I had a black-capped lory. Yes, messy and loud. Their calls are a very high-pitched, ear-piercing shriek. They require special lory nectar food, not always that easy to find at pet stores. I loved him, great talker, absolute stand-up comedian, very interactive, but will never own another one. Also we went through one heck of a biting stage when he was a youngster, though that did get much better. And yes, I saw it out till the end. He died. I did not give him away. I have a real problem with people who don't keep their lifetime commitment to a parrot once they buy one. These birds form permanent attachments they never quite get over the loss of. I know because I had a couple of second-hand birds as well.
I had another bird person visit the lory didn't like. He wanted to bite her so bad but couldn't reach her, so he just aimed his back end at her and shot his liquid poop on her and it was intentional. True story. Yes, the walls behind the cage will catch it. I had to cover my walls around the cages with plastic.
Lories are not for the faint-at-heart and probably not the best parrot to start out with.
