Tenerife blue chaffinch
species of bird

The Tenerife blue chaffinch (Fringilla teydea) is a species of passerine bird in the finch family Fringillidae. It is endemic to Tenerife in Spain's Canary Islands. This bird is the natural symbol of this island, together with the Canary Islands dragon tree.
Taxonomy
Until 2015, the species Fringilla teydea was classified into two subspecies: Fringilla teydea polatzeki from Gran Canaria and Fringilla teydea teydea from Tenerife. However, a study published in March 2016 showed that a classification as different species, Fringilla polatzeki and Fringilla teydea, is justified.
Description
Tenerife blue chaffinches resemble common chaffinches, but they are noticeably larger, and have a thicker bill. They are characteristically more uniform in their plumage, and they lack a dark cap. Females are a dull grey-brown, but can be distinguished from chaffinches by their weaker wing bars. Breeding males are unmistakable, with the namesake largely blue plumage and a grey bill.

This bird is found only in the highlands of Tenerife.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Tenerife blue chaffinch”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 7, 2026. The linked authority identifier is Q847168. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2015 and 2016.
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.
