   Adults have a slate-grey head, back, and rump. The throat and breast are black in breeding males, grey in females and non-breeding males. The belly is grey. The most striking feature is the large, rounded wings, which are primarily black with prominent crimson patches on the coverts and tertials, and two rows of white spots on the primaries. The tail is black with white tips on the outer feathers.

   Caratteristiche distintive

   Tratti distintivi che separano questa specie.

   Unmistakable crimson wing patches, long slender bill, and unique climbing behavior on vertical rock faces. The broad, rounded wings give it a butterfly-like appearance in flight.

6. 6

   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles resemble adult females, with a grey throat and breast. Their plumage is generally duller, and the crimson wing patches may be less vibrant. The white spots on the primaries are present but can be less distinct.

7. 7

   Cambiamenti stagionali

   Variazione del piumaggio tra stagione riproduttiva e non.

   Males undergo a pre-breeding molt where the throat and upper breast turn black. After breeding, a post-breeding molt returns them to the grey-throated non-breeding plumage, similar to females.

8. 8

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   During the breeding season (March-July), males have a prominent black throat and upper breast. Females and non-breeding males have a grey throat and breast, though some non-breeding males may retain some black mottling. The crimson wing patches are present in both sexes and all ages.

Segni di campo chiave

• Plumage. Look for the unique combination of slate-grey body, black wings with prominent crimson patches, and two rows of white spots on the primaries. The black throat of breeding males is also a key feature.
• Behavior. Observe its distinctive climbing style on vertical rock faces, probing crevices with its long bill. Its jerky, butterfly-like flight, often with wings spread to show the crimson, is unmistakable.
• Habitat. Search in high-altitude rocky environments, cliffs, and gorges. In winter, check lower elevation rocky areas, quarries, or large stone buildings.
• Vocalization. Listen for its clear, melancholic, fluty whistle, especially in spring and early summer. The high-pitched 'tsit' call is also characteristic.
• Bill Shape. Note the long, slender, slightly downcurved bill, perfectly adapted for extracting insects from rock crevices.
