list the names of birds and animals that ruin crops
Birds that damage garden crops include blackbirds, starlings, crows, thrashers, mockingbirds, sparrows, jays, robins and magpies. They often feed on young seedlings, including newly germinated seedlings. Protect seedlings with row covers or bird netting held away from the plants by wooden or pipe supports.
Animals with a pair of sharp upper and lower gnawing teeth can lay waste to garden crops. Those animals include mice, rats, voles, woodchucks, squirrels and pocket gophers. Squirrels harvest nuts, seeds and fruits right from the plants.
