(syn. Aviceda Ϯ Madagascan Cuckoo Hawk A. madagascariensis) Gr. νησος nēsos island (= Madagascar); genus Baza Hodgson, 1837, baza; "These constitute the genus Aviceda Swainson. In Madagascar a form occurs which retains the upper brown plumage, but underneath the throat continues the longitudinal spotting, and the rest of the under-surface is almost uniform through the bars broadening and overlapping. ... I propose to name this form NESOBAZA gen. nov., type Nesobaza madagascariensis (Smith). It appears to be a product of isolation from the African branch, in which the immature plumage is retained to a greater extent than in Aviceda." (Mathews 1916).
