I noticed that: when i am going close to the lovebird's cage, they both get into their nest and hide. If i stay here for some time, eventually ONE of the them, is getting out and sit on the nest's perch. Then it eventually fly to the bowl of seeds and so on, but when i do a sudden move, he immidiately get in the nest. The one that remains in the nest, it's the same one each time. I don't know what's happening. I have them for about 3 months i think and they continue do that habit. The one is really shy. Is that a problem? When i see them while hiding, i can see them both chiring and fly around. They hate me or what? I must tell that when i brought them, i was working on the cage for some upgrades. Maybe they are scared of that? What will make them "like" me again?

Thanks
