The release of my partridges has attracted a few extra raptors into the area. Out feeding yesterday I watched a rather large buzzard hunting a hillside but fortunately the partridge are too wary for him and quickly moved off to a safer area. To combat crows raiding feeders I have placed garden canes in the ground next to all the feeders and tied a crow wing to the cane. (works fairly effectively) As the buzzard hunted he must have spotted one of these wings fluttering in the wind. Attack mode he swooped on the wing grabbing it taking the cane from the ground before he dropped it. Yes there are too many and can be a nightmare but still amazing birds.
