Welcome to the comment room, RoseOFTheNight!
In regards to your second question (not the bio expert here, I'm afraid) -- "The Mirror" does demonstrate some memory-lapses, but all-in-all, it was confined to the individual's awareness of what was normal, not even what species they were. Granted, we have characters like Elisa and the rest of the Manhattan clan insisting right after the key spell changes that "we've always been human!" and the reverse, but the Manhattan Clan were effectively the only ones in that episode that actually were aware of the two species (not counting Demona, Puck, and the other non-featured characters like Xanatos, Talon, etc).
You'll notice that when Puck zaps rest of the island, all the humans-now-gargoyles are still going through their human routine -- riding the subway (not gliding) and still calling the gargoyles-now-humans 'monsters'. Even Elisa who IS aware of the two (and by episode's end, three) races briefly thought she was always a gargoyle very much had zero knowledge of gliding. I doubt any of the other New Yorkers were even truly cognizant of their tales and wings, lol. In short, if anything is clear, Puck wanted to make things as unclear as possible, lol.
TANGENT: PBS's Digital Studios's show, Monstrum had some lovely shoutouts to Gargoyles on Friday! Worth a watch -- https://www.youtube.com/watch?v=4E_RmBMH-6A
