Hello and welcome! So glad you are considering research etc before buying!!! I feel like I always need to mention 2 major issues (see below):
Please read the following link (written by a real member of the forum very recently):

pfte/pfoa/fluoro-plastics/Teflon = Hidden in many things in and outside of the kitchen--they are in many microwave popcorn bags (clear-coat), microwave dinner trays, drip-trays, hair dryers, curling irons, curlers, ironing board covers/ironing boards, non-sticks pans/cookie-sheets/cake pans,irons, humidifiers, vaporizers, space-heaters, straighteners, air poppers, rice-cookers, air fryers, turkey roasters...anything that heats up in any way often contains inner components coated in teflon...These are deadly when heated...It can be clear, mixed with another metal, applied as a black coating or embedded in fabric...many weatherproof mascaras even contain teflon---it is not easy to know where it will be, so if something heats up (including your household oven) be sure. You will have to call the company and give the all abbreviations and full names (not just ptfe, but ptfe +polytetrafluoro blah blah blah).
Also, when you get a bird, you will not be able to use any standard cleaners. Nothing with a scent for the most part (NO bleach, lysol, soft-scrub, fabreeze, pine-sol, scrubbing bubbles, windex, ammonia, rubbing alcohol etc etc, acetone, nail polish, nail polish remover, paint, sharpies, SCENTED OR UNSCENTED CANDLES (natural or not(, essential oils, diffusers, spray on deodorant or other aerosols, carpet cleaners, flea baths, chlorine, bug spray, sunscreen, lotions etc...
Birds have
VERY sensitive respiratory systems..This is NOT an exaggeration. Your cleaners will be limited to : white vinegar +water (NOT BOILED---birds have died from vinegar in coffee pots), Grapefruit seed extract +water, and other avian safe cleaners. I recommend the yellow version of f10 SC as it is veterinary grade disinfectant which can be used around birds and does not have to be rinsed if diluted properly and allowed to dry).
