Fringilla teydea polatzeki
E. J. O. Hartert, 1905,
Until recently considered conspecific with F. teydea, but initial molecular evidence#R precipitated an integrative study#R also demonstrating minor plumage, medium morphometric and major vocal distinctions: differs mainly by its often more distinct velvet-black band above bill-base (ns); much paler, virtually white, tips to wing-coverts and more white on belly and flanks (2); paler, greyer blue on upperparts and breast (1); smaller size (effect size for male wing based on published data#R –3.69, score 2); higher frequency range in song (effect size on published data#R 4.22, score 2); and greater frequency change from start to end of first phase of song (effect size on published data#R 9.11, score 3). A score of 11 was reached by independent assessors#R. Monotypic.
