Why

Apple is a safe, hydrating treat that most budgies love, and it offers a little vitamin C and fibre. The one real danger is the seeds, which contain amygdalin that releases cyanide when crushed; because a budgie is so tiny, every seed must be removed. The flesh and skin are both fine once washed, making apple one of the easiest fruits to introduce to a nervous or first-time fresh-food eater.

How to feed it

Wash the apple well, as they are often heavily sprayed, then cut a thin slice and carefully cut out the core and every seed. Leave the skin on if you like. Clip the slice to the cage bars or offer small pieces in a shallow dish, and remove any uneaten fruit within a couple of hours.

How much & how often

A couple of small pieces two or three times a week is plenty. Apple is sugary, so keep it as an occasional snack rather than part of the daily vegetable bowl.
