like Chathams, Laysan etc. cheers Jeff.

unlike many terrestrial species, albatrosses and other petrels will always
be a taxonomic problem. The formal dogmatic definition of a species is
intended to put creatures into boxes where they can be uniquely classified
for human convenience. The Procellariiformes just will not adopt this
philosophy. Nature is not at our convenience and regardless BARC will remain
irrelevant to albatrosses.

I believe BARC has recently adopted the IOC taxonomy, and so Tristan
Albatross records would be considered now (there are several Chatham
Albatross and Atlantic Yellow-nosed Albatross records now listed as under
review). But that's only a recent thing

have personally seen two interesting candidates (both caught and measured by
SOSSA), but we did not get to a definite ID. As far as I know there is not a
single record of a Tristan Albatross accepted by BARC. Correct me if I am
wrong.
