Lol @ large red edit .___.
You knew Id look at this lul.
Regarding the mirrors, some plain dont like them. Mine, for instance, doesnt give a damn about mirrors.
And always, ALWAYS keep their wings clipped >_> Even after having mine about 8-9 years now, hes obviously very tame (Hell, he wouldnt last outside anyway. Bugs scare him ffs >_>; ), I still keep his wings clipped regularly.
Clicker is kind of iffy, they can learn by treats too, but something like that is really just preference on how you wanna do it.
Main thing is, birds thrive on attention. Of course this is especially true with the large parrots, but even smaller ones like tiels need attention. How you go about it just depends on conditions at home I guess. Some people keep their birds out all day while theyre home, some only do a few hours a day.
Most stuff is really a 'as it comes up' sort of thing, since birds dont all act the same :x If you've already looked up information, you've probably already skimmed through most of the basic 'To-Know' information.
Also, as a rule of thumb, -most- things that are healthy for people are healthy for birds. They can have junk food too, but be smart about it, no chocolate or sweets or anything like that, and sparingly. Mine loves popcorn periodically *-*; And pasta/potatoes.
