I've done a lot of research on these guys, and they make awesome pets. Like a cross between a parrot and a puppy. They do require an all-fruit diet, and while the poop is liquid, only some individuals make a mess, others are quite clean. That huge beak has almost no jaw pressure, and though it is serrated, all they can really do is squeeze a bit. They're very intelligent and can be trained very easily, I've seen them play catch and do backflips. Since they cant climb like a parrot with those beaks, they need plenty of room to hop around, so wing-clipping will hurt them much more than other pet birds. I also think its great to have them able to fly around the house, since they do follow their owners like puppies. I personally can't stand parrot screams, I've grown up around them and it was the only thing that kept me from having one of my own (my best friend had dozens, and I practically lived at his house after school every day), so toucans appealed to me from the start. Aside from one species that has a melodious call, all of them are silent, but they do purr when content.
Basically, a perfect pet for anyone with the time, money, and space. Aside from those 3 aspects, couldn't ask for a better companion.
