Description of Chestnut-Winged Cuckoo
Chestnut-Winged Cuckoo was first given its binomial name by Linnaeus in the year 1766. His description of what he called Cuculus coromandus was based on the notes of Brisson who described the bird as "Le coucou hupe de Coromandel" which was collected on the Coromandel coast of India (probably near Pondicherry which was a French colony). Buffon noticed the close relation to the Jacobin cuckoo and called it "le Jacobin huppe de Coromandel". The species was later placed under the genus names of Coccystes, Oxylophus before being placed in Clamator.
