When handling very large birds, it's best to have them well below your eye level because they can take advantage of a situation very quickly. Your eyes should always be looking downward toward the bird perched on your hand to ensure your dominant position. Birds will lead a very short life if you only feed them seed. Both Remmie and Ruby will lead full productive lives well into their 80's if proper care is given throughout their lives. Rembrandt requires 8 macadamia nuts as part of her daily diet.
Birds are very smart indeed.
Ruby is completely potty trained and will not dirty anywhere she's not allowed. Lady Rembrandt is still working on this one but is trying. Hyacinths are known to mature a lot slower than other breeds. Birds go through most of the same phases as children do growing-up. Puberty is reached at about 6-8 years of age.
