Segni di campo chiave

• Size and Color. Look for a very large, entirely black woodpecker. Its size alone distinguishes it from most other European woodpeckers.
• Head Pattern. Observe the red on the head: a full red crown in males, a smaller red patch on the hindcrown in females. This is a key field mark.
• Flight. Note its strong, undulating flight pattern, often with deep wing beats, as it flies between trees or across clearings.
• Vocalizations. Listen for its loud, powerful, and relatively slow drumming, or its distinctive 'klee-eh' or 'kru-kru-kru' calls.
• Foraging Signs. Look for large, rectangular holes in tree trunks, often at the base of trees or in dead wood, which are characteristic foraging signs.
