It’s not very unusual to see the skeleton of a dead sheep on the mountain above Dinas. I assume that the sheep die of natural causes and the crows do their job as carrion eaters. I have never seen the birds feeding but there are always plenty of crows about. For most of the year these intelligent birds clear up the countryside and even feed on maggots or ticks that threaten the health of the sheep. At lambing time, however, the age-old battle of crows v farmers is engaged in earnest when the crows, not content to just clean up the afterbirth, can attack both the newborn lambs and the ewes while they are at their most vulnerable.
It looks as if there are still some pickings left on this carcass whereas the bones that are scattered elsewhere across the grass are as white as stones.
