Hi, how are you? I am sorry you are going through that. I do have experience with that situation. Regarding my finance, John, parrot named Suzy Q. Suzy Q was adopted to and is a B&G Macaw. Suzy Q is John best friend until ANY woman comes around. Suzy prefers women because Suzy was raised by a woman, if that makes sense. Most not all, but most parrots have a preference when it comes to male or female (as odd as that sounds). In general, Macaws are what I call "users". If they're preferred or "favorite" human is not around they will be cordial to those around them i.e. YOU because you are means of food and attention, even affection but, when lets say, your husband comes home you are no longer tolerated - lunged at, maybe even charged by your newly adopted macaw. They are mainly one person birds unless handed-raised and weaned and introduced to all kinds of men and women and children from an early age with good experiences. Now, from what I experienced, either your newly adopted macaw was raised by a male and this is why he/she prefers your husband when he's home OR this newly adopted macaw looks at your husband as a mate, especially if she's a female bird, and especially if he can take her out, pet her all over especially around the rump that's stimulating to a macaw(any parrot, really)and especially if this bird is acting protective as you approach while your husband is holding the bird. I don't know if you adopted from a rescue or CL ad whatever the case, in my experience, always ask, "Does this bird prefer men or women?" because most the the time, not all the time, most parrots have a preference. That preference stems from who raised them, where they owned by a man or woman beforehand, did they have a better experience with a man or woman. There is no way to know all this as macaws are not open book we can just read, you know but that's where you have to ask questions and know what ones to ask. Sometimes these rescues can't tell you the history of a potential adoptee parrot and that's where you just have to take a chance. I took a chance on my girl, Charlie, who's pictured as my avatar and it was the best decision I have ever made. John not so much, he has to work at a relationship with his bird and it's been 10yrs. As much as you want that macaw to accept you with your husband around, it may not happen, or it may take a lot of work on your part, bites to, but especially a lot of work on your husbands part to reprimand that behavior towards you since the bird looks to him as "favorite" and obviously has more respect to him. Now if it is this bird look at him as a mate and you as competition and this is a jealousy situation from the bird point of view that's a whole different scenario. First things first - Figure out what is going on in your new macaws brain - is hubby favorite or is potential mate? If you do not know I'd go back to where you got your macaw from and ask her/his history - who owned this bird, why'd it end up here, what'd they say about this bird when they dropped him off, where'd he come from, if you haven't asked this stuff already. I'd be curious to know if your bird was male or female. With my 3 birds - 2 of which were throw aways I, by their behavior could tell if they were male or female, I took my best educated guess, and took them to the vet to get dna confirmation and was correct. Watch your new friend, study her/his behavior, understand what behavior leads to what action. Never lose your temper and scream, or hit them, or throw a blanket over the cage you'll only deplete there trust in you and you will become enemy or predator. Neither is good. Hope all turns out well. It takes much time and much, much patience. You will be tested beyond belief especially with a macaw. It won't happen over night maybe not even a year from today. And DONT GIVE UP
It can happen just make it and take your time doing so.
