Hi Diana,
Great article. Birds are very intelligent and owning a parrot is a treat. I have owned many over the years (rescues mostly and only a couple we purchased).
It is important to note that any one bringing home a new parrot should not spoil the bird with attention as much as figure out the amount of attention that can be given to the bird on a regular basis and be consistent with that goal.
Many birds that pluck are birds that when first bought were lavished with attention. Then when the owner got back into the normal routine and did not spend as much personal time with the bird it resorted to self mutilation. Cockatoos are well-known for feather plucking tendencies.
Owners with limited time can still enjoy a pet bird, but spend time in moderation from the start and allow the bird to learn how to entertain itself with activities and entertaining toys and treats.
Good points about them being social. Do not leave them in a room by themselves they are part of the family!
And smart they are. I know my birds understand sarcasm in my voice and laugh when they hear me say something sarcastic to the family. They are very wise.
One red-throat conure I had raised up from about 4-weeks old talked well, and when we had bought an 8-mo. old red-throat years later, she learned to talk from him.
