I've had and bred cockatiels and lovebirds. I also hand-fed the babies. The lovebirds were SO cute after they were handfed - so colorful, like mini-parrots, but LOUD. I had male cockatiels that could really sing! They were out of the cage for the most part and had a 4 ft tall jungle gym that they loved climbing around on.
I love birds and I miss them, but they were loud and messy. Still, I'd love another one - maybe a calm little pionus - some birds are quieter than others. Eclectus parrots are quiet too and stunning, the males are green and the girls are red. If you want quiet - then stay away from conures! My friend had one that she spoiled rotten, and he would scream as soon as you put him down. Even though hers was rotten, they are quite the screamers.
