20-10-2020 SIERRA DE ESPUNA, MURCIA - RED CROSSBILL (MALE) (Loxia curvirostra)


The Red Crossbill, known as Loxia curvirostra, is a small passerine bird belonging to the finch family Fringillidae. This species exhibits a unique adaptation: its mandibles, which cross at the tips, are specialized for extracting seeds from conifer cones and other fruits. Adult males typically display vibrant red or orange plumage, while females are adorned in shades of green or yellow. However, there is considerable variation in both beak size and shape, as well as call types, across its range.

The Red Crossbill is readily identified by its distinctive crossed mandibles, a feature that sets it apart from most other bird species. However, it shares this characteristic with the similar Two-barred Crossbill. The Red Crossbill can be distinguished by its uniformly brownish-black wings, lacking the bright white wing bars present in the Two-barred Crossbill. While there are other closely related crossbills within its range, such as the Parrot, Scottish, and Cassia Crossbills, these are best identified by their calls, as visual differences are minimal.
