Clapperton's spurfowl

Clapperton's spurfowl was described in 1826 by John George Children and Nicholas Aylward Vigors in an appendix to the Narrative of Travels and Discoveries in Northern and Central Africa by the explorers Dixon Denham and Hugh Clapperton. Children and Vigors chose to honour Clapperton and coined the binomial name Francolinus clappertoni.^[2] In their publication Children and Vigors did not specify where the specimen had been collected but the type locality was later designated as Borno in northeast Nigeria.^[3] The species is now placed in the genus Pternistis that was introduced by the German naturalist Johann Georg Wagler in 1832.^[4][5] A molecular phylogenetic study published in 2019 found that Clapperton's spurfowl is sister to Harwood's spurfowl.^[6]
