long-tailed, species and songbird, not as a finished interpretation.

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 lead gives the account dated anchors—1758—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Long-tailed, species and songbird is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “species of songbird in the bushtit family,the Aegithalos genus” 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.

Evidence profile

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 Sep 9, 2026. The linked authority identifier is Q170831. The Library of Congress control number is sh98007367. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1758.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
