Yes — strawberries are vitamin-rich and loved by almost every parrot. Just wash them very well.
Keeper's noteRed droppings after strawberries are normal pigment, not an emergency. Many a keeper has panicked over strawberry poop.
Why strawberries is good for parrots
Strawberries offer vitamin C, manganese, and folate, and their seeds and leafy tops are harmless. The only real concern is agricultural: strawberries consistently rank among the most pesticide-laden crops, so washing matters more here than for most fruit.
How to serve it
Wash thoroughly or buy organic; the tops are safe to leave on.
Halve or quarter for small species.
A messy fruit — schedule it before cage-cleaning day.
