Although Vesper is only about 2 1/2, I have had him since he was six months and have some experience with him as he is growing up. Might as well add my two cents
The Good: The good is always very good! Vesper SEEMS to be an oddball for citrons. (from what I've seen) He speaks rather clearly from what I've seen from other videos of the same species, and his language and vocabulary become better and more diverse all the time! He uses his words and phrases in context as well. He uses a sweet, cute little voice when he wants out of his cage. And when you say 'no' to him, he listens, but not after saying a cheeky "No!" and giving you a look with his crest pressed down.
Cuddling. He is a CUDDLER. But if he's on a mission or playing, he isn't really interested. But he does give kisses, and if you have some food he likes (i.e. crackers or home baked fries) he is
persistant!
And whenever he does something wrong (and he usually knows it), he will lean his head towards you and say things like "I'm a pretty bird! I'm a baby bird!" and he will rub his head on you and give you kisses. He is definitely saying sorry.
Also, when my mom has me on facetime on her phone and she puts the screen up to him, he will kiss my face on the screen

(Whether this is coincidence or not, I still think it's cute as all heck)
He's also a very good eater and eats both his pellets and fresh fruits and veggies every day
The Bad: He gets into everything. He has destroyed the latch on his cage and we have had to resort to something else to keep the one door shut. He will nip at your fingers if you try to move his cage to clean behind it (and he is still inside). In my experience, he has also been terrified of new people. Extremely shy bird. But, he seems to be getting used to people a little earlier, and I'm hoping to socialize him more when I come home for the summer.
In addition, he doesn't always want to shower. This can lead to him becoming grumpy because he hasn't showered and his pin feathers are bothering him

Oh, and bedtime is always tough. Gauging when it is the right time to put him in his cage can be difficult. He's usually VERY good, but if he's out for too long, you're in for a bit of a power struggle.
The Ugly: If you are not savvy with his body language, he can instantly become terrified of you or lunge at your face. Also be sure to keep any objects away from him that he isn't used to, otherwise he'll become all skinny and fly away! Not exactly the ugly... But I suppose when he was younger and we had a sitting hammock in the living room, he claimed it as his throne. I think this gave him a complex as he was always higher up than us, and he became extremely territorial and moody when he was on that perch. I removed the hammock, and have not had any 'alpha' battles since.
Overall I am absolutely in love with Vesper and would do anything for him
