I have Callum sitting on the back of my neck currently, nibbling on my hair. While I love him to death, I don't know that I would recommend him for just anyone. I attend college, but I'm gone for only a couple hours a day, but then spend the rest of the day giving him attention, letting him roam around the house, and doing homework with him. Callum loves to try to bite my homework or my ear (because I'm not paying attention to him when he's resting so nicely against my head). I live with my grandma off-campus, so I don't have to worry about dorms, roommates, school rules, etc.
College is not cheap as you know. Can you afford the cage, toys, bedding, pellet diet, and fresh fruits every single day? Speaking of which, are you and your roommates prepared to have a bird try to take a bite of your food as you're eating? Callum does this to me. He'll nibble my lips and fingers if I ignore him. He'll try to reach and steal food from me.
Can you afford having a little rainy day fund for those emergency vet bills? I brought Callum to an emergency vet visit because he wouldn't open his eye. I spent probably about $300, $400 dollars on him that night. That was "lucky." I could've easily spent way more. Do you have a fund to pay for the normal vet bills? Avian vets are not cheap, especially when they're in an birdie emergency room.
Also, consider your neighbors and apartment building. I constantly see GCCs labeled as apartment friendly birds. At least for me, Callum would not be happy in an apartment. He wouldn't be allowed to be loud. Thin walls and a loud bird? That's a recipe for disaster, especially if your neighbors or office don't like you. Plus, not every apartment is bird friendly. If they are, they often have a size limit with something as vague as a "small" bird. What's their definition of a small bird? A conure, or a canary?
One thing I have to say with roommates... Be prepared! Your GCC may not want to bond to you and may instead end up bonding to a roommate that may or may not appreciate it. GCCs are also notorious for being a one-person bird. A lot of people say GCCs are quiet, but there is no such thing as a quiet bird. Maybe I just have the loudest, friendliest GCC on the plant, but Callum calls for me constantly (have fun training that out of him), wants to be near me constantly, and has also bonded to my grandma (who does not really want that, but tolerates it).
Also, I don't know what your roommates are like, but while you're gone at classes, they may be home and bothering your bird. Sticking a bird in a room alone in a cage is a surefire way to get a shy or aggressive bird. Are your roommates prepared to take care of this bird when you're gone? Do they want to? Do you want that? Callum's bitten my friends before because they didn't listen to me when I said to leave him alone and that he was getting annoyed with their petting. As small as these little cuties are, their bites HURT. Callum has only directly bitten me once or twice and that was because he spooked and because he got angry at a random thing and decided to bite my ear. Play some Youtube videos of GCC screams and squawks and turn the volume to max and play that. Over. And over. And over. Can your roommates and you put up with this?
I can't play video games, read a book, watch a movie, or even eat without Callum right there. Can you and your roommates put up with this constantly clingy bird? They want to do EVERYTHING with you.
You'll suddenly become the new, cool person because you have a bird. Trust me, you mention you have something other than a budgie, and people will instantly want to see them or just ask you about them constantly. I don't mind talking about Callum, but I don't want strangers begging to see my bird. I'm also just a recluse that doesn't like people tho lol.
I know this was not a fun post to read. It wasn't fun to type, especially since GCCs are such amazing little birds, but I have to be frank with you. I worry about you being a college student with roommates and in an apartment. I love Callum to death and I wouldn't trade him for anything. If I had to do it all again, I would. He's my little lovebug.
