 Hachisuka believed the carnivorous habits described by Tafforet to be unlikely for a starling , and thought the lack of a crest suggested that it was not closely related to Fregilupus . He was reminded of corvids because of the black @-@ and @-@ white plumage , and assumed the bird seen by Tafforet was a sort of chough . In 1937 , he named it <unk> bicolor , and coined the common name " bi @-@ coloured chough " . Hachisuka 's assumptions are disregarded today , and modern ornithologists find Tafforet 's bird to be identical to the one described from subfossil remains .
