There was a big bag of food waste, which had not been there when we walked up earlier. The seagulls were tearing at it, and then some jackdaws tried to get some food as well. They were shunted away by the much bigger gulls.
Then we heard raven calls, and two came, from the direction of the ravens nest. We were too far away to see which ones they were - I had to keep Miss Sophie sitting close because she tried a few times to join in with the seagulls!
