I actually completely forgot the mention of sloths. Also, there's an implication that actual birds exists, considering that Ruby says "Birdie no!", whereas if it was a normal Grimm, she probably wouldn't be so remorseful(?) about hitting it.

Perhaps the ranking of bestiality is Grimm > (Normal) Animals > Faunus > (Normal) Humans (obviously, from a human perspective). There's still a possibility that Faunus are seen as related to Grimm. Misunderstandings are common. once an idea goes into the mainstream, it's hard to shake it out of the populace.
