A breeder would like to switch pairs to produce the best color combinations. A lost mate is not easily replaced. For the pet owner the disadvantage is greater. Like Amazons and many other birds that mate for life, the lovebird may pick out one person in the household and only be nice to that one person. It takes special attention from different members of the family to condition a lovebird to be loving to everyone.
Lovebirds can enjoy being a pet for the whole family.
He will go person to person seeking attention from everyone if he gets continuous socialization. After a few minutes the well raised lovebird will usually accept new friends. Depending on the bird's personality there will be an occasional person the bird may not care for. Two lovebirds together in a cage will bond with each other regardless of their sex. If you want your pet to be a buddy, keep him by himself and give him lots of attention.
