1. What kind of bird do you have?
I have one cockatiel, one lovebird, two budgies, and a ringneck dove.
2. How long have you had your bird?
The cockatiel and lovebird - about ten years; dove - five years; budgies - three years, and two weeks 
3. Do you have/have you had other pets?
My family has had cats, a dog, fish, and rabbits. Currently just cats. The cats generally have free roam of the house and are shut in a room to allow for bird out of cage time. Aside from being huge pests whenever a new bird takes up residence (during which time I have to actively keep the cats from bothering it) the cats pretty much ignore the birds. I’m always around to keep an eye on things, though, just in case. (And when I can’t, the birds get shut in their own rooms.)
4. What is the temperament of your bird? Has its temperament changed since you got it?
Well, the cockatiel isn’t very keen on interacting with humans hands on, though she likes to be spoken to. She’s mainly laid back and pretty quiet. She gets hissy if you get too grabby, though.
Lovebird - fearless, very territorial (a female lovebird trait), assertive sometimes to aggressiveness. Not much for cuddling, but likes hanging out near/on me. Loud, though I imagine you knew that.
Budgies - playful, charming, vocal, always have to be in on what you’re doing and can be adorable nuisances sometimes. The current budgies don’t need as much human interaction as my previous girl, but I think that’s because she was an only budgie and thus bonded more closely to me. From what I’ve heard, this is pretty typical of pet birds - if you keep them with companions, they’ll bond more closely to each other than to you.
If you can’t spend a lot of time with a bird, though, it will get lonely without companions. They’re very social creatures.
Dove - sweet, calm, just wants to be cuddled/pet or perched nearby.
I wouldn’t say temperament has changed since I got them, but new birds do take time to settle in and come out of their shells. I generally take a “wait and see” approach to new birds.
5. Is your bird trained to do/say anything, if so, what and how easy was it to teach?
None of them are. It isn’t important to me so I never trained them and none of them have picked anything up on their own. I also often “talk” to them in my human-version of their calls (which they respond to really well, by the way - I’ve successfully struck up conversations with strange canaries in pet stores by imitating their chirps) so I imagine they feel even less need to.
6. Are your bird’s wings clipped?
Erm, no. I’m really careful about not letting them escape and they’re all well enough finger trained/handicapped (my cockatiel had something like a stroke a couple of years ago and has balance/sight problems that prevent a quick escape) to make it not an issue getting them back into their cages.
With the exception of the new budgie - his/her (too young to tell) wings came clipped and will be re-clipped if I’m not able to finger train him/her before they grow back.
I leave a door clipped open on their cages for out of cage time and let them come and go as they please (not all at once, though - lovebirds don’t mix with more passive/weaker birds) and fly around wherever they like.
7. If you travel, what kind of care does your bird require?
Supervision on long trips, plenty of food and fresh water for short overnight trips. I let cleaning go for up to a week when needed.
8. What are the enjoyable aspects of bird ownership?
I adore them in general. I love birds, and find my pet birds to be completely charming, adorable, and sweet. I love their vocalizations (especially the way they use bells to punctuate or make a point - dove isn’t a bell-bird, though), being preened, how unselfconscious and instinct-driven they are. And they’re always, always thrilled to see me. I’ve never know them to be grumpy, either.
9. What are the negative aspects of bird ownership?
Lots of poop (small and not very smelly, though), the noise factor sometimes, lovebird bites (like I said, she’s territorial), seed/pellet mess (they’re enthusiastic, especially when digging through mixes for favorite bits).
10. How do you feel about the whole cage/clipped wings/captive argument people make about birds as pets?
I feel really badly about keeping birds captive and controlling (limiting) their lives this way. They should be flying around Australia/Africa, living with a flock, choosing mates on their own, breeding if they have the instinct to. I know they live good lives with me and live a lot longer in captivity, but I really don’t feel I have the right to choose this for them, and of course I can’t ask them. I got the new budgie because my other budgie needed a companion, and I admit, it was easier to get a hand raised baby than to adopt an adult budgie needing a home.
I don’t know about the future - I love birds but they just aren’t domesticated the way cats and dogs do. They can’t live without us; birds can. I’m selfish enough to maybe keep getting baby birds from good breeders (and it is important to support good breeders) but I hope I’ll choose to adopt in the future instead.
Please note, I’m not calling you or anyone else who gets a bird from a breeder “selfish” - it’s selfish for me to because of the beliefs/feelings I personally hold. I don’t know what other people should or should not do - what doesn’t harm others and that they can live with, I guess. I just can’t help feeling guilty about it.
(And a lot of this is because my life has been very limited for several years due to health issues - mainly physical, some emotional - and I am suffering for it. Mainly for lack of interaction with other people and moving on with my life with regards to a relationship and family. So I probably project some of that onto my pet birds.)
This got really long. Sorry. Hope it was helpful.
