Blue and Gold Macaw   

They are by far the most widely kept species. I would attribute this to the good availability of babies since this species has been found to breed quite readily in captivity. They need to be hand fed for three months or more. The Blue and Gold is what I would term a cool colored (cool meaning color temp) bird that a spectacular arrange of Blues, yellows, blacks, and greens. Coloring on this macaw is spectacular. I often take it for granted because there are so many around. In order for this macaw to be recognized internationally by the same name it has been given a scientific or "Latin" name. Belonging to the genus ARA the Blue and Gold is referred to as Ara-arauna. You may notice in the pictures that baby Blue and Gold’s have dark almost black eyes and older adult’s eyes turn a silver pale yellow.  For reasons not totally understood Blue and Gold’s have a greater tendency to pluck their feathers. Not all birds pluck and there certainly are ways to prevent plucking but this species is more susceptible When birds were being imported there seemed to be about three different sizes... one was quite large, then a mid-sized, and even a smaller species that was described as being more yellow and less orange/yellow. Unfortunately I believe the 3 species have been intermixed so much that these different sizes are becoming much less distinguishable. The smaller yellower species was described by Joan Abramson (author of The Large Macaws) as being “more high-strung and louder." It might have been nice to exclude this sub-species from being inter-mixed in with the nominate species. These distinct sizes and color differences are not noted in any other books that I can find, nevertheless the different subspecies have been confirmed by importers and ornithologists prior to the banning of importation. Blue and gold Macaws make wonderful pets if you are prepared to properly keep them. From the great number of birds being re-homed it is obvious that too many people don't plan ahead when obtaining this magnificent macaw. The blue and gold is a fabulous show-off and really loves to interact with people and new things. They need to be stimulated daily with things you can do with them and provide for them. Just like dogs, they like to go on walks, hikes, A day in the park, and maybe even a ride on the handle bars of your bicycle. Be creative and try mixing things up. Birds get bored of the same old routine just like we do. Available baby parrots
