The Teydefink ( Fringilla teydea ), also Teidefink , is a songbird belonging to the family of finches (Fringillidae) . It was named after the highest mountain on the island of Tenerife , the stratovolcano Teide , and is the animal symbol of the island of Tenerife.
features
With a length of 16 to 18 centimeters, the Teydefink is visibly larger than the chaffinch . The beak, head and chest are stronger than those of the chaffinch.
The drawing of the plumage is inconspicuous. The wings have two narrow, gray-white bands that are created by the light-colored ends of the middle and large arm covers. The dark tail does not contain white.
The male has a blue-gray head and coat (upper back), the throat, chest and flanks are lighter lead-gray. The under tail-coverts are white. The female has a brown-gray upper side and a gray-white underside.
distribution
The Teydefink is an endemic species of bird of the island of Tenerife. It is considered potentially endangered and has been under protection in the Canary Islands since 1980. The small population on Gran Canaria has traditionally been viewed as the subspecies Fringilla teydea polatzeki . However, recent research from 2016 suggests that this should be outsourced as an independent species, Fringilla polatzeki . The (sub) species is classified as critically endangered due to its rarity.
The Teydefink is the sister species of the chaffinch.
voice
The call is a two-syllable "tjrooit" with a slightly squeaky sound. The singing is shorter and less powerful than the chaffinch and slows down towards the end. It consists of several descending and somewhat rough-sounding tones, the last of which is drawn out. For example "sitt-itt-sitt-rüha-rüha-rrüüAAH".
habitat
The habitat are pine forests. In these the brood takes place at an altitude of 1200 to 1800 meters. The foraging for food also takes place in pine forests, partly on mountain slopes with dense bushes, in hard winters also in cultivated landscapes down to 500 meters.
