She's never been very vocal aside from occasional times where she's happy enough to "chatter" (I'd call it singing, but it sounds like chattering to me)v and cockatiels generally don't have a "human voice" (if you look up any video of a male cockatiel mimicking words, you will notice that they will almost always have a "raspy" voice).
It's basically all the vocalizations she's made so far since I got her back, which is narrowed down to chirps, soft peeps, and flock calling (aka screaming). She doesn't act like it hurts, though it still sounds weird, even for cockatiel standards. On the day I got her back, she would scream every time I left her field of vision, while she was eating while on the table. I tried not to leave for too long because of that, since I didn't know if it hurt or not.
And it's not that it's lower in volume. It's lower in pitch. Cockatiels have a fairly high-pitch voice, and hers is lower than average (and lower than it used to sound). It sounds almost nothing like it used to.
Would a sore throat cause voice hoarseness at all in birds? I know they don't have vocal chords, but I don't know how much the throat has to do with their voice.
She started flock calling when she saw a bunch of doves eating in the yard, the other day. I wonder if she knew some of them.
