Azores Bullfinch also known as the São Miguel bullfinch, or locally in Portuguese as the Priolo, is an endangered passerine bird in the true finch family. It is endemic to São Miguel Island, in the Azores archipelago of Macaronesia in the North Atlantic Ocean.
The bullfinch is now largely restricted to a small area of native laurisilva forest at the eastern end of São Miguel, 300–-800 m asl, mainly centred on Pico da Vara in the Serra da Tronqueira range, but also seasonally (September to December) around Salto do Cavalo, further westwards in the range, probably of juveniles following post-fledging dispersal. It has never been recorded from the western end of the island.
Necessary for the recovery of the Azores bullfinch is to recover the available ecological enclaves of its northern archipelago of Macaronesia. The process of decline that suffers a significant portion of the endemic Azorean flora, is favored by the expansion of invasive alien plants. The projects dedicated to save the Azores bullfinch include the restoration of original laurel forest habitat, in the eastern monteverde of São Miguel.
