Apple is one of the most common fruits people offer their birds, and the good news is that most pet birds can enjoy it safely — with one important exception: the seeds.
The short answer
Yes — most birds can eat apple. The flesh is hydrating, mildly sweet and a favourite of many pet birds, from budgies to large parrots. The only real danger is the seeds (pips), so those must always be removed.
Why you must remove the seeds
Apple seeds contain amygdalin, which releases small amounts of cyanide when crushed. A person would need to chew a lot of seeds to be affected, but birds are tiny, so it is not worth any risk — always core the apple and remove every seed before offering it.
How to feed apple to your bird
Wash the apple well (apples are often heavily sprayed, so organic is ideal, or peel it), remove the core and all seeds, and offer a thin slice or small chunk. The skin is fine to leave on. Apple is sugary, so it is a treat rather than a staple — a couple of small pieces a few times a week suits most birds, scaled down for small species like budgies and up for larger parrots.
