yeah any of those two option can very be!
I will offer suggests on how I trained my birds....There are 2 types of words to a bird...an action or item. An action would be wings up, dance, step up/down. An item is say a treat (nutriberry, cracker, apple, banana, etc. when offer a treat specify what it is), toy, cage, etc. Pick words that relate to the type of action or item. Your training should be daily. It's like teaching a toddler child, except parrots never grow up like a human toddler does. TTry to keep it fun. Macaws love to play & they love fun. Act silly if need be.
He is easy scared specially when he sees birds flying.
Never thought of it… I would just take him for a walk as soon as I would see he is fine with the harness so Im gonna definitely take it more easy and show him everything better and baby steps.
Yes baby steps. Try to see what he sees that excites or scares him. Explain what it is & tell him it's OK. Touc it if you can to show him its OK. He's still a baby & learning.
We also going to add an outside aviary soon. Im hoping that will help him as well to see is normal all what he sees and hears outside.
Aviaries are great for getting them outside for fresh air & some sun. I suggest your aviary have a roof. Full sun is not good, as they can overheat. I suggest a swing or boing, several perches placed in & out of the sun (only as high as you can reach so you can get him down), 2 or 3 water dishes (I used the ones that twist off a base, for easy cleaning) placed close to the perches so you & he both can easily reach them & some hanging toys. Hanging toys can be hung from the ceiling or sides of the aviary close to a perch. I never feed outside, as to prevent bees from stinging. If it's hot, say mid 80's or higher I put ice cubes in the water dishes. My birds all love being outside in the aviary. My birds are trained to come down to go inside. I take 2 out in crates & one in a towel. Jasmine U2 loves towels, so she climbs down & runs right into a towel. JaKhu & Jengo (CAG) both climb down & go into their crates, as they are fully flighted. We take them out late morning or noon, if the temp is 72 or above. They get brought in late afternoon or no later than 6PM for evening meal. I mastered this by telling them they had to go in crates to go outside & back inside, then I put them in their crates. Soon they learned what I wanted them to do. It's all about using the same command words, asking them to do it & following thru.
How long it took for him to stip being nippy and how did you improve that behavior?
Or when he test your limits what would you do and how you show him not to since you are “the boss”?
Every bird is different so the time can be weeks to months. The key is be consistent with command words, asking the bird what it is you want it to do & be repetitive. I either walk away & ignore her or place her back in her cage & walk away. Wait a bit & try again. I did the same with JaJaBinks. One thing is for sure....you can not force a parrot to do what it doesn't want to. In time they learn.
Example: Tonight I was trying to teach JaKhu to stay on her cage. Up to now she has refused, climbing off & getting into things. Since she is very destructive, unlike JaJaBinks was, I can not trust her for a second. JaJaBinks loved her cage, was not destructive & I could trust her. I could let her out all day with no worries. Once we went away for 3 hours & forgot she was out. Came home to find her sitting on top of her cage looking out the window. She'd go in her cage, play on her swing, come out, back in, etc. Some times she'd come looking for me, but never tried to eat my house. My computer is in the same room as JaKhu & Jengo, so I can see her out of the corner of my eye. She'd climb down the side & try to get onto a stand where we keep treats in containers. I motioned my finger & told her to get up on her cage. She'd go back up & a few minutes later try again. See this is where they test you. I motioned again using the same finger & words. Back up she'd go. If she refused to go up I'd make her step up & put her back up. Finally when she refused to listen I put her back in her cage. End of lesson for tonight. We'll work on it again tomorrow & keep going until she learns.
Jasmine & Jengo both go in their cages on command. It took weeks to get them to do this working with them every day. Command words are "go in your cage". I'd place them in & shut the door. Eventually they learned it & now do it on command. I've had them both almost 23 years now.
I feel I need a better way to show Winter he cant control us since I do notice we do answer with an angry voice tone when he nips… specially my partner he can get a bit intimidating when he lose patience with his tone voice.
Reacting in angry loud voices only teaches them they will get a reaction/reward if they nip, scream, etc. I know it can be hard to ignore them when this happens, but it's best to ignore negative behavior. They eventually learn that negative behaviors will get no reaction, so they quit doing them. Only reward positive behavior. Positive behavor is sitting next to you & not nipping. So offer a reward, either phrase or a treat. He's not screaing, offer a reward.
Normally when we take him out I also try to hold him from one feet but he moves so much and doesn’t seem to like it when I do that. So he is always sitting in my hand or arm. And just when he is being good I let him go to my shoulder as long as he doesn’t get nippy. But since his nails are also very sharp I now also take a steak with me so he can sit there if he prefers
I would not allow him on your shoulder ever. All it takes is a second of excitement or fear & you could lose an eye, an ear or have a nasty bite on your face requiring stitches. It's not safe to allow a macaw on your shoulder. Grip one foot hard enough he can't wiggle away, but not so hard you cause him pain or discomfort. Say "let me have your foot". If he keeps wiggling give a gentle shake of your hand, not so much as you throw him off balance tho, & tell him to hold still. You can also use a travel perch, but then you have to lug it along.
Sharp nails: If you haven't started I suggest you try to do this now....rub his feet. Get him used to having his feet touched a lot. Try to file his nails using a large emery board file for acrylic nails. Hold the nail so it doesn't move back & forth. Some file nails thru the cage bars. Purchase a perch that will help naturally wear his nails down. Place it where he will be on it a lot, like in front of his food dish.
The sooner you teach these things the better he will be in the long run. Each thing you teach will take patience & time for him to learn. Try to keep it fun & reward all positive behaviors with phrase or a treat.
