FWIW from the experience I've had so far, cormorants are the only bird I've had on my pond that would be a real threat to YP IMO. The GBH and GH seem to stick to shallow water and the king fisher sticks to pretty small fish. The cormorants dive to the bottom and can stay under water an incredible amount of time.
