Klaas's cuckoo

Template:Short description Template:Speciesbox Klaas's cuckoo (Chrysococcyx klaas) is a species of cuckoo in the family Cuculidae which is native to the wooded regions of sub-Saharan Africa. The specific name honours Klaas, the Khoikhoi man who collected the type specimen.

Name

The species was named by French explorer François Le Vaillant in 1806, in his book in recognition of his Khoikhoi servant and assistant, named Klaas, who found the type specimen. Le Vaillant wrote:Template:Efn

Le Vaillant's wish was honoured when the bird's first binomial name, Cuculus klaas, was applied by James Francis Stephens in 1815, and the tribute to Klaas has persisted to the present binomial.

The bird is the first known case of a species being named after an Indigenous individual, and Le Vaillant is one of the only colonial biologists to name bird species after local people. Edgar Leopold Layard nammed the brown-breasted flycatcher after Muttu, his servant.

Range

The species occurs throughout sub-Saharan Africa with the exception of very arid areas in the south-west.

Females have a bronze-brown body, greenish wing coverts and faintly barred white underparts. Viewed in flight, the male is largely white with dark primaries and females appear mostly brown. Males and females both have a small white post-ocular patch.
