Lovebirds are nice but they are totally devoted to each other (unless you get a single bird)...they couldn't care less if I was around or not...they just like me at feeding time! My female is quite aggressive as well...protecting her man I guess! I hear that is normal though...

I DO enjoy having them around, they aren't that noisy..a bit in the morning and early evening...the rest of the time they are busy sleeping, eating, grooming each other and doing the nasty!! :P
