The scarlet rosefinch (Carpodacus erythrinus) hides and makes its nest in shrubs, similarly to warblers. Females and young males are modest, brownish birds with sturdy beaks, lacking any clear distinguishing characteristics. At two years old, the male’s plumage turns into an impressive, scarlet colour.
Their song is whistle-like and easy to identify. The males sing from prominent perches, which is the best time for spotting them with binoculars. The scarlet rosefinch is a summer bird that arrives in Finland in late May and leaves as early as August.
