6. 6

   Aspetto giovanile

   Come i giovani si differenziano dagli adulti.

   Juveniles have a mottled white and cinnamon-brown plumage, particularly on the head and neck, which gradually whitens with age. The red crown patch is absent or very dull in juveniles, developing fully after several years. Their flight feathers are often brownish-black rather than pure black.

   Cambiamenti stagionali

   Dimorfismo sessuale

   Differenze tra maschi e femmine.

   Males and females are generally similar in plumage. Males tend to be slightly larger than females, but this difference is not easily discernible in the field. The red crown patch may appear slightly larger and more intense in males during courtship displays.

Segni di campo chiave

• Plumage. Look for the striking contrast of pure white body feathers against the jet-black neck, face, and primary/secondary flight feathers. This pattern is unique among cranes in its range.
• Red Crown. The most distinctive feature is the patch of bare red skin on the crown. Its intensity can vary, but it's always present in adults. In juveniles, it's absent or very dull.
• Size and Stature. It is one of the largest crane species, with an imposing height and wingspan. Its elegant, upright posture is characteristic.
• Vocalizations. Listen for its loud, trumpeting calls, especially the synchronized unison call of a pair, which is a key identifier in its habitat.
• Behavior. Observe its elaborate courtship dances, involving bowing, jumping, and wing flapping, which are unique and highly visible.
