How much money are pet toucans?
$4,000, perchance more.
Outside of that, they ARE expensive, and the ones you'll usually find hand fed will be the Aracaris - Most specifically Green Aracaris.. which will run you within the thousands.
Not to mention, they have an extremely specific diet that must be met, along with HUGE cage requirements, and they hold EXTREMELY messy poop.
Pet toucans? They are illegal. Pet Touracans aren't. They are related to toucans, but not as exotic.
