Joan Gideon Loten had provided Edwards with a drawing of the bird by the Sri Lankan artist Pieter Cornelis de Bevere; [8] the original drawing by de Bere is in the collection of the Natural History Museum, London. [9] The palm cockatoo is, now, the only species within the genus Probosciger that was introduced by Heinrich Kuhl in 1820.
