I posted a topic here surveying people with multi-bird (2+) households to see how they managed it:

Our Mango is actually a Maroon Bellied crossed with a Green Cheek - go figure. But the two species are almost the same for all intents and purposes...so here's our experience so far

He's so quiet it's almost unnatural. He only contact calls once a month or so (the shrill screech.) He's INCREDIBLY smart and trick-trainable (starting on prop tricks soon) and he was easily trained to click and whistle as a contact call instead of scream very, very quickly. Like I said - very, very smart and loves to train for treats. He murmurs in your ear and he'll beep with the microwave sometimes, but we live in the city and I'm thankful that to this day he just doesn't care about the constant ambulances and fire trucks and police cars screaming by and has never, ever screamed at them or tried to imitate the sound. Pyrhurra are known for being on the much quieter end of the spectrum.
He could care less for his toys most of the time, but not always. He goes through phases and favorites. He's a foraging-toy fiend, though. He's not a chewer unless it's really easily destroyed. He has no patience for the hard stuff

He naps and explores his cage - and I definitely agree with getting a much larger cage than recommended. He uses every inch of it and likes to climb around. I'm 5'2" and his cage is taller than me! I can very easily fit inside of it.
He loves to tunnel! If we're reading in bed and he's hanging out with us he becomes incredibly single-minded about exploring tunnels in the bed sheets. He loves to explore in general, but he's just as happy perched on my monitor and watching me type with one of his little feet tucked in.
He's the most cuddly bird I've ever met - and I hear that this is a tendency of the species. He will almost never turn down a head scritch and he'll ask for them all of the time. He snuggles up to your neck and grinds his beak. He's so comfortable on his back that he's fallen asleep in my hand more than once. He doesn't play with toys on his back, but he loves to hand-wrestle on his back. He's incredibly hand-tame and we can touch him anywhere and do anything to him. He was very tame when we got him and was very easy to tame even further.
He's calm and although he can have a hyper or cranky mood, he's mostly cheery. He has not picked either me or my fiance as a favorite person and we work hard to keep it that way - but he will sometimes have a mood where he really wants to perch on one of us instead of the other. He's never aggressive about it though, he just gives us the signals.
They can be nippy and he started out worse than he is now. He just "beaks" a bit but mostly uses other forms of body language to communicate his wants. He can definitely hurt (he's drawn blood once on each of us - just in the very, very beginning and it was our fault) but he hasn't hurt us since.
I do hear every so often that conures are the "Terriers" of the parrot world and I agree. He's alllll about hanging out with us, but when he sees something he wants he is completely single-minded. He gets his own dinner dish with his own goodies in it, but if we're snacking on something or if he
suspects we are putting food into our mouths secretly without telling him first, he will climb over anything and do anything to get at it. Not viciously or aggressively, just doggedly and dedicated to the cause. Over blankets, under blankets, up sleeves, over knees, up pantlegs, on top of your head and crane down over til he;s in the perfect position to snatch the food from your fork just before it reaches your mouth (I'm serious.) The upside is that he has absolutely no problem trying new foods. The downside is, while a dog will simply sit at your feet and whine a bit to beg for food.......this little devil will actively try, non-stop, to get at what he wants. Until he gets put on his playstand, that is, and then he just gets indignant about the whole situation
He definitely has a sense of self-confidence and pride and when he is indignant about certain treatment or handling he will let you know with some indignant squeaks and body language. You know how when a bird misbehaves or when he does a trick wrong you kind of ignore him or turn your back to him? Well, if you offend his sense of pride he'll do it right back at you. He's sassy sometimes (in an adorable way, because let's face it, he's smaller than a cockatiel.) He has a HUGE personality for such a little bird! His likes and dislikes, favorite foods, favorite tricks, favorite activities or words, favorite songs to dance to, very un-favorite songs he will NOT dance to...he's so much bird in such a small package. It's awesome.
He's just the perfect bird for our lifestyle because my fiance and I like to take walks (which he can come on) but we're kind of homebodies and we like to just chill - and he's cool with that.
Did you have any particular questions about anything specific?
