Eurasian Wryneck

• It turns its head almost 180 degrees and, if disturbed at the nest, twists its neck and hisses like a snake: which is why in English it has been called the "snake-bird".
• It is the only migratory woodpecker in Europe, although in Spain the behaviour varies: some populations are resident and others make moderate movements.
• Its main prey is ants, which it extracts from the ground or from rotten wood with its tongue, not by pecking at trunks.
