How is a house sparrow damaging to fruit crops?

A house sparrow can cause damage to fruit crops primarily by poking holes in grapes, cherries, and other fruits. This behavior disrupts the integrity of the fruit, leading to a higher likelihood of rot and disease entering through the damaged areas. The injuries inflicted can not only result in loss of quality and marketability of the fruit but can also encourage secondary pests and pathogens that can further threaten the overall health of the crops. While it might seem that other options suggest potential issues, they do not accurately represent the specific nature of the damage that house sparrows are known to cause in fruit agriculture. For instance, house sparrows do not typically chop down entire fruit trees or primarily eat leaves, nor are they significant predators of beneficial insects directly affecting fruit crops.
