If you want to attract more flying friends into your garden, you need to know what not to feed wild birds. It's a common misconception that you can give them food like bread or chips, but it turns out that you should avoid doing this for many reasons (which we'll get into later).
Instead, you should opt for the best bird food which is healthier, safer, and contains the nutrients they need. Or, if you fancy making them a DIY treat, you could learn how to make bird suet — our two-ingredient recipe is easy to follow and super affordable.
With the help of vet Dr. Rebecca MacMillan, we've listed eight things you should never feed wild birds and explained why they're a bad idea.
What not to feed wild birds
Nobody likes to see good food go to waste, so you might be tempted to feed the wild birds your leftovers. However, this can sometimes cause more harm than good as some kitchen ingredients, like onions, can be toxic. Here are Dr. MacMillan's big no-no's:
1. Bread: This might come as a surprise, but you should never feed bread to birds. It's not toxic, but it has no nutritional value and a "bird that fills up on bread will end up having an unbalanced diet".
2. Milk and dairy items: Since birds are lactose-intolerant, feeding them milk and dairy items can lead to serious digestive upset.
3. Bacon or bacon rinds: Bacon contains high levels of salt and additives which can be dangerous to birds.
4. Processed foods: Avoid processed foods, like potato chips, crackers, donuts, french fries, and cookies, which are unhealthy for them.
Dr. MacMillan says: "Although their high energy density is likely to be popular with wild birds, the sugar, salt, and unhealthy fats these contain are not great for their health."
5. Chocolate: Chocolate might be delicious for us, but it's very dangerous for our flying friends as it contains toxic caffeine and theobromine.
6. Onions and garlic: Onions and garlic are also toxic to birds and can cause health issues like ulcers and anemia.
7. Avocados: As avocados contain persin (a natural fungicide that's toxic to birds), you should avoid feeding them at all costs.
8. Raw dried beans: You should also steer clear of raw dried beans which contain a toxin that's dangerous for birds called hemagglutinin. However, Dr. MacMillan says that if they're cooked, they're perfectly safe to put in the best bird feeder.
Should I feed birds in my garden?
Now you know what you shouldn't feed birds, you might be left wondering if you should feed them at all... We can reassure you that it's a wonderful thing to do all year round - especially in the wintertime when food supplies are scarce.
You can attract particular birds into your yard by putting out specific foods that they enjoy (e.g. mealworms for robins). If you're feeling unsure, our feature on what to feed birds from your garden is a good place to start and has some great ideas.
Dr. MacMillan says: "Try offering mixed bird seed, peanuts (offer this as chopped pieces or in a feeder specifically designed for peanuts), and sunflower seeds. You could also try mealworms, either dried or live, which many birds enjoy as a protein-rich treat. Suet is often associated with the winter months, but during the breeding and nesting season, birds will also benefit from this concentrated energy source."
To keep rodent intruders at bay, you could invest in the best squirrel-proof bird feeder, use a bird feeder pole, or put tables away from walls or trees.
