What volume range represents the majority of the Eclectus parrot's daily fresh intake?

Around 70% to 90% of the total volume.

A healthy captive diet for an Eclectus parrot must overwhelmingly consist of fresh produce, generally cited as constituting 70% to 90% of the total daily food volume consumed. This high proportion is necessary because the bird’s natural foraging behavior in the wild centers around fruit, nectar, and pollen, resulting in a diet naturally high in moisture and carbohydrates but low in fat. This large percentage of fresh food is vital for hydration and supplying the necessary spectrum of vitamins and minerals required for longevity. If the diet deviates significantly from this high-fresh-produce standard, especially by increasing high-fat commercial products or seeds, nutritional imbalances and chronic disease become highly probable outcomes.
