Can I add fruit or vegetable seeds to suet or birdseed?

Kenn and Kimberly: Seeds meant for growing fruits or vegetables are generally more expensive than regular birdseed, so we wouldn’t recommend buying them for this purpose. But if you have leftover organic seeds that you won’t use in other ways, some of them are safe to feed to birds. It’s fine to offer seeds from squash, pumpkins, melons, peppers, pomegranates or tomatoes. Avoid using seeds from apples or pears, or the hard pits of peaches, apricots, cherries or plums, as these contain traces of toxic compounds that are harmful to backyard birds.
