Lorikeets are LOUD. I used to work in a pet store with exotic animals and birds, and OMG were they loud. Any sort of parrot or parakeet is going to have at least 1 screaming session per day. The larger the bird, the more your windows and eardrums will shake. Seriously.

Birds are very rewarding pets- I used to hand-raise cockatiels. If you do not get hand-raised birds, you'll be in for some trouble training them. Hand-raised can also mean different things to different people: there are businesses that claim "hand-raised" status, and all it means is that once a day, they cram food down the birds' throat. If you want a human-socialized bird, you're going to need to ask a LOT of questions from the seller.

If you're getting an exotic bird, you'll have to birdproof your house- they're going to be out of the cage more often than they are inside, unless you want the bird to pick up neuroses such as feather-plucking or shrieking from sheer boredom. If you have four-legged pets such as cats, dogs, rats, or anything else that may prove a danger to your bird, don't get it. You're sinking a lot of money, time and love into a creature who is very delicate in constitution. This also means getting rid of Teflon pans (the gases are deadly to birds) and making sure you do not have extreme temperature swings (of ten degrees or more) in your house. Do not keep them near a window or an air vent. Or the kitchen. Be prepared to vacuum at least every other day; birds will blow more dander and feathers then you believe.
You'll also have to be ready to feed the bird something more than the special diet pet stores sell. They mix up the special food and hope that you'll have to come back every month for their ix. Lorikeets eat a variety of berries, soft fruits and nectars- that means you'll be cutting up fresh fruits a couple of times a day. This also means very messy stools, which in turn means if you have light-colored furniture or carpet, you'll need to find some natural cleaners (remember, harsh chemicals will kill the bird) that will be effective on cleaning up used berry. Bird poop also smells very, uh, unique. Be prepared to clean the cage often. They also need their toenails trimmed.

Parrots in general are incredibly destructive. You're going to need to come up with some fascinating things for them to chew and destroy- it's an absolute MUST for them to live a healthy life. Be prepared to move anything that you don;t want chewed on into another room.

Fans in the bird's room/habitat are a no-no. That includes ceiling fans.

I'm not trying to dissuade you from getting a bird. Birds can be very rewarding, unique and funny pets. But they take a LOT of time (they are very social creatures) and are very delicate creatures.

I've been bitten by a great many critters. Bird bites are among the most painful things I've ever experienced.
