2 out of 3 of my children had 2 syllable first names, and one had 3. The one with 3 was named by Dh, lol!
I've heard that, too.
I hadn't thought about birds! Okay, let's see...
Marco (Marco Polo, but always called just Marco.), Diego, Captain, Juve, Killer, Critter, (A couple came named.) Mitred, Zorro...yes, this is a good cross-section, and enough to show me that most had 2 syllables.
Professor, is one with more.
Good addition to the question!
