great spotted cuckoo
The great spotted cuckoo (''Clamator glandarius'') is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners, the anis and the coucals.
It is a widespread summer migrant to southeast and southwest Europe and western Asia, and winters in Africa. It is a brood parasite, which lays its eggs in the nests of corvids (especially magpies), and starlings.
==Chicks==
Unlike the common cuckoo, neither the hen nor the hatched chick of this species evict the host's eggs, but the young magpies often die because they cannot compete successfully with the cuckoo for food. However it has been shown that this species' chicks secrete a repellent scent when predators threaten. The repellent protects great spotted cuckoo chicks themselves as well as the host's chicks from predators.〔(Great Spotted Cuckoo proved to protect invaded nests ). Lne.es (2014-03-21). Retrieved on 2014-05-06.〕 Carrion crow (''Corvus corone corone'') chicks survive better if a great spotted cuckoo chick shares their nest. Birds of prey and feral cats less frequently predate crow's nests that include a great spotted cuckoo chick. Crow chicks benefit only when predators are very active; when there is less predation, losing food to great spotted cuckoo chicks harms the crow chicks without compensation.〔(Smelly cuckoos protect hosts' chicks from predators ).
