Adult females are similar to males but often have a rufous wash on the breast and sometimes a slightly browner tone to the grey.

Segni di campo chiave

• Call. The male's distinctive 'cuck-oo' call is the most reliable and often the first sign of its presence. Listen for the two-note call, with the first note higher.
• Flight. Observe its flight pattern: direct, strong, with rapid wing beats followed by glides, often resembling a small raptor. Look for pointed wings and a long, wedge-shaped tail.
• Plumage (Adult Male/Female). Look for grey upperparts (head, back, wings, tail) and white underparts with fine, dark barring. The tail is dark with white spots on the outer feathers. Yellow eye-ring and legs are also key.
• Plumage (Hepatic Female). If present, note the rufous-brown plumage with dark barring all over, including the upperparts. This morph is less common but distinctive.
• Plumage (Juvenile). Identify juveniles by their dark brown or rufous-brown upperparts with heavy black barring and a prominent white nape patch. They also have a dark iris.
• Behavior. Watch for its habit of perching conspicuously on branches or wires, often in open areas, before flying off to forage or call.
