Welcome welcome welcome! Good advice above!
Okay- so now I am going off-topic because you said it's your first bird ever AND because Petsmart is notorious about not informing people new to birds about how to care for them (having accompanied my mom on a parakeet purchase there many years ago, and having watched a friend buy one there as well) .
I just wanted to make sure you knew about how sensitive they are to things in a home. I just posted this for a member who was asking about what could kill a bird, and as a brand-new owner, I hope you find this useful. If you already know it, ignore it and either way, again, WELCOME!
Teflon/PTFE/PFOA/PFCs -found in most products that heat or are intended to be heated (irons, waffle irons, electric skillets, pots, pans, egg-poachers, cookie sheets, popcorn poppers, air fryers, electric grills, panini makers, space-heaters, ovens, drip trays, roasting pans, curling irons, hair straighteners). These can kill through floors and closed doors. NOT all of these products contain it, but you must call to verify because it varies and just because a bird survived 10 Teflon exposures does not mean it will survive its 11th (and so on).
Fumes from chemicals- nail polish, acetone, glue, polish, paint,stains, aerosols, smoke, vaping, incense, candles, air fresheners, air fresheners, essential oils, candles, heated plastics, household cleaners that are not avian safe (e.g. bleach, lysol, windex, amonia, etc etc---anything chemical with a scent)
Burning foods, burning oil, smoke from a fire or burned plastic etc
Shock due to extreme temperature shifts/ drafts
Heart-failure due to an extreme fright or a head injury due to flying into something when scared.
Disease/infection (parrots hide illness as a means of self-preservation). They have to go to the vet often because they aren't like dogs and cats. Symptoms often are VERY small..Very important to clean everything after if you are not sure--carpet included.
Diet-- salt and sugar in high doses can be very bad. Avocado, chocolate, alcohol, caffeine, artificial sugars, rhubarb, onion, garlic (and anything from that family--can be toxic). A diet too high in fat (e.g., only seeds) can also lead to death over time. A bird with too much fat in his/her diet can have liver problems.
Vitamin overdose (from supplements) can also lead to organ failure.
Metal poisoning--- cages, jewelry and even toys can contain toxic metals. Stainless steel is really the only safe metal--even if they are just touching it with their tongues, they still ingest small bits of the metal. I know someone whose bird almost died due to playing with un-used toothbrushes (some contain small bits of copper alloy that is used to hold the bristles in place and the bird contacted them repeatedly and had to have chelation therapy).
Blockages-- a bird that ingests bit of cloth, plastic, fibers, nut-shells, corn-cobs etc can get blocked up- this can be deadly.
Egg-binding---if a female bird attempts to lay an egg and cannot (whether or not she was with a male bird) it can kill them.
