parakeet are usually very friendly, they learn fast too. Mine will give me kisses, he steps up on my finger to come in and out of the cage, and he takes treats from my hand. I have a sun conure as well and they are actually bonded together. When I have the conure on my shoulder the parakeet flies over to us to sit with my conure. They even share a cage. The biggest thing with getting them to step up in and out of the cage is space. I use to have a parakeet in a tiny parakeet cage and he hated me reaching in and trying tog et him out but once I got a bigger cage with a large door, he wasn't as afraid and my parakeet is so attached to my sun conure that he learned to step up and come out if I had the conure out first. now they both step up to go in and out of their cage whenever i want them to. Be careful of that string under him, they can swollow it and get it bound in them. Also, is he always ruffed up like that or was he just making himself look bigger? I notice the biggest thing with training them is if their cage is in sight they will likely keep trying to fly to it because thats their security. If you want them to bond to you and sit on your hand, finger, or shoulder then you need to take them away from their cage. Usually once you have them away you can work with them to step up from finger to finger and they usually aren't aggressive one bit. Also, I would get him a play stand to play on. It helps keep him off furniture and even yourself because they go to the bathroom like crazy but it gives them a place to be outside of their cage. My birds are on their playstand all day long as long as I'm home and they won't leave it
