Ryan & Richard ]. Cuthbert Received 21 December 2007 Gough Bunting Rowettia goughensis is a large (60 g) finch endemic to Gough Island in the central South Atlantic Ocean. It evolved from South American finches and is closely related to Nesospiza buntings from Tristan da Cunha (Ryan et al. 2007), but also bears a strik- ing resemblance to Melanodera, a genus of finches found in southern South America and the Falklands (Lowe 1923). Gough Bunting was initially described as two species: Nesospiza goughensis for birds in the plain olive adult plumage and N. jessiae for birds in the distinc- tive, streaky juvenile plumage (Clarke 1904, 1905). Clarke assumed that the transitional immature plumage was the winter plumage of N. goughensis. Lowe (1923) corrected this misconception and, given its unusually long bill and apparent affinity to Melanodera, placed the species in its own genus. Relatively little has been published on the biology of Gough Bunting (Collar & Stuart 1984) and its nest and eggs were described as recently as 1979 (Voisin 1979). The species is currently listed as Vulnerable because it is confined to a single, small island (BirdLife Round Cone Lrt'sWife. 5 km Figure 1.
