Pied Cuckoo Jacobin Nature Of Birds

The Jacobin cuckoo, pied cuckoo, or pied crested cuckoo (Clamator jacobinus) is a member of the cuckoo order of birds that is found in Africa and Asia. It is partially migratory and in India, it has been considered a harbinger of the monsoon rains due to the timing of its arrival. It has been associated with a bird in Indian mythology and poetry, known as the chatak represented as a bird with a beak on its head that waits for rains to quench its thirst.

This medium-sized, slim black and white cuckoo with a crest is distinctive. The white wing patch on the black wing and the pattern make it unmistakable even in flight. They are very vocal during the breeding season. The call is a ringing series of whistling notes "piu-piu" with the calls of the nominate form more rapid and slightly mellower.

In India the subspecies serratus (Sparrman, 1786) is a summer breeding visitor to northern India and is believed to migrate to southern Africa. This is larger and longer winged than the nominate subspecies found in the southern peninsular region and Sri Lanka is said to be a local migrant. No ringing evidence exists to support the actual migration to Africa

In Africa, subspecies serratus and pica (Hemprich & Ehrenberg, 1833) show two phases, a pied phase with white or whitish below and a black phase where the only white is on the wing patch. Mating appears to be assortative, with pied phase males pairing with pied phase females. An all-rufous color phase has been noted in Central Africa. There is lack of clarity on the migration and plumage variation involved. Subspecies pica has been said to be the form that migrates between Africa and India however Rasmussen & Anderton (2005) suggest serratus as being the valid name for the Afro-Indian migrants.

In the past some other African subspecies have been suggested such as hypopinarus from South Africa and caroli from the Gabon

The species is distributed south of the Sahara in Africa and south of the Himalayas in India. Also found in Sri Lanka and parts of Myanmar. Within Africa, there are movements of the species although they are resident in tropical Africa. The east African population is migratory and moves over southern Arabia into India during April.

The habitat of the species is mainly in thorny, dry scrub or open woodland avoiding areas of dense forest or extremely dry environments.
