No. Cardinals do not eat other birds’ eggs. They are primarily seed-eaters and have no interest in raiding nests. This behaviour belongs to jays, crows, grackles, and other nest predators - not cardinals.

| Fruits and berries | Dogwood, mulberry, wild grape, blackberry |

Protecting Cardinal Nests
Keep cats indoors - Domestic cats are the single biggest threat to nesting birds.
Plant dense shrubs - Cardinals nest in thick vegetation like holly, hawthorn, and privet. Dense cover makes it harder for predators to find nests.
Avoid disturbing nests - If you find a cardinal nest, leave it alone. Checking on it can attract predators that follow your scent trail.
Cardinals are peaceful birds that eat seeds, fruit, and insects. They do not raid other nests, steal eggs, or prey on other birds. If something is eating eggs in your garden, look at jays, crows, snakes, or cats - not cardinals.
