Parrots are incredibly smart, social and LOUD animals. They will require constant attention, care and enrichment. If not provided, they are very prone to depression, which comes with bunch of related health issues. They are fragile and require veterinarians that know how to deal with birds / exotic animals. They love destroying stuff and will destroy your house. For a bird that isnt just screaming all the time, you will have to feed them a balanced diet with fresh veggies, and ideally 12 hours sleep in a dark area.
I love parrots, and I took care of one for a time before, but I wouldn’t do that again until I am retired and settled down and know that I can dedicate myself to having one. You need to think about all the downsides and how to overcome them.
Have you thought about an easier animal with a shorter lifetime such as a mice or an hamster? They are also extremely sociable and smart animals and also can like to be handled. This would give you a “trial” run of sorts where you can think about how it would like to be have a harder to care animal.
Also, check out Clint’s Reptiles on youtube. He has a series of videos about various different animals and how easy / hard it is to care for them along with explaining their general personalities.
Parrots are the most surrendered animals in US and probably other countries. There are always more senior birds available at shelters.
