Before i begin let me just say that i appreciate that you are actually looking at the time and every aspect of caring for whatever bird you choose. I wish there was more people like you.
What you have mentioned with love birds are all true except for the noise. They are not loud at all unless you have like 20 living with you :O)
As like anything else there is always a way, it's just that a lot of people just want to do it the easy way and not want to do anything that goes out of there way.
You are right that if you have two they will most likely bond to each other. But, here's the tricky part, you can have two just don't house them in the same cage. If you decide to get two love bird get two cage and don't put them in the same room maybe one in your bedroom and the other one in the living room, where they have no eye contact or voice contact.
And if you decide to get a love bird your right a hand fed one is the best option, due to the fact that you will not have the time to tame a wild raised or an adult bird. An hour a day is fine. Most lovebird like my little george will just hang around the desk and hop around while i'm working, and since they are little, he would normally perch on my shoulder and go to sleep. And sometimes i don't even realize that he is out and on my shoulder. But if i were you i would just get one. They will bond with you for life and i think you will enjoy it more. The females have a tendency to get nippy when they get older i think it's the hormone, but the males stay sweet. George is almost 5 and he has never bit me. He used to have a mate but she passed away due to an accident. And ever since then i never got george another mate. He is much happier by himself. And enjoys the one on one time he has out with me.
As far as loudness, a love bird and a bugie pretty much make the same noise level, the only difference is that a lovebird can not learn to talk, i've never heard one talk.
And yes you need to spend time with them when you are home, but even just letting them out of the cage is good enough, as the name implies (lovebird) if your lovebird gets bonded with you, he will always just hang around with you, they are funny and would chirp in your ear when they are perch on your shoulder. They don't require much, as long as they are on you or around you they are happy. so you can do your school work and have him out at the same time. just make sure he don't get your pencil due to the lead and your homework, or else you will have to explain to your teacher that your bird chewed your papers :O)
My little George did that one time to my paper work. I decided to come home one day and bring my work home thinking i'll get it done and get ahead since i was busy, well..... while i was working the little stinker was out and playing, unnoticed he spotted one of my paperwork and chewed it where the only part that was left was sign here ooopppp! it was due the next day and i did not know how to explain this to my boss. So I did the best thing i could do. Brought the culprit to work. I took little george in his little carrier (and yeah since they are little it's easy to take em with you, I take George everywhere) and went to work. So when my boss came in, I went into his office and put George in my shirt pocket. He ask me if the paper where done and i said yes except for one piece of paper work. And he ask my why? so i took that piece out and he ask me if i shredded it by mistake and i said no. I said george did it. and he ask me who is george and i (at that time george was taking a nap in my shirt pocket) called george out and he peep his tiny little head and i said this is george. He laughed and told me that was so funny. and said that as long as i get it in today it's fine. but i think george prevented him from getting mad. he hop out and ran around his desk and he was so amaze on how tame george was and even told me that he would like to get a love bird for his daughter if it could be tamed like george.
well i hope that you enjoyed the story of George, they are fun and i'm not saying that parakeet are not fun. But if you want something that is a little bit different (a lot of people have parakeets) and a little bit more exotic try the love bird. Just make sure you get one from a reputable pet store or breeder. :O)
But whatever decision you make, just give em a lot of love and you will have fun with them. I call them dogs with wings, and i have 12 birds that live with me. and don't hesitate to ask anymore questions, they are always welcome.
By the way finding out the sexes on lovebird is hard both male and female can look alike and since there are several color mutation colors don't dictate the sex of the bird.
And as far as the nippy part, as long as you don't tease the bird they will not learn to nip, what i mean in tease the bird is don't poke anything through his cage, most people will do this not realizing they are actually teaching the birds to bite.
but if you spend a lot of time with them they will make a wonderful pet. enjoy on your decision and take your time looking for the right love bird. If they say that it is a handfed lovebird, the bird should not be afraid of people, i have breed this little guys for years and all that i have handfed and socialized while in the feeding stage would not be afraid of anyone. They are small birds with big attitude. George likes to mess around with my moluccan, which i don't tolerate but he will try to mess with him if given the chance, he don't know that he is just one bite and his gone. :O)
ok, i think i have said enough for now, good luck and have fun
stinky and me
