So I showed Lucy the manikins. They looked at each other for a few seconds. Then both of the finches flew to the opposite side of the cage at once, and Lucy flew to the other side of the room, away from the cage. I guess you can say, she wasn't very impressed.

I might have to make an update thread for the dove. I've decided to put some paper in there to cover part of the wire bottom. I'm afraid the dove doesn't exactly know that he's supposed to eat the grit in the tiny bowl I put In there, and he needs it, as doves can't break seed shells open (they just straight up eat the seed, hull and all). So I was hoping to put some on the paper, so he could peck at it. However, the paper scared him so much, that he just flew from perch to perch, blew off all the grit. So I'm going to have to have to wait until he gets used to it being in there again.
I decided to try the taming method I read online. I used the little ranking system to determine that my dove is "moderately wild", where he will only fly away from me if I try to pick him up. Basically, I brought him to my bathroom, let him fly away from me until he got tired, and tried to get him to step up. After a few attempts, he finally did. I held my hand out flat, and had him stand on the back of it. He stayed there for a while, but his breathing was heavy, and he was obviously exhausted and scared. Judging by how much he freaked out to me putting paper in the bottom as well, I think I might need to wait a while longer, before I try this again. He may still need time to get used to everything.
