Fruits and veggies love birds- Sliver beets, red & green peppers, broccoli, dandelion, orange, corn on the cob or corn kernels, chick weed, banana, apple, celery, mung beans, snow peas, sunflower black/white, hemp, groats, carrot, Brussels sprout hearts, spinach, seeding grasses etc. hope that helps to you. for more information plz. search our sites: Thank you.
