Regulidae

This is the family for kinglets and goldcrests. They, along with wrens, are claimed to have been called "regulus" in old Latinhttps://en.wiktionary.org/w/index.php?title=regulus&oldid=70578711, but I currently can't find proof of that. Wikipedia claims that (at least for these birds) it was because of their crowned heads, but doesn't distinct whether that's what they were named in their scientific name for and that it wasn't there in ancient Latin.https://en.wikipedia.org/w/index.php?title=Kinglet&oldid=1126485482
