How about crows as predators for ducklings?

Crows can pose a threat to ducklings, particularly when they are vulnerable and unable to fend for themselves. These intelligent birds may prey on ducklings or scavenge eggs from nests, especially in areas where food is scarce. However, crows are opportunistic feeders and may not primarily target ducklings unless other food sources are limited. Overall, while they can be a risk, predation rates by crows on ducklings are generally lower compared to other predators like raccoons or Birds of Prey.
