Crows Destroying Nests

The crows in my yard have been destroying robin nests. Is there anything I can do to stop them?

George: By providing abundant nesting habitat in your yard, you're already doing all you can to protect robins and other songbirds from being discovered by crows and other predators. There's nothing you can do to crows because they, like songbirds, are protected by federal law. However, if it's early enough in the nesting season, the robins will renest.
