Why is a generous supply of Vitamin A-rich foods critical for Eclectus parrots?

They cannot efficiently convert beta-carotene into its active form.

Eclectus parrots possess a unique biological characteristic among parrot species: they struggle to efficiently convert beta-carotene, which is the precursor to active Vitamin A, into the required active form within their bodies. Consequently, relying solely on standard conversion rates or varying intake is insufficient; they require a direct and consistent, generous supply of foods that are already rich in Vitamin A. This essential nutrient is non-negotiable for maintaining critical functions such as healthy skin integrity, the proper function of mucosal linings throughout the digestive and respiratory tracts, and robust immune system operation. Vegetables like dark, leafy greens and brightly colored orange/yellow vegetables are paramount sources that must be included daily to prevent deficiencies.
