Great Spotted Cuckoo
Clamator glandarius
The Great Spotted Cuckoo is a striking, long-tailed cuckoo of warm, open country around the Mediterranean and in much of Africa. It has grey upperparts spotted with white, a grey crest, a yellowish throat and upper breast and white underparts; juveniles are darker with a black cap and chestnut in the wings. It is a brood parasite of crows and especially of Eurasian Magpies. European birds winter in Africa.

About the species
Identification
A long-tailed, magpie-like cuckoo. It is dark grey-brown above with white spots, white below with a yellowish breast; the upperwing looks black-and-white and the head bears a clear crest. The bill is dark and slightly hooked, and the wings look broad in flight. Juveniles have a smaller, dark crest, buffy spots on the upperwing and rufous primaries. Told from Common Cuckoo by its spotted wings and crest, and from magpie by its all-white belly and cuckoo shape.

About the habitat
Warm, open country with scattered trees, olive groves, open woodland and scrub where magpies nest.
Diet
Mainly insects, notably hairy caterpillars that most birds avoid, as well as other insects, spiders and small lizards.
Behaviour
Lays its eggs in the nests of crows and magpies, but neither the adult nor the chick ejects the host's eggs, so the cuckoo chick is raised alongside the host young. The chick produces a foul-smelling secretion that deters predators and can improve the survival of the whole brood. Its flight is magpie-like, and the call a loud, chattering, repeated “cher-cher-kri-kri”.
