When a species is isolated and population numbers reduced evolution takes a hand. It sculptures the appearance and sound of a species and gradually changes it to be different form the original.
Here in the Canaries our familiar birds all take on a different guise. They are familiar, but different.
The Chaffinch has altered colours, the Chiffchaff has a song more like a Cetti’s and the Blue Tit has lost wingbars but gained a blueness about it that would make any self-respecting brit tit green with envy. The Goldcrest has a thinner less strident song and an unfamiliar face pattern. The Robin is less of a redbreast and more of a red-throat and has gained grey flanks and it has to be said a more melodic song. Even the Great spotted Woodpeckers pale underparts have been sullied into a greyer plumage. All sub species; species in the making.

Tenerife Goldcrest or is it a race of Firecrest … authorities disagree as to its status.
