Hi there

I am considering getting a bird. I already own 2 cats, a dog, and three rats. I would like a bird that is quite affectionate (but not a one-person bird). The other primary concern is noise at night. I do own my own home, but it is quite near other houses and I myself am in vet school and need quiet at night so that I can sleep and prepare for early classes the next day. My question is this: are parakeets RELIABLY quiet at night, or would this be considered an aberration? Thanks a lot!
