Tanda lapangan kunci

• Call. The male's distinctive 'cuck-oo' call is the most reliable and often the first sign of its presence. Listen for the bubbling call of the female.
• Flight Silhouette. Observe its flight. It has a hawk-like silhouette with pointed wings and a long, wedge-shaped tail. It often flies with rapid wing beats followed by glides.
• Plumage (Adult Male). Look for uniform slate-grey upperparts, head, and chest, contrasting with white underparts finely barred with black. Yellow eye-ring and legs are also key.
• Plumage (Adult Female - Hepatic Morph). If you see a rufous-brown bird with heavy black barring on the upperparts and head, and barred underparts, it's likely a hepatic female cuckoo.
• Plumage (Juvenile). Look for a scaly, dark grey-brown upperparts with rufous and black barring, a white nape patch, and barred underparts. Dull yellow eye-ring.
• Behavior. Cuckoos are often secretive, perching quietly in trees or shrubs. They are not typically seen feeding young, as they are brood parasites.
