Ranges calculated from the profiles that record the figure, not from all 4.
Each one has its own full profile. This group does not replace them: it brings them together.
1 species in this group is in a threatened category according to the IUCN.
Recorded in 47 countries. The ones with the most species in the group:
It is the official animal symbol of the island of Tenerife by law of the Canary Islands Government, alongside the dragon tree as the plant symbol.
From
Its chicks feed exclusively on insects, unlike those of other finches: the adults eat Canary Island pine seeds but do not give them to their young.
From
Its probable origin is an ancient invasion of common chaffinches arriving from Africa that evolved in isolation on Tenerife.
From
It is famous for its "rain call", a series of repeated notes often given before rain.
From
It has marked regional song dialects, learned culturally from neighbouring adults.
From
It eats insects and caterpillars in summer, and seeds, grain and berries the rest of the year.
From
It is the only one of Darwin's finches outside the Galápagos, and its history is the reverse of its relatives': where they split into more than a dozen specialised species, it remained a single one that exploits every resource.
