Sandwich Tern Thalasseus sandvicensis is in the category of its synonym Category:Sterna, as well as Category:Thalasseus. Ditto all the other recent splits from Sterna.
Mediterranean Gull Ichthyaetus melanocephalus is only in Category:Ichthyaetus, and not in the category of its synonym Category:Larus. Ditto not all the other recent splits from Larus.
