Ripe persimmon flesh is generally considered safe in small amounts, but information is limited and unripe fruit is high in tannins — so offer cautiously and remove the seeds.
Keeper's noteOnly fully ripe, soft persimmon — an underripe one is mouth-puckeringly astringent for a reason. Introduce a small amount first and watch how your bird handles it.
What to watch out for with persimmon
Fully ripe persimmon is soft, sweet, and vitamin-A-rich, and most sources treat the ripe flesh as safe for parrots. The caution comes from two things: unripe persimmons are astringent with high tannins that can cause digestive upset, and avian-specific data is thin. The seeds and any hard core should be removed.
How to serve it
Fully ripe, soft flesh only; remove seeds and core.
Start with a small piece to see how your bird tolerates it.
Skip dried persimmon (very high sugar) and any unripe fruit.
