2. Parrots make noise. Sometimes quite a lot of it. It's important to realize "noise" is a personal thing. Some people find a budgie chattering or a cockatiel whistling quite annoying. I once had a person tell me their zebra finch was driving them crazy with all the noise it made. Other people find a conure screaming quite annoying. Then there is the top of the mountain noise level people who finally break at the cockatoo ear shattering shrill yells, or the megaphone macaw squawks. Personally, I'm a level 3 person because to me my sun conure screaming is a hum compared to one of my Amazons imitating a cockatoo screaming. Not even my macaw is that annoying.
3. Parrots make messes. Really big messes. They are very good at it. It's in their DNA. Flinging fruit around the rainforest just comes naturally. Totally destroying that $50 toy in one day, well every parrot needs to keep their beak in shape and sometimes destroy things just because they can. Even if a bird is born and raised to live with us, that wild bird personality is alive and well. They just can't help themselves, they must fling food, toys, and whatever else they can grab and fling. To not be messy would be quite boring for them. After all, a parrot's natural foraging instinct is a goal of getting to the center of things and not caring where the outer layers end up.
4. Parrots are picky. They are picky about what foods they like, what colors they like or hate, picky about what toys they will play with, and definitely picky about what people they like and don't like. Just because they loved a certain food or toy last week, doesn't mean it's still okay this week.
Patience is your friend when living with a parrot. They challenge us to help them enjoy a healthy diet, use their awesome intelligence in play and foraging, and encourage trust and love to help avoid the bite. If you love a parrot, then you are a pretty cool person. If you are loved by a parrot, then you are a very cool person.
