On average, birds eat approximately 1/2 to 1/4 of their body weight every day. For example, a 2 lb. cardinal, a seed-eating bird, would consume approximately 1/2 to 1 lb. of seeds per day.
Among the most common foods that are toxic to birds are:
Chicks that have not yet opened their eyes may take 5-6 feedings per day (every 3-4 hours). Once birds' eyes open, they can have 3-5 feedings (one every 5 hours). As their feathers start to grow in, they may be fed 2-3 times per day (every 6 hours). Their crops should appear full when they're done.
Although bread isn't harmful to birds, try not to offer it in large quantities, since its nutritional value is relatively low. A bird that is on a diet of predominantly, or only bread, can suffer from serious vitamin deficiencies, or starve. Food left on the ground overnight can attract rats.
Ornithologists write that rice is perfectly safe for birds to eat. David Emery, urban legends researcher for the information website About.com, notes that wild rice is a dietary staple for many birds, as are other grains, such as wheat and barley, that expand when they absorb moisture.
Birds go bananas for bananas! First, remove the peel and cut each banana in half lengthwise. Then, you can set the fruit on a tree stump or skewer it on a hook. Another idea is to put a few chunks in a mesh bag and watch hummingbirds dart around to eat the fruit flies that gather.
Carrots are another vitamin-rich fresh food that is a favorite of many pet birds. 2 Containing high levels of beta-carotene, carrots can go a long way in supporting optimal eye health, which is important for birds of all species. As a bonus, carrots are flavorful and fun to eat!

Peanut butter is a good high-protein food for birds, and they can eat any of the same types humans do. If you're buying it specifically for birds, look for natural or organic types with the fewest additives. Try offering crunchy peanut butter for an extra nutty treat.
Porridge oats could also be a nutritious food source for the birds in your garden, and chances are you'll have them readily available in your kitchen. However, ensure the oats are uncooked as cooked oats could harden around a bird's beak.
Berries and small fruits, including blueberries, raspberries, currants, blackberries, mulberries, beautyberries, serviceberries, sumac, holly, juniper, and viburnum are especially popular with many birds. Birds also enjoy other fruits such as oranges, plums, apples, grapes, cherries, crabapples, and prickly pear.
Birds often start feasting on tomatoes just as the fruit starts ripening (as you've discovered). Unfortunately, by the time you notice, they've munched their way through part of your crop. Check out these options to protect your crop. One of the best solutions is to drape your plants with bird netting.
Baked goods: Stale or dry bread, bread crusts, donuts, cakes, cookies, and crackers are all appealing to backyard birds. Break the products up into small pieces and soak very stale pieces in water before offering them to the birds. Uncooked pastry dough is also suitable.
Oranges, lemons and limes can also be sliced into rounds, dried and hung up the same way. You can also hang the citrus fruits without drying them as they will not turn brown or spoil as easy as other fruits. Birds and squirrels will enjoy the fresh juices from these fruits.
Raisins and dried fruits like cranberries can be soaked in water over night before being offered to birds. Commercial dried fruit: some bird foods at your local market may offer a "nut, fruit & berry" blend. These are made for hopper and platform bird feeders.
Fruit. While a lot of birds that eat fruit will migrate in the winter, many other birds that stay in snowy areas year-round will enjoy the treat. Offer chopped apples, orange wedges, banana slices, halved grapes and melon rinds on platform feeders, spikes or nailed to trees.
