Your new friend is a totally awesome little bird highly intelligent so needs lots of things to keep that brain figuring things out this is no ordinary little bird you have selected to live with this is an awesome construction minded species
Lots of natural things little apple wood or willow wood perches for him to keep his feet flexible and claw at a good trim shape, places to hide in things like little cardboard boxes (no with colour printed sides just plain old cardboard boxes they do like to investigate things. Remember though introduce things gently sometimes if something is new they will be upset until they get used to it.
If you have a look in the training folder on site there are some brilliant training threads to help you ad your bird get to know each other. You speak human your bird speaks bird language so what you have to do is learn bird language each tilt of the head or fluff of the feathers or vocal call is telling you something your task is to learn what it means.
There are heaps of threads in the food section of what is good to feed like fruit and veggies etc and things you must never feed as they are dangerous like avocado and salt chocolate etc.
Your cage looks to be in the window, make sure that he is never in the direct sunlight all day long and can't seek shade being over heated by the sun coming through the window can be disastrous for a bird over heating can kill hence we tell people not to keep them in conservatories etc plus if they see something scary out there and feel they can't hide from it then that can panic them into battering themselves inside their cage. My birds can see out the window they are at the side of the window with the wall along side the back of the cage. so they can get into shade and also hide if they wish.
