Yes — cilantro is safe, vitamin-rich, and a documented favorite of many conures.
Keeper's noteWash well; offer stems and all. If your bird inherited the human 'cilantro tastes like soap' gene's avian equivalent, parsley-free herb mixes still leave basil and dill to try.
Why cilantro is good for parrots
Cilantro (coriander leaf) carries vitamins A, C, and K in an aromatic package most parrots find exciting. Stems, leaves, and even coriander seeds are all safe.
How to serve it
Whole washed bunches clipped to the cage are ideal.
