[QUOTE This isn't a thread on the efficacy of pellets. But it is one on the accuracy and origins of the specific claim. [/QUOTE] Well that is an easy one to answer. Somebody is telling porkies. Birds may live as long as some other diets, on fabricated foods. But as for them being ideal! They are not. In fact I will put money on the fact that any bird fed on a 80% or higher pellet diet will die at at an earlier age than one fed on a good varied real diet. No matter what the species. Take for example 'Pellets for Lorikeets' Really? Which does lead to damage to their tongue. BUT HEY! You can buy them.
