If kept alone and handled on a regular basis they will bond with you for life. Lovebirds are extremely playful and a blast to watch. They have never ending energy. They will go from toy to toy never seeming to tier. When tame they love sitting on your shoulder or like mine playing in my hair, and sitting on my head.
Lovebirds are affectionate and very smart.
They can be taught to step up give kisses. I have one that we taught how to whistle. Lovebirds can also become nippy at times. So when considering getting a lovebird you should take into account that they are a endless bundle of energy, and can be quite noisy with there chattering and shrill scream's. But they are no way as loud as my Conure.
