Overview
Overview
The Corsican Finch is a small mountain finch endemic to the islands of Corsica and Sardinia, closely related to the Citril Finch of mainland southwestern Europe. It is generally duller and browner in tone than its mainland relative, a subtle but useful distinction for observers familiar with both species.
Like the Citril Finch, it lacks the bold black facial markings seen in siskins, presenting a plain, unmarked face alongside its muted body coloration.
Identifying the Feather
Feather Identification
- Body feathers: duller greenish-brown overall compared to the brighter yellow-green of the Citril Finch.
- Head feathers: plain and unmarked, with grey limited to the nape and hindneck.
- Wing feathers: dark with faint greenish-brown edging, lacking strong bars.
- Distinguishing from similar species: separated from the Citril Finch mainly by its duller, browner overall tone and from siskins by its lack of black facial markings.
Plumage & Molt
Plumage Details
Adults show a muted greenish-brown body plumage, duller than the brighter yellow-green of the mainland Citril Finch, with a grey nape and hindneck and dark, faintly edged wings. Sexes look broadly similar. Juveniles are more heavily streaked and duller still, gaining the adult's subdued tone after their first molt.
Habitat & Range
Habitat & Range
This species is restricted to mountainous areas of Corsica and Sardinia, occupying scrub and conifer forest habitats at higher elevations. It is largely resident on these islands, with some seasonal movement to lower elevations in winter.
Behavior & Field Notes
Behavior & Field Notes
Corsican Finches feed on small seeds, often in flocks outside the breeding season, foraging on the ground and in low vegetation. Their song is a light twittering warble similar to that of the Citril Finch. Nests are built in conifer trees at higher elevations. The overall duller, browner plumage tone compared to the mainland Citril Finch is the main feather-based clue to identification, alongside its restricted island range.
