I see a lot of people have multiple birds. I have one male ysgcc who's 1.5 year old now. He's funny and lively and loves to curl up in our hair on our shoulders. He's great, but sometimes my mind wanders... Since in the wild birds live in flocks, is it hard on them to live singly in captivity? And if they are flock creatures, why do people sometimes have trouble introducing more than one so much that they need separate cages for life? For those with multiples, how does it change your human relationship with the bird? And how often does a pairing work where the two could be kept together? Do you think birds need a bird friend for happiness? Or is lots of human attention enough?
