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.<ref name=pcr>{{cite book|author1=Rasmussen, PC  |author2=JC Anderton|year=2005|title=Birds of South Asia: The Ripley Guide.|publisher=Smithsonian Institution & Lynx Edicions. |volume=2|page=225}}</ref><ref name=payne>{{cite book|author=Payne, RB|year=2005|title=The Cuckoos. |publisher=Oxford University Press|pages=49, 320–325}}</ref><ref>{{cite book|pages=167–170|title=Fauna of British India.

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.<ref name=gaston>{{cite journal|author=Gaston, AJ|year=1976|title=Brood Parasitism by the Pied Crested Cuckoo ''Clamator jacobinus''.|journal=Journal of Animal Ecology|volume=45|issue=2|pages=331–348|doi=10.2307/3878|jstor=3878|bibcode=1976JAnEc..45..331G }}</ref> No ringing evidence exists to support the actual migration to Africa.<ref name=hbk>{{cite book|author1=Ali, S  |author2=S Dillon Ripley|year=1981|edition=2nd|title=Handbook of the birds of India and Pakistan.

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.<ref name=payne/> 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<ref name=payne/> however Rasmussen & Anderton (2005) suggest ''serratus'' as being the valid name for the Afro-Indian migrants.<ref name=pcr/><ref>{{cite journal|author=Ticehurst, Claud B|title=Systematic Notes on East African Birds.-Part XIV. 32 On the Relationship of Clamator serratus (Sparrm.), Clamator jacobinus pica (Hempr. & Ehr.), and Clamator hypopinarus (Cab. & Heine). |pages= 402–415|journal=Ibis| volume=79| issue=2|year=1937| doi=10.1111/j.1474-919X.1937.tb02182.x}}</ref><ref>{{cite book| title=Check-list of birds of the world.

In the past some other African subspecies have been suggested such as ''hypopinarus'' from South Africa and ''caroli'' from the Gabon.<ref>{{cite journal|url=https://archive.org/stream/novitateszoologi22lond#page/253/mode/1up/ |journal= Novitates Zoologicae|volume=22|year=1915|pages=244–266|title= List of a small collection of birds from Hausaland, Northern Nigeria|author=Hartert, E}}</ref>
