|opmerkingen||24 October, adult, wearing colour ring, photographed (A Holzem). 2018 was a record year for this subspecies. All six birds were colour-ringed as chicks in the Horsvær archipelago, Norway. Helberg et al (2009) considered this to be fuscus area, and this was recently confirmed by Baggot et al (2018). On plumage, only 2cy birds can be identified with certainty during certain months only. Therefore, in all other plumages only birds ringed as chicks within known nominate fuscus colonies are accepted. This certainly leads to a huge under-representation on the list and one may therefore wonder whether this taxon really is a rarity. Annual Report 2018.|
