Taxonomy

This is a monotypic species[1].

Habitat

Breeds in heathland with occasional trees, Cork Oak Quercus suber being a favourite in Iberia. Also Olive Olea europaea groves.

Behaviour

Adopts Eurasian Magpie-like postures during the breeding season.
Hops on the ground

Diet

It's diet consists mainly of insects.

Breeding

It parasitises nests of the crow family (in Europe mainly the two species of magpies), and may lay several eggs in the same nest. In southern Africa the most common hosts are Pied Crow, Cape Crow and Pied Starling. In western Europe is a very early breeder, the adults have left the region by early June.
