Some have even incorporated waterfalls, rope swings, and wooden jungle gyms as play items. This type of environment is not only more stimulating and healthy for the bird, but more enjoyable for their owners. Watching them swinging from a cotton rope, bathing in a small pool under a waterfall, or climbing all over a wooden structure is much more enjoyable then seeing them in a small cage. An ideal diet would include, seeds, nuts, fruits, vegetables and possibly some form of pellet diet as a supplement. They must be on a good diet long before you see the first egg to insure optimal fertility.
Extra calcium is often needed in the hen's diet and a good natural source for calcium is almonds.
Nuts are readily eaten by macaws. Breeding The decision to breed any animal should be made with great care. Breeding requires a great deal of commitment, time and expense. Blue and Golds, Scarlets, Militarys and Greenwings would likely produce young faster and more reliably than Buffon's or Hyacinth Macaws. I would suggest that a beginner start with some of the easier species first to determine whether this is really what they want to do.
