they arent hard to keep care of.
All you really need to do is keep taking the eaten seeds (The shells I guess) off of the rest of the seeds, because they wont move the shells away or dig deeper.
KEEP THEM AWAY FROM WALLS TOO, they are pretty messy...
Clipping their wings is easy, you can do it with a pair of scicors from the drawer. I can show you what feathers to cut, just take a picture of the underside of their wing and I will show you (I have no clue where I could find a picture of one on the internet). Its really easy.
I gave my birds away because I got tired of cleaning up the mess they make!
Also, KEEP IT OUT IN THE OPEN. Keep it around people as much as you can. One of ours got really mean becasue it wasnt in the open very much, and since it was mean I didnt want to try to play with it either (It bit you every time you tried to open the cage)
And then the obvious... Clean the cage out, etc.
Actually as I think about it.... I have no clue what color of nose things mine had, but I do know I had one female (And that was the one that couldnt talk, also happened to be the meaner of all of them
Around here they will sell you a setup (Cage, food, and bird I think) for something like $25 or so.
