I have both a female Greenwing (13 years) and a female Umbrella (15 years) - I handfed them both from very young chicks, and both are free-flighted. We got both from quality breeders, and both have had a healthy diet of first Rowdybush and now Harrisons. They are both great birds. I cannot speak for all Cockatoos or all Macaws, just mine - a small sample!
I would also like to point out both my wife ad myself work out of our home, so they see us a lot, and their cages are in the busiest part of our home. I am a magician and use both in my shows.
They are both great birds, but very different. The Umbrella likes to snuggle, and she likes to show off. She is scared of nothing (In familiar territory), including our dogs (English Mastiff and Lab) - and she should be. She has no idea how small she is . . . Kyla, the Umbrella, is very much a DIva in attitude.
Jax, my Greenwing, is more nervous but not bad. She is well aware of her size in relation to the dogs. She enjoys attention too, but is not so Diva like.
Chewing - Neither are to be trusted with furniture!
Green wing = some
Umbrella = a lot
Dusty
Greenwing = no
Umbrella = a lot
Noise
is about the same,but for different reasons. Neither has a shrill call like a conure (which I can't stand).
Umbrella = Look at me noise
Greenwing = Where are you noise
Bite - nether bite much
Greenwing = generally more of a crush or a grind
Umbrella = two prongs on the bottom and the beak tip is more of a piercing
Tail
Green wing = Long and can get in the way for training and travel cages
Umbrella = Short, easy to travel
Cuddly
Greenwing = Yes, some
Umbrella = Every oppertunity
Plucking
Greenwing = some when she reached puberty at 10, but was put on birth control and it stopped.
Umbrella = a fair amount when she reached puberty, but it has stopped*
*Our umbrella reached puberty much earlier than out Greenwing, and we knew less. I don't think it would have been worse if we, and our vet, were more knowledgable at the time. FYI, we were feeding both Roudybush and switched to Harrisons and there has been a marked difference in both their feather luster and shape as well as their personality.
It is my experience that Cockatoos in general are more prone to feather pick than macaws, but it is my belief that it doesn't need to be that way. I personally believe picking is caused by multiple factors from diet, boredom, over-stress, lack of sunlight, improper sleep, changing hormones, socialization, as well as dependency on a person/thing that is removed.
Intelligence
Greenwing = The Brain
Umbrella = Diva
Friendly to strangers
Greenwing - really friendly
Umbrella = super friendly as long as they are amazed by her!
One Person
Greenwing = shows preference, but everyone can handle her
Umbrella = Everyone can handle her, but markedly flirty with me
Trick Training
Greenwing = more food motivated then crowd motivated then personal praise. Not hard to train tricks.
Umbrella = personal praise and recognition is a strong motivation, treats, not so much. Kyla is lazy, and just wants praise or to snuggle - with the exception of flying.
Perching
Greenwing = No problems staying on the perch
Umbrella = She is an explorer, and will not stay for long on a perch w/o direct supervision
Ground
Greenwing = She is wary to be on the ground and much prefers to be above it.
Umbrella = No problem exploring the bottom of her cage or the ground. She thinks she is a "bad-ass" in familiar territory. Loves scaring our Lab - so we have to be careful.
Independence
Greenwing = fairly independent i.e. she is not needy.
Umbrella = Much more emotionally needy, but not terrible. On the other hand, she displays much more love too.
Focus
Greenwing = has a fair amount of short term focus - which is good and bad. When training, she can focus on something other than training.
Umbrella = A lot of long term focus, not much short term focus. I.e. she will focus on demolishing a 2x4, but is easily distracted to snuggle, show off or explore. Not big on learning tricks that do not stem from natural behavior.
Eating
Greenwing = will eat like a pig if we let her.
Umbrella = More dainty and picky.
Confined spaces (I am a magician!)
Greenwing = Does not generally appreciate confined spaces, and with the long tail it can be difficult
Umbrella = No problem!
I hope this helps, and I am happy to answer any questions.
