Erica arborea
The citril finch ("Carduelis citrinella") differs from the Corsican finch ("C. corsicana") in habitat selection. While the mainland citril finch is rather restricted to subalpine coniferous forests and Alpine meadows, the insular Corsican finch may be found in different habitats from sea level to the highest mountain slopes. The citril finch nests mainly in conifers such as pines ("Pinus") and spruces ("Picea") while the Corsican finch uses also lower bushes such as tree Heath ("Erica arborea"), juniper ("Juniperus") and bramble ("Rubus").
