Yes, all birds can be pluckers. There are many reasons why your bird may be plucking, let's hope it's psychological and not a physical health issue. Love birds get their name because they have a really tough time being alone. Does your bird have a partner? If not, you need to spend lots of time with it. They are very needy birds. They do not do good alone. Loneliness could be the reason. Have you changed your birds diet? His cage's location? Is his cage dirty? have you moved? Taken a toy away? Birds are creatures of Habit, they do not like change and takes them forever to adjust. Do you have her by a window? Some birds like that, some it is a source of stress. Do you have her on a seed diet? A seed diet is horrible for a bird's health, they need to be on pellets. If none of this is the problem, try spending more time with him. If that doesn't do the trick and she's still plucking, it's time to see an avian vet. A bird will hide his illness until he's on his death bed as in the wild, a sick bird is prey. We, as owners, must always watch out for any little changes. I wish you well!

Feather plucking is possible in all parrot species - it can either be illness, or a phsychological problem like stress or bordom.
