uhuh, unlike that pellet-tree they all love to forage for in the wild
I am a bit more laid back (and I can afford to be, with species that can tolerate and even need a bit more fat in their diet ) and I will smell my birds - digestive issues always show themselves that way- even if the dropping looks okay.
Super-healthy is almost always a better choice, on the other hand if parrots follow dogs... the ones that get fed A-quality-doggyfood all their lives have shorter livespans than those that get tablescraps and leftovers as well ...
so since pellets are relatively new and going good but not great ...I will let them search out other foodstuffs as well
(and yes, the macaw loves cheese, Appie is obsessed with humanfood, so cheese is a favorite and Japie just wants the world to be made out of pellets and the incidentel pommegranate & nut )
