Great Spotted Cuckoo
Clamator glandariusAlso known as Spotted Cuckoo
Great spotted cuckoos are striking brood parasites known for their loud, chattering calls and distinctive silvery-grey crests. Unlike the common cuckoo, they primarily target corvids, particularly Eurasian magpies, laying multiple eggs in a single host nest. The young cuckoos do not eject host eggs or chicks, instead outcompeting their nestmates for food through rapid growth and aggressive begging.

Safe to observe at a normal distance.
- Listen for chatter: Scan open woodlands when you hear their harsh, rattling alarm calls.
