1. 1

   Piumaggio

   Colorazione e disegno generale del piumaggio.

   Males are brightly colored with a blue-grey crown and nape, reddish-brown cheeks and breast, and a pinkish-brown belly. The back is chestnut-brown, and the rump is greenish. Wings are dark with two prominent white wing-bars and a yellow patch. The tail is dark with white outer feathers. Females are duller, predominantly olive-brown to grey-brown overall, with a paler underside and less distinct white wing-bars. Both sexes have a pale bill (bluish-grey in males, brownish in females) and dark eyes.

5. 5

   Caratteristiche distintive

   Tratti distintivi che separano questa specie.

   Key features include the prominent white wing-bars (especially two on the wing), the greenish rump (visible in flight), and the distinctive head pattern of the male. The female's overall duller plumage still shows the characteristic wing-bars and greenish rump.

6. 6

   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles resemble females but are generally duller and streakier, with less defined wing-bars. Their plumage is softer and less compact.

7. 7

   Cambiamenti stagionali

   Variazione del piumaggio tra stagione riproduttiva e non.

   Males in breeding plumage are vibrant. In non-breeding plumage (autumn/winter), the male's colors are slightly muted due to pale feather fringes, which wear off by spring to reveal the brighter breeding colors. Females show less seasonal variation.

8. 8

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Pronounced. Males are much more brightly colored with blue-grey, reddish-brown, and chestnut tones. Females are duller, mostly olive-brown and grey-brown.

Segni di campo chiave

• Size and Shape. A medium-sized, plump finch with a relatively short tail and a stout, conical bill.
• Male Plumage (Breeding). Look for the distinctive blue-grey crown and nape, reddish-brown cheeks and breast, chestnut-brown back, and greenish rump. Two prominent white wing-bars and a yellow patch on the dark wings are key.
• Female Plumage. Duller overall, olive-brown to grey-brown, but still shows the characteristic two white wing-bars and a greenish rump (though less vibrant than the male).
• Flight. Observe the undulating flight pattern and the flash of the greenish rump and white wing-bars.
• Song. Listen for the loud, rapid, and cheerful song ending with an emphatic 'tschink' or 'chick-choo-wee' flourish.
• Call. Listen for the sharp, metallic 'pink!' or 'chink!' call, especially when alarmed or in flight.
