Ive heard that bird feeders can spread disease. Should I be worried?

It’s possible they can spread disease, but it’s also preventable. It’s imperative that you keep your feeder clean. This is especially true in the summer when hot temperatures can encourage the spread of disease. If you have a platform feeder, you’ll need to change your seed every day or two when it’s raining or snowing. Wet seeds can carry bacteria that can be harmful to birds.
