Before you have one in the house you should be aware that they are also noisy, destructive, messy and very demanding of time and attention. If not correctly handled they can be extremely aggressive. Their temperament often changes as they reach maturity due to hormones. That cuddy tame baby can become a "teenage" monster (at the age of three or four). Very hard to live with. Often they reserve their affection for one member of the household and are extremely aggressive to anyone else. Wild caught birds are particularly liable to do this. They are expensive to house properly and feed. They need lots of excercise. You WILL get bitten at some point! When you se a large macaw effortlessly crush a Brazil nut, think about it!
THEY SHOULD NEVER, EVER BE GIVEN TO A CHILD AS A PET. In fact children and macaws are best kept well separated, that beak is capable of hideous injury, even unwittingly.
They are extremely long lived, often to sixty years or more. Are you prepared to take on this responsibility for so long? What happens to your macaw when you die? If they are neglected or ignored they will almost certainly go insane and/or indulge in self injury, usually feather plucking. You will have to devote several hours every day to your macaw to keep it amused. It's like having a small child in the house.
Macaws don't make good talkers. Most learn only a few words, few speak clearly. Some can be taught "tricks" with time and patience, however this needs a very experienced handler. Anyone who tells you any different is lying.
There are hundreds of macaw refuges throughout the world for unwanted macaws that have been rejected by their owners. Many of these birds have been so neglected that they are insane or plucked. It takes years of care by very experienced handlers to correct their problems, some are beyond all help.
Yet still irresponsible breeders turn out hundreds of baby birds to foist on to the unwitting public.
