Offer small, clean portions
Introduce washed kale, broccoli florets, carrot tops or small pieces of bell pepper alongside familiar food. Use untreated food-grade produce, introduce one item at a time and observe actual eating. Remove soiled or wilting leftovers promptly. Greens add variety; they do not replace the balanced main diet or species-appropriate rearing food.
Identify the plant and its source
Confirm botanical identity before adding foliage, branches or seed heads. Avoid roadside collections, sprayed gardens, florist plants and unknown weeds. Washing does not reliably make chemically treated material safe. Keep birds away from potting soil, fertiliser and treated pot surfaces. Do not feed avocado or onion; fresh leaves are not equivalent to essential oils, which should not be diffused around birds.
Select and position branches
Veterinary safe-wood references include apple, pear and willow. Use correctly identified, untreated, sound branches; remove sharp projections, clean them and secure them against rotation. Offer varied comfortable diameters, leave flight paths open and keep food and water out of dropping zones. A safe-wood listing does not automatically approve every seed, fruit or other plant part.
