Caratteristiche fisiche da controllare

1. 1

   Piumaggio

   Colorazione e disegno generale del piumaggio.

   Overall brown streaky plumage. Males in breeding plumage have a distinctive crimson forehead and breast, grey nape, and chestnut back. Females and non-breeding males are duller, lacking the crimson, with a buffy-brown head and streaked underparts. Both sexes have a white patch on the outer primaries and white edges to the tail feathers, visible in flight.

2. 2

   Forma del becco

   Forma e colore del becco, un segno di campo chiave.

   Conical, relatively small and pointed, adapted for seed eating. Greyish-horn color.

3. 3

   Colore degli occhi

   Colore dell'iride e segni distintivi sugli occhi.

   Dark brown.

4. 4

   Colore delle zampe

   Colore di zampe e piedi.

   Dark brown to blackish-brown.

5. 5

   Caratteristiche distintive

   Tratti distintivi che separano questa specie.

   White wing-bar (especially prominent in flight), white outer tail feathers, and the male's crimson head and breast in breeding season. The streaky brown plumage is characteristic.

6. 6

   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles are heavily streaked brown above and below, lacking any red or grey. They have a buffier tone than adult females and a less distinct wing-bar.

7. 7

   Cambiamenti stagionali

   Variazione del piumaggio tra stagione riproduttiva e non.

   Males undergo a significant change from a duller, less colorful non-breeding plumage to a vibrant breeding plumage with crimson forehead and breast. This change is primarily due to feather wear revealing the underlying color, rather than a complete molt.

8. 8

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Pronounced in breeding season: males display crimson on forehead and breast, grey nape. Females lack these colors, being duller brown overall with streaked underparts. In non-breeding plumage, males lose much of their crimson, becoming more similar to females but often retaining some reddish tinge.

Segni di campo chiave

• Size and Shape. Small, slender finch with a relatively long tail and a small, conical bill.
• Plumage (Male Breeding). Look for the striking crimson forehead and breast, grey nape, and chestnut back. Streaky brown flanks.
• Plumage (Female/Non-breeding Male). Overall streaky brown, lacking crimson. Look for the buffy-brown head and streaked underparts.
• Wing and Tail Markings. Crucial for both sexes: a prominent white patch on the outer primaries (visible in flight) and white edges to the tail feathers.
