Taxonomy

Until 2015 the species Fringilla teydea was classified in 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, Frigilla polatzeki and Fringilla teydea, is justified.[3]

Description

Pinzón azul de Gran Canaria (hembra), M. A. Peña
Female

Blue chaffinches resemble common chaffinches, and are a smaller in size than Tenerife blue chaffinches. Other differences are that they have two white bands in the wings very marked, a whiter belly, or less blue shades.

Females are a dull grey-brown.

Distribution

This bird is found only in the highlands of Gran Canaria, mainly in the Inagua Natural Reserve. The species' primary habitat is mountain Canary Island pine (Pinus canariensis) forest in 1.000 m. It is most common in coniferous forest areas with dense, old trees.

Behavior

It primarily eats Canary Island pine seeds. Like the common chaffinch, but, unlike most other finches, its young are fed extensively on insects. Breeding from the end of April to late July or early August, it builds a nest from pine needles and broom branches, and lays two eggs. This bird is not migratory.

In danger of extinction

The Gran Canaria blue chaffinch is one of the most endangered species of birds on the planet.[4] Unlike the Tenerife blue chaffinch which has a much wider distribution and by that island population,[5] the species of Gran Canaria has an extremely smaller population and is restricted to the area of pine forest of Ojeda, Inagua and Pajonales.[6]

Fringilla

The genus Fringilla is a small group of finches from the Old World, which are the only species in the subfamily Fringillinae. The genus name Fringilla is Latin for "finch".The four species are:

The common chaffinch is found primarily in forest habitats, in Europe, North Africa, and western Asia; the blue chaffinch is an island endemic; and the brambling breeds in the northern taiga and southern tundra of Eurasia.The three species are about the same size, 15 centimetres (5.9 in) in length, and are similar in shape. They have a bouncing flight with alternating bouts of flapping and gliding on closed wings. They are not as specialised as the other finches, eating both insects and seeds. While breeding, they feed their young on insects rather than seeds, unlike the other finches.In 2016 it was proposed that the extremely rare Gran Canaria subspecies F. teydea polatzeki be treated as a separate species, thus creating a fourth species, F. polatzeki.
