Yes — mango flesh is an excellent source of vitamin A, which many parrots lack. Peel it first: the skin contains urushiol, the poison-ivy compound.
Keeper's notePeel it and cut off the pit — the flesh is excellent and most species go crazy for it.
Why mango is good for parrots
Vitamin A deficiency is one of the most common nutritional problems in pet parrots, and mango is one of the tastiest ways to fix it. The flesh is entirely safe; the skin contains urushiol, which can irritate sensitive birds (and people), and the pit is a slippery choking hazard.
How to serve it
Always peel; discard the skin and pit.
Cubes, spears, or mashed for chicks — all work.
Plain dried mango (no sugar, no sulfites) makes a good travel treat.
