Energetically, I bet you'd spend more calories following the bird than any calories you'd gain from food you collect. On the other hand, I've been told that toucan is quite tasty.

Although, once you found the locations you could remember them or map them and then later trips would be more efficient.

Yes, but that probably isn't enough of a savings. We don't have a toucan's digestive system, and can't process large amounts of fruit quickly through our digestive tract like they can. It's a case of starving with a full stomach.
