So it's been 6 months since I adopted Santina; but it's also been a few months since the macaw was introduced to the other two. I'd like to take a little time to talk about the flock dynamics that are emerging.
Initially, Kili had been an only bird. Then for a short time she shared the household with a budgie and eventually with Truman. The dynamic between Kili and Truman had always been where Kili was boss. Kili could take any perch from Truman at any moment. Truman got used to being the "little bird." Now things changed yet again with the addition of another bird.
Whenever considering the addition of another bird it is absolutely essential to consider how this bird will fit into the existing flock structure. You can't just simply say "I want this kind" and disregard whether existing birds will agree or not. When it comes to Kili, I know that she will bully any bird that is smaller or several times her size. This is why when I got Truman, I was only considering birds that were bigger than her that could handle the aggression. Even at triple her weight and 1.3x her size, Truman tends to lose most fights to her.
Santina is obviously much bigger than the other two but her personality also plays a big factor. She's not aggressive, she's slow, hulking, lazy. These qualities make her a lesser threat to the existing smaller birds. In fact, she would not go after them and they could out fly her any time, even if she could fly. So that's one side of the issue eliminated. On the flip side, the biggest danger is if the little guys put themselves in the way.
Initial introductions were to build favorable first impressions, start peacefully, and get the birds used to being around each other without causing trouble. However, beyond this early acceptance, the rest they have to work out on their own. This happens little by little through experimentation as the birds cross each others paths (whether intentionally or inadvertently).
The only trouble I ran into was that Santina finished her hazelnut quickly and started to pry Truman's nut out of his beak and scared him. The trick is to keep them busy with more nuts or to separate the birds before any trouble can erupt. This gives them a chance to get used to being around each other and not have aggressive thoughts. As sitting near each other begins to work, trick training the parrots on the same perch is also a great idea to teach cooperation.
Another thing that greatly improves the flock dynamic is taking the parrots outside together. Even if enemies at home, they tend to stick together outdoors against all the other mayhem. This socialization experience builds better bonds between the parrots that you bring home with you (with time). I've been taking the parrots out two and sometimes even three at a time. I put them down on fences or benches in close proximity to each other and keep them busy with training and food. They behave very well together in this type of setting.
Interestingly, Truman was never scared of Santina (more than triple his weight and size) from the very beginning. Kili, the bird that fearlessly bullies Truman, stays away from Santina. Kili is a true bully, she'll only pick fights she knows she can win. Truman on the other hand is the bumbling dodo. Truman will cross Santina's path thoughtlessly. And I want to reiterate that he's doing this in a non-aggressive way. When Kili goes after Truman, you can tell it is with malicious intentions. Truman on the other hand, doesn't actually go after Santina but he walks by her entirely focused on whatever he is after. Truman does not notice the far bigger macaw perched there and brushes right by her. His behavior comes off as bold. But his boldness is not in him thinking that he can take on the bigger bird but him not thinking at all. This is how Truman lands himself in trouble all the time.
This is exactly what happens between Truman and Santina. They have potential together as they are both non-aggressive birds but Truman is a bit of a dummy and puts himself in her way. Half the time this happens too quickly for Santina to react. Other times she runs away not knowing how this little bird can be coming right at her. Sometimes she puts her beak out defensively though. She does not attack or bite but simply tries to defend herself. Truman has been known to try to land on her and she needs to send him a reminder that her head is not a landing pad. Here's a video that perfectly illustrates the sort of character that Truman is:
First a word about each parrot's personality and the role it plays in the flock. Kili is the oldest (at least in my mind because I got her first, in hers as well I'm sure!) and for sure the most aggressive. As a Senegal Parrot, it's just in her nature. But I have trained almost all of that aggression out of her so she is super well-behaved. But there is no guarantee that she won't try to attack Santina and start a dangerous war. Truman is an easy going Cape Parrot. He has been bullied by Kili all his life and has become accustomed to having to yield his perch. He is absolutely non-aggressive and doesn't start fights. He is, however, stubborn and provoking. Until Kili gives him a good bite, he doesn't want to yield. Santina, being a green-winged macaw, is the biggest parrot. She is also a rescue with not a fully known history. She is extremely friendly and non-aggressive with me but she has been known to bite others. I have to be careful with her because she has the potential to hurt any of the other birds. But on the flip side I also know that she doesn't hurt anyone she likes. It will be important to get everyone to be on her good side.
The very first step in the introduction process has been to not do anything and just let the birds see each other through the bars from a distance. I did not want to overwhelm anyone by forcing an interaction prematurely. The next portion of the process is to begin the introduction in safe foolproof ways. There absolutely cannot be a fight or provocation. The birds must only get used to being near each other but without resorting to fighting. Since I am limited in being able to control what my parrots do, I have to shape the environment and interactions for success. The essential thing to prevent for now, is for two parrots to end up in close enough proximity to be able to start a fight for any reason. Thus the challenge is to bring the parrots closer together while keeping them apart.
