I looked into it and turns out the issue is just what I suspected: it is being caused by the infobox template. Right after the infobox code ends, you will see the following line: For example, "Northern Cardinal (Cardinalis Cardinalis Cardinalis)s" category appears on these articles because of   - it is to automatically add category to the article (which has that infobox used in it) with the name of whatever is filled in   parameter and add a "s" in the end; and the infobox itself also has a   parameter which is filled as "Northern Cardinal (Cardinalis Cardinalis Cardinalis)" in the infobox on both of articles, and hence both of them are categorized as "Northern Cardinal (Cardinalis Cardinalis Cardinalis)s". To put it shortly, if you want to remove "Northern Cardinal (Cardinalis Cardinalis Cardinalis)s" from pages it is on, then just remove  from the infobox template - do the same with the other ones.
