The Forbes’s Blackbird was long known only from the holotype in the British Museum at Tring, until Short & Parkes (1979) discovered several misidentified museum specimens of the species. They found that some specimens collected in Alagoas , in the expedition carried out by the MZUSP in partnership with the LACM between 1957 and 1958, had been misidentified as G. chopi . Short & Parkes (1979) , however, examined only those specimens deposited at the LACM, and not those at MZUSP, which remained misidentified and had their identification corrected later by Collar et al. (1992) .Thus, all specimens collected in Alagoas between 1951 and 1957 and formerly identified as G. chopi ( Pinto, 1954: 92 ; Pinto & Camargo, 1961: 273 ) are in fact A.forbesi (MZUSP 37714, 39281-39290; LACM 27134-27140).
