Ravens, Crows and Peregrines
On Friday morning we saw clear evidence that a pair of ravens are still present around the tower of Derby Cathedral. The ravens were feeding on a stored corpse of a lapwing (we knew this because we'd seen snipe, golden plover and lapwing corpses on the upper ledge the previous day). Not surprisingly, this annoyed our peregrine, though not to the extent it had earlier in the week. From time to time the peregrines made repeated swoops in an attempt to drive the ravens away. They took little notice, even when one peregrine hovered right above them for some moments as can been seen in the left-hand picture.
Both ravens later moved off to the roof of a nearby building and started pestering a crow. You can clearly see how much larger they are then their smaller cousin as the picture below shows the crow perching on top of a satelite dish.
