First of all, welcome to the Board. My brother owns a rescue Military Macaw names Ricky. Poor Ricky has many issues sad to say and I believe they come from his previous owner and being neglected. First of all, if my Brother has company over, Ricky screams non stop, his company has to be entertained by going outside. Ricky is a one person Macaw but then again, lots of Macaws tend to have their favorite person. Ricky refuses to eat well, he will not eat fruit nor veg. He likes his pellet mix and nuts. He is very nippy even to my brother he loves. When I talk to my brother in the same room with ricky and my brother, he will bite my brother pretty bad and my brother has had many stiches because of this.
I own a Green Wing macaw names Neleno who is a one person Macaw as well, he is very quiet, very gentle with me. He kisses me a lot and that sometimes gets overwelming. I take Neleno my Green wing everywhere so our bond is very strong. I beleive that most Macaws or Parrots will be nippy once in a while, you just have to learn their body language and signs. Your most Gentle of all Macaws are the Hy and Green wing, then the Bluethroat, B&G, Military, scarlet Macaws. There are hybrind Macaws also out there but this is for the Large purebred Macaws. I would advise you before purchasing a Macaw is to spend time with a Macaw that you are interested in, learn as much about them as possible. Let the Macaw choose you, this means if you go to a breeder and she has 4 macaws, place all 4 on the floor, sit with them for a while and see what Macaw keeps coming back to you time and time again.Macaws will out live you so before your purchase make sure you have someone to take care of them if something happens to you. Best of luck on what you deside.Thanks Joe
