Feeding Small Caged Birds ------------------------- Smaller birds (canaries, finches, parakeets, cockatiels) should be fed as follows: Every day, offer greens (spinach, broccoli, carrot tops, celery leaves, parsley, etc.), grated carrot, grated cheese, hard-boiled or scrambled egg, canned tuna fish (packed in water), dry cereals, stale or toasted whole wheat bread (crumbled or in cubes), and small bits of other vegetables and fruits. Some birds may accept soft food items, such as peanut butter, cooked cereals, applesauce, and other strained fruits and vegetables.