To bring the parrots closer together without potential physical contact, what I have been doing is getting Kili or Truman in a grab (they like being grabbed so it's no problem) and holding them near Santina. I kept them out of biting range for sure. At first I kept them at some distance but progressively approached closer. This is a way to directly control the first interactions and helps me establish the relationship for both birds simultaneously. What I don't want is for them to establish relationships on their own terms because I don't know what those terms might be. I would rather take it slowly and ensure tolerance and ideally friendship between everybody. While holding one of the old world parrots in my grab, I would use my free hand to give scratches to both. I'd alternate between giving Truman a head scratch and then Santina.
By alternating my attention between the two birds, I deter jealousy and encourage mutual cooperation. You may recall that I encouraged cooperation between Kili & Truman by using the prisoner's dilemma in making them have to work together to get mega-treats. I would recall the birds to fly to me together and unless both came, neither would get the treats. They learned to work together for mutual success. Likewise, by requiring both Santina and Truman to be calm in each other's presence to earn head scratched, I am able to build a similar experience. Both birds were earning welcome head scratches that they would not have been getting otherwise at that time.
While holding Kili or Truman in a grab near Santina, I was carefully assessing each bird's body language. I was careful not to evoke any aggression while promoting responses most closely associated to contentedness. Nothing bad was happening to any bird but only good things. Interestingly, Santina was very calm. Although she showed some modest interest, she did not show the aggressive body language I have come to recognize that she makes when she ultimately ends up biting people. With Truman's approach, Santina simply turned her head around backwards and proceeded preening. This is definitely a sign of calm and trust. Likewise, Kili & Truman showed no aggression and enjoyed extra scratches.
By keeping the guest parrots in my grab, I was able to get Santina to associate some of the happiness she feels in seeing me toward seeing these other birds. They were a sort of extension of my reach. Santina's trust of the fact that anything I present to her is good, also helped. I repeated this grabbed showing exercise a few times.
The next step was to introduce some closer interaction with greater freedom without letting the parrots cross paths. I began working on flight recalls in the bird room with Kili & Truman. With Santina on a stand at the far end of the room, I gave Kili & Truman the freedom to fly in the same room as her. So even though they could fly up to her and start a fight, they didn't. They know how to focus on a training session and ignore all else during this time. This is where a focused training approach comes in really handy when introducing birds. The birds don't even have to know how to fly or do complex tricks. Just getting each bird to focus on some sort of known positively reinforced behavior (such as target) is a great starting point. The training creates sufficient distraction while also inadvertently reinforcing the parrots for being in proximity without contact. Santina wasn't neglected during this training time either. While Kili & Truman would be eating their treats, I would continue training with Santina as well.
By using pellets as treats for all birds, I was able to buy sufficient consumption time that I never had more than one unoccupied bird at a time. While the parrots were occupied eating their treats at distant ends of the room, there was no opportunity for aggression. With time and progress, I would have the birds end up closer to each other. I had Kili or Truman buzz right by Santina in flight to recall to me. They would ignore her presence and focus on flying to me instead. Since Santina was preoccupied eating her own treat during that time, she had little reason for concern either. Interestingly, Santina was not bothered or surprised to see these flying birds despite being clipped and living around clipped birds.
To take things even further, I began finding reasons to give a nut to each bird and putting them near each other to eat it. A nut is a really big deal for all of my birds and it keeps them so occupied that they notice little else while consuming it. I would have each bird do something to earn a nut and then put each on adjacent perches. None of the perches were in stepping distance of each other but the flighted parrots could easily hop or fly the gap if they really wanted to. But since all birds were preoccupied enjoying their nuts, nobody went anywhere and the all of the parrots had practice being in each other's proximity without doing anything undesirable.
These early introductions have been very successful. I will continue training the parrots near each other while maintaining separation. With time the separation will be reduced. I will also take the parrots places together. I have found that travel and socialization really brings parrots together in their familiarity with each other but not the new places. Lastly, at some eventual times the parrots will inadvertently come in each others immediate proximity and I will be evaluating the outcomes and whether or not they can be let together for any extended or unsupervised spans of time.
This is not an absolute approach to parrot introductions but it works well for me. This is the method by which I originally introduced Kili & Truman to each other and it worked. Now I am using the same for Santina. Having a good training background and well-behaved parrot in the first places are important requisites to having success with this introduction approach. So if you haven't already, check out my book, The Parrot Wizard's Guide to Well-Behaved Parrots to help you get to a point where applying this kind of training, being able to grab your parrots, etc are all possible in order to take advantage of these introduction techniques.
