Willow tit
species of bird
The willow tit (Poecile montanus) is a passerine bird in the tit family, Paridae. It is a widespread and common resident breeder throughout temperate and subarctic Europe and across the Palearctic. The plumage is grey-brown and off-white with a black cap and bib. It is more of a conifer specialist than the closely related marsh tit, which explains its breeding much farther north. It is resident, and most birds do not migrate.
Taxonomy
The willow tit was described in 1827 by the Swiss naturalist Thomas Conrad von Baldenstein under the trinomial name Parus cinereus montanus. The type locality is the mountain forests in the Canton of Grisons, Switzerland. The willow tit is now placed in the genus Poecile that was erected by the German naturalist Johann Jakob Kaup in 1829. The genus name, Poecile, is the Ancient Greek name for a now unidentifiable small bird, and the specific montanus is Latin for "of the mountains".
Poecile was at one time treated as a subgenus within the genus Parus but molecular taxonomic analysis, using both nuclear and mitochondrial genes, supports Poecile as a distinct clade.
This brief starts where responsible research should: with the source description of “Willow tit” as species of bird. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of bird. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 22, 2026. The linked authority identifier is Q215211. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1827 and 1829.
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.
