Corsican finch

The Corsican finch (Carduelis corsicana), also known as the Corsican citril finch or Mediterranean citril finch, is a species of passerine bird belonging to the family Fringillidae, the "true" finches. This species is endemic to Corsica and Sardinia and nearby islands in France and Italy.

The Corsican finch is a small finch, with a length of between 11.5 and 12.5 cm (4.5 and 4.9 in). It is very similar to the citril finch but it has a brown back marked with dark streaks and the yellow underparts and face have less of a green tinge than seen in the citril finch. It also has greyish rather than olive uppertail coverts. The colours of the females are duller than the males.

The Corsican finch has vocalisations similar to those of the citril finch but the flight call has been described as weaker and moretremulous while the song is longer, with more structure and has been compared to that of a Eurasian wren (Troglodytes troglodytes).
