After six years, the committee took a decision on this very difficult bird. The underwing shows a clear white tongue on the underside of p9, probably in the region of 15-20% of the length of the visible feather. The underside of p10 does not show any sign of a white tongue, but on Scopoli’s Shearwater C diomedea c 2% have no white tongue on p10 and a short tongue in one or both of p9 and p8. In conclusion, this bird is probably a Cory’s Shearwater C borealis but Scopoli’s cannot be excluded with certainty (Flood & Gutiérrez 2021). Future DNA-research could provide a definitive identification. | |
