I'm a baby Tawny Frogmouth... I'm not a frog, either!
Seriously, why did biologists/linguists/etc. ever think "fowl" was a fair term for all kinds of squee bird friends? It's a word that sounds far too close to another word that does not describe them in any way at all!
Trust me, you'd be grumpy too if you were having a bad feather day like that!
