Answer: As a matter of fact, birds love the berries and eating them does no harm to your holly bush. If the berries weren't eaten, they would simply fall to the ground in the spring. The problem sounds more like a fungal disease than anything else. I'd prune away the affected leaves to keep the fungus from spreading. This will also open up your shrub to better air circulation, which should help it avoid additional diseases. The new growth it develops should be healthy. Finally, try to keep water off the leaves by watering the ground rather than the entire plant. This will also help your holly avoid diseases
Best wishes with your landscape!
